1. Introduction

In case you have installed AVG Free Edition on your computer, and you are running a firewall at the same time, you might be experiencing problems while sending/receiving email messages and/or downloading AVG Anti-Virus updates. This Installation Guide refers to the firewall settings required for proper functionality of AVG AntiVirus. This document covers the settings instructions and recommendations for the following firewalls: Windows XP built-in firewall (Security Center) Kerio Personal Firewall Zone Alarm Pro firewall
2. Windows XP built-in firewall (Security Center)
Typically, the Windows XP built-in firewall default settings correspond very well to the AVG Free Edition configuration. Most probably no problems will occur at all. However, should you run up against problems, please follow these steps:
a) Windows XP Firewall Settings
Open the Windows Firewall settings dialog window: Start / Settings / Control Panels / Window Firewall On the General tab make sure the Do not allow exceptions option is not selected.

b) Define Exceptions

Switch to the Exceptions tab with the list of applications that are blocked to access to the Internet. You need to allow access to Internet for all AVG Anti-Virus applications. To do so, mark each check box related to an AVG application in the list of programs and services (see the following screenshot). For AVG Free Edition the applications to be selected from the list and marked as allowed are: AVG Free Control Center (file avgcc.exe) AVG Free Edition for Windows (file avgw.exe) avginet.exe avgemc.exe
If these applications are not listed in the list of exceptions, you need to add them manually. This can be done using the Add Program button:

c) Add a New Program

A new dialog window opens providing a list of programs that can be added to the previously seen Windows Firewall list of exceptions. Select the AVG applications from the list, and confirm adding them to the Windows Firewall list of exceptions by pressing the OK button (see the following screenshot).
In case you are not able to see any AVG application in the program list, you have to add them manually. Click the Browse button, and find the above listed files (avgw.exe, avgcc.exe, avginet.exe, and avgemc.exe) in the AVG Free Edition program folder (by default C:\Program Files\Grisoft\AVG Free):
Confirm adding the selected files by pressing the OK button in the Add a Program dialog window.
3. Kerio Personal Firewall
With the Kerio Personal Firewall you will probably need to configure the settings so that it is allowed for the AVG Free Edition (and its applications) to connect to the Internet (send/receive data), and to launch other applications (to update). To configure the Kerio Personal Firewall settings, follow these steps:
a) Run Kerio Personal Firewall b) Network Security
In the Network Security item (left menu), Application tab (top menu) you are able to overview a list of programs with the information on whether these are allowed to connect to the Internet. In the list, verify that all AVG applications are labeled as permit. If not, you need to change the AVG applications status. To do so, right click on every item and select the Permit option from the context menu.

c) System Security

In the System Security item (left menu), Application tab (top menu) you are able to overview a list of programs with the information on whether these are allowed to launch other application. Again, you need to make sure all AVG applications listed are labeled as permit to launch other applications (e.g. updates). If not, you need to change the AVG applications status. To do so, right click on every item and select the Permit option from the context menu.

Confirm all changes by pressing the Apply button.

4. Zone Alarm Pro

With the Zone Alarm Pro you will probably need to configure the settings so that it is allowed for the AVG Free Edition (and its applications) to connect to the Internet (send/receive data), and to launch other applications (to update). To configure the Zone Alarm Pro settings, follow these steps:
a) Run Zone Alarm Pro b) Program Control
In the Program Control item (left menu), Programs tab (top menu) you are able to overview a list of programs with the information on whether these are allowed to connect to the Internet. In the list, verify that all AVG applications are labeled as allowed (green confirmation mark). If not, you need to change the AVG applications status. To do so, right click on every item and select the confirmation mark from the context menu.

c) Add a Program

For AVG Free Edition the listed applications marked as allowed are: AVG E-Mail Scanner (avgemc.exe) AVG Update downloader (file avginet.exe)
If these applications are not listed, you need to add them manually. Use the Add button to open a new dialog window where you can specify the files on your local disk. By default, the files are located in the AVG Free Edition program folder (C:\Program Files\Grisoft\AVG Free).

d) E-mail Protection

In the E-mail Protection item (left menu), Main tab (top menu) you need to disable the built-in inbound/outbound email protection provided by the Zone Alarm Pro. By switching the Zone Alarm Pro implemented email verification off you will enable the more comprehensive AVG Free Edition email control.
5. Agnitum Outpost Firewall
You may be asked to allow network connection for some applications during their start up after installation of the product. This is related to products of AVG Anti-Virus System as well. You can set up the firewall so that it will permanently allow network communication for all AVG AntiVirus System applications. Doing this you will definitely not decrease the level of protection of your system. On the contrary, AVG Anti-Virus System will be enabled to fully employ all of its functions then, bringing the reliability of your anti-virus protection to maximum.
a) Allowing Activities for an Application
The firewall will react whenever an unknown application is trying to make a network connection. This holds even for AVG Anti-Virus applications before setting them up manually. The following window is displayed (for AVG Control Center in this example):
Choose the Allow all activities for this application option and press the OK button. Perform the same action whenever a similar window related to an AVG Anti-Virus application appears.
b) Configuring the Firewall at Once

However, you should allow the AVG Anti-Virus applications to access the network even before they try to open a connection. If you want to allow the network communication for AVG Anti-Virus applications (recommended!) at once, open the Agnitum Outpost Firewall main window:
Add the allowed applications by right-clicking on the Plugins item in the main navigation tree. Choose the Options menu item then. A new window will open then. Go to the Applications tab in the window:
Add all AVG Anti-Virus System applications currently installed on your computer using the Add button. Here is the list of all AVG Free edition applications that must always be allowed to connect to the Internet: avginet.exe application for performing online Internet updates of AVG Anti-Virus System (located in the Program Files/Grisoft/Avg7 directory by default)
avgemc.exe AVG E-mail Scanner for anti-virus scanning of e-mail (located in the Program Files/Grisoft/Avg7 directory by default)
Commit your selection by pressing the OK button. All AVG Anti-Virus System applications requiring the network communication should be fully operational then.
6. Sygate Personal Firewall
You may be asked to allow network connection for some applications during their start up also after installation of the Sygate Personal Firewall product. This is related to products of AVG Anti-Virus System as well. You can set up the firewall so that it will permanently allow network communication for all AVG AntiVirus System applications. Doing this you will definitely not decrease the level of protection of your system. On the contrary, AVG Anti-Virus System will be enabled to fully employ all of its functions then, bringing the reliability of your anti-virus protection to maximum.
The firewall will react whenever an unknown application is trying to make a network connection. This holds even for AVG Anti-Virus applications. The following window is displayed (for AVG Control Center in this example):
Check the Remember my answer field and press the Yes button. Repeat the action for any AVG Anti-Virus application that tries to connect the network.
If you want to allow the network communication for AVG Anti-Virus applications at once (recommended!), open the Sygate Personal Firewall main window:
Select the Advanced Rules menu item in the Tools folder of the main application menu. A new window will open then:
You can create a new rule for the AVG Anti-Virus System applications using the Add button in the Advanced Rules Settings window. Go to the Applications tab first:
Add all AVG Anti-Virus System applications currently installed on your system using the Browse button. Here is the list of all AVG Free edition applications that must always be allowed to connect to the Internet: avginet.exe application for performing online Internet updates of AVG Anti-Virus System (located in the Program Files/Grisoft/Avg7 directory by default) avgemc.exe AVG E-mail Scanner for anti-virus scanning of e-mail (located in the Program Files/Grisoft/Avg7 directory by default)

Go to the General tab then:
You have to allow any network communication for the selected AVG Anti-Virus System applications by selecting the Allow this traffic option. Commit the rule creation by pressing the OK button. All AVG Anti-Virus System applications requiring the network communication should be fully operational then.

1. Introduction

This AVG 7.5 Anti-Virus Free Edition user manual offers a general overview of the tasks and detection technologies provided by AVG Free. We will briefly talk about the program installation, initial startup, configuration and use. AVG Anti-Virus Free Edition is provided free-of-charge, and its functionality is limited. All functions provided within the AVG Free correspond to the AVG 7.5 Anti-Virus Basic Interface level. While using AVG Free you might discover you would like to have access to further and extended functionality of AVG as provided within the AVG 7.5 products. Then, please visit the Grisoft website at www.grisoft.com for information on AVG 7.5 purchase options. 1.1. AVG Free Detection Technologies The Anti-Virus component of AVG Free uses the following technologies to detect computer viruses: Scanning - searching for character strings that are characteristic of a given virus Heuristic analysis - dynamic emulation of the scanned objects instructions in a virtual computer environment Generic detection - detection of instructions characteristic of the given virus/group of viruses Where just a single technology might fall short of detecting or identifying a virus, AVG Free combines several technologies to ensure that your computer is protected. AVG Free is also able to analyze and detect executable applications or DLL libraries that could be potentially unwanted within the system. We call such threats Potentially Unwanted Programs (PUP). Such a program could, for example, be some kind of spyware, adware etc. Upon the user's request, AVG is able to remove such programs or block access to them. Furthermore, AVG Free scans your system registry for suspicious entries, temporary Internet files and tracking cookies, and allows you to treat all potentially harmful items in the same way as any other infection. 1.2. AVG Free Levels of Protection There are many ways a virus can enter your computer. For example, a virus contained in an incoming e-mail message is, upon receipt of the message, activated and stored on your hard disk, from where it can subsequently spread. An antivirus application which concentrates only on a single level of detection might fail in isolating the virus. AVG Free allows you to perform antivirus checks on multiple levels such as when you receive your electronic mail, as well as when you are working with files on your computer. You can also perform a check on demand. The following list outlines each level:

a) E-mail Scanner Checks incoming and outgoing mail by using plug-ins designed for the most frequently used e-mail programs. The E-mail Scanner is an additional program for electronic mail monitoring; it can run in fully automatic mode or you can configure it according to your specific needs (configuration is limited in the free version). The E-mail Scanner is designed for applications supporting the POP3/SMTP protocols. When detected, viruses are moved to the Virus Vault (where they are quarantined). b) Resident Shield The Resident Shield scans files as they are copied, opened or saved. When the Resident Shield discovers a virus in a file that is accessed, it stops the operation currently being performed and does not allow the virus to activate itself. The Resident Shield, loaded in the memory of your computer during system startup, also provides vital protection for the system areas of your computer. c) Tests Scanning is a crucial part of AVG functionality. You can run on-demand tests or schedule the daily test to run at a convenient time. The full version of AVG 7.5 Anti-Virus also allows further options for scanning an scheduling. It is vital to keep your AVG Free installation up-to-date! 1.3. Operating Systems Supported AVG Anti-Virus Free Edition is intended to protect personal computers with the following operating systems: Windows 98 SE Windows ME Windows NT Workstation SP6a Windows 2000 Professional SP4 + Security Rollup Pack Windows XP Professional SP2 Windows XP Home SP2 Windows Vista Note: AVG Free is not intended for use on networked computers! 1.4. Minimum hardware requirements Minimum hardware requirements for AVG Anti-Virus Free Edition are as follows: Intel MHz 30 MB of free hard drive space (for installation purposes) 32 MB of RAM memory
2. The Installation Process

5. AVG Control Center

The AVG Control Center is the AVG Free main control component. The AVG Control Center is launched each time a user logs on. You can use it to specify various AVG Free parameters and to monitor the status of each component. In the top section of the AVG Control Center you will find the Security status bar providing info on AVG Free status. There are three possible signs: Your computer is fully protected, up to date and all installed components are working properly One or more components are incorrectly configured and you should pay attention to their properties/settings. The problem components will be listed in the status error message. Indicates, that you have decided to ignore the reported faulty status of one of the components. Also, you can find the information on AVG Free status from the system tray icon. The full color (yellow, black, red, and green) of the AVG Control Center system tray icon on your Windows Taskbar indicates that all AVG components are active and fully functional. Gray icon coloring indicates a problem (inactive component, error status, old virus database, etc.). Double-click the system tray icon to open the main AVG Control Center screen to edit a component. 5.1. AVG Control Center - Environment

The AVG Control Center quick links (left menu) offer shortcuts leading to the AVG Free main components and functionalities, as well as the menu items in the AVG Test Center described in chapter 4.1 Left menu - Quick Links.
5.2. AVG Control Center - Components In the main box of the AVG Control Center you can see a list of components controlled from the AVG Control Center. To administer the selected component, just click the respective list item, and use the operating buttons in the bottom section of the AVG Control Center window. Whenever a components state is in error (e.g. the virus database has not been updated recently, and expired), the components panel within the AVG Control Center gets highlighted in red color to notify you, and the program system tray icon turns grey. It is recommended that you pay attention to this kind of notice, and keep the state of all components optimal in order to ensure the proper functioning of your AVG Anti-Virus Free Edition. To repair the components status, use the AVG Control Center application. The AVG Control Center allows management of these AVG Free components: Anti-Virus - contains information about all currently known viruses. Important: Updates are issued several times a week according to the current state of virus attack. If the virus database is older than 7 days, it is considered to be outdated. To signal this, the component changes its internal state to error and turns red. Please remember that reliable anti-virus protection can be achieved only if you update your anti-virus system regularly and frequently. Scheduler - controls planned task initiation. Resident Shield - performs on-access scanning of files and documents. Virus Vault - works as a store of suspect/infected objects, and provides options for their further treatment. Update Manager - controls AVG Free updates performance. Shell Extension - activates AVG Free functionality in the Windows Explorer application so that you can scan locations and objects within the Windows Explorer file browser by clicking the right mouse button and selecting the Scan with AVG Anti-Virus Free Edition option. E-mail Scanner - scans incoming and outgoing e-mail messages. License - provides information on the currently used license.
We would like to remind you of the AVG Free limitations: some AVG Free components configuration and functionality is restricted. You can reach the AVG 7.5 Anti-Virus options in full extent by purchasing the commercial version of AVG 7.5 Anti-Virus please refer to the Grisoft website at www.grisoft.com for more information.

6. AVG Virus Vault

The AVG Virus Vault application is a safe environment for management of suspect or infected objects detected during AVG Free scanning. Once an infected object is detected during scanning, and AVG Free is not able to heal it automatically, you are asked to decide what to do with the suspect object. The recommended solution is to move the object to the AVG Virus Vault for further treatment. Viruses can be detected by any of various AVG Free components, such as Resident Shield and E-mail Scanner. Viruses can also be found when running a test from the AVG Test Interface or even when using Windows Explorer. 6.1. What should I do when a virus is detected? Whenever AVG Free detects a virus, we recommend that you try to heal the infected object as the first option. When AVG Free is unable to heal the virus (this may occur for any of many reasons, including the distortion of the original file by the virus) use the next alternative move it to the Virus Vault. The last option is to delete the infected object (which is often the virus itself). 6.2. Why cant every virus be healed? In order for a file to be healed, it must be returned to exactly its original form! Because of this, not all files can be healed. The reason for this is that some viruses do not infect the original file but rewrite it, or they create copies of themselves. As such, it would not be possible to re-acquire the original form of the file (it would not be complete or would not exist at all once the virus is removed) or to ensure that the functionality of such a "healed" object was as intended in the original (e.g. in an executable program). In these cases, the only possibility to ensure that your data is protected is to remove the infected files from the (hard) disk and, when possible, restore the original file from your back-up. 6.3. What should I do with an unknown virus? When AVG Free has designated a file as being suspicious or as being infected by an unknown virus, you can e-mail the file to Grisoft (virus@grisoft.com). You can do so directly from the Virus Vault. Use this e-mail address to send files that you suspect of containing a virus, even when AVG Free has not detected any viruses. For additional help concerning viruses, please consult the FAQ section on the Grisoft Website at www.grisoft.com. 6.4. AVG Virus Vault Environment Every detected infected object should be moved to the Virus Vault. Within the Virus Vault you can explore the object, delete it, or heal and restore the object if the cure has been implemented already. Also, you can send the object to the AVG Free vendor for in-depth analysis. The Virus Vault offers a review of objects that have been detected as suspicious or infected, and provides this information about them: object status (infected / cured), object type (object / back-up), virus name, objects original location, date and time of the objects detection, file name, and file size.

7. Tests

One of the AVG Free main features is on-demand scanning. On-demand tests are designed to scan various parts of your computer whenever suspicion of virus infection arises. The recommended interval for complete system scanning is at least once a day. All the on-demand-scanning tests are run from the AVG Test Center environment. Tests can be also planned and run according to the preset schedule. You can change the test configuration according to your needs if you have an actual reason to do so. However, for less experienced computer users it is strongly recommended to keep the default test configuration. Different test types are available with vendor preset parameters, by default: 7.1. System Areas Test The System Areas Test will scan all system areas of your computer, and will detect and possibly heal or remove any virus found. 7.2. Complete Test The Complete Test will scan all hard drives of your computer, and will detect and possibly heal or remove any virus found. 7.3. Selected Areas Test The Selected Areas Test will scan all selected areas of your computer: you can specify the folders and files in your computers navigation tree. The Selected Areas Test target will detect and possibly heal or remove any virus found. 7.4. E-mail Scanner E-mail Scanner (EMS) checks all incoming/outgoing email messages. This component is controlled from AVG Control Center. EMS works as a filter between the e-mail programs you use (e.g. MS Outlook Express, Incredimail, The BAT!, etc.) and your Internet/e-mail communication provider. By default, right after installation EMS runs in fully automatic mode, e.g. it does not require any further configuration. However, if the communication is encrypted using SSL, it is not possible to run the EMS in automatic mode; you need to manually define EMS parameters. For details on the AVG EMS manual configuration please refer to the FAQ section of the Grisoft website at www.grisoft.com. Warning: If you work with Webmail (such as hotmail.com, msn.com, yahoo.com, etc.), you are using your Internet browser (for example, MS Internet Explorer) only to access your e-mail box, and your attachments are not downloaded to your computer until you access them. The main risk that you face in this case comes from e-mail message attachments. Because of this, your e-mail is not scanned by the available plug-ins, and scanning of the potentially dangerous attachments takes place as you access them. We recommend using AVG Free to check any executable file or MS Office documents that you receive through electronic mail.

8. Program Updates

Any anti-virus system can guarantee reliable protection only if it is updated regularly. AVG Free provides a reliable and fast update service with quick response times. Modern viruses spread very quickly and infect huge numbers of workstations in almost no time. 8.1. Update Levels AVG Free offers three update levels to select from: Priority update The priority update contains changes necessary for a reliable anti-virus protection. Typically, it does not include any changes to the code and updates only the virus definition database. This update should be applied as soon as it is available. Recommended update The recommended update contains various program changes, fixes and improvements. Optional update The optional update reflects changes that are not necessary for program functionality texts, updates of the setup component, etc. Optional updates can be downloaded and applied together with recommended updates but their importance is rather low. Within the AVG Free you are not allowed to create your own update schedules. The update is run daily, and you can only decide at what time it should be started. 8.2. Update Types You can distinguish between two types of update: On demand update An on demand update is an immediate AVG Free update that can be performed any time the need arises. Scheduled update Within the AVG Free a preset update schedule is configured by default. The planned update is performed once a day.

9. Firewall Settings

In case you have installed AVG Free on your computer, and you are running a firewall at the same time, you might be experiencing problems while sending/receiving email messages and/or AVG Free updates. Therefore we would like to provide you with the settings instructions and recommendations for the following firewalls: Windows XP built-in firewall Kerio Personal Firewall Zone Alarm Pro firewall 9.1. Windows XP built-in firewall Typically, the Windows XP built-in firewall default settings correspond very well with the AVG Free configuration. Most probably no problems will occur at all. However, should you run up against problems, please follow these steps: a) Windows XP Firewall Settings Open the Windows Firewall settings dialog window: Start / Settings / Control Panels / Window Firewall On the General tab make sure the Do not allow exceptions option is not selected.

Define Exceptions Switch to the Exceptions tab with the list of applications that are blocked to access to the Internet. You need to allow access to Internet for all AVG Anti-
Virus applications. To do so, mark each check box related to an AVG application in the list of programs and services (see the following screenshot).
