Whats included with McAfee QuickClean?
McAfee QuickClean uses safe and simple wizards to perform its major tasks. When you use a wizard to clean up your hard disk or manage applications, at each step you see exactly what you are specifying, and you can go back to previous screens and change options if you change your mind. Even if you are an expert computer user, wizards can automate tasks, such as removing junk files, that would otherwise be time-consuming or error-prone.
McAfee QuickClean wizards

Product Guide 23

Archiving a program using Archive
Use the Archive wizard to create a compressed backup copy, called an archive, of an application and remove it from your computer until you need it again. After the Archive wizard creates the compressed archive file, it removes the application from the folder where it was installed, but leaves the shortcuts to the application in place. When you click a shortcut to the application in the Windows Start menu Programs list, or on your Windows desktop, taskbar, or elsewhere, a message box appears, explaining that UnInstaller has archived the application and asking if you would like to restore it.
You can also use the Restore wizard to restore archived applications. Choose the Archive wizard if you:
Want to store useful applications that you rarely use. If you have old games or specialized programs, archive them to free disk space, but keep the shortcuts and other entry points available from your desktop. QuickClean keeps track of applications that you have archived. Their shortcuts and Start menu Programs list entries remain in place. If you click a shortcut or Programs list entry for an archived application, you can choose whether to restore the application.
Think you might need an application again. If you are not sure that you want to get rid of an application entirely, instead of using the Remove wizard and creating a backup file, use the Archive wizard and retain information.
Want to free space on your computer by removing an application temporarily. If you need disk space to perform a task that requires a large amount of temporary space, for example, you can archive applications to free the space. Then you can quickly restore the applications when you no longer need their disk space.
Monitoring a programs installation using BackTrack
The BackTrack wizard can restore your system to the state it was in before you installed a monitored application.
You must be running Windows 98 or Windows 98 SE in order to use the QuickClean BackTrack feature. You can use the QuickClean Installation Monitor to watch applications as they install making a record of every file that was added, deleted, or changed during installation. Then, you can use the BackTrack wizard to completely remove the monitored application from your computer and return all settings to their previous values before the application was installed. You can set up Installation Monitor in one of two ways:

Click Finish.

Restoring an archived program using Restore
The Restore wizard can completely restore any application if you have archived it or let the Remove wizard make a backup copy of the application before you removed it. The backup copy or the archive must still be available. To restore an application:
From the Advanced task is on the QuickClean Home Page, select Manage installed programs. Click Restore an archived program. From the Select an Archive to Restore screen, select the archive representing the program you want to restore and click Next. Select an archive or backup from the Restore wizard list and click Next. On the following screen, the names of all files that will be restored are displayed. Do not deselect any files if you are restoring an entire application. If you deselect files, critical application files may not be restored and the application may not run correctly, or at all.
Click Next. The Replace Existing Files? screen displays. Choose one of the following:
M Only replace older files with newer files. M Always replace existing files.
M Never replace existing files.
Click Restore to begin restoring the application. When the wizard restores the application, it displays a message that the job is completed. You can click Report to view details of restoration activity.

Restore deleted files

The Restore wizard can also restore individual files that the SpaceMaker wizard has deleted if QuickClean made backup copies of the files.
To restore individual files: 1 Repeat steps 1 through 5 above.
Select the files you want to restore from the list that appears in the next wizard screen; then click Next. Click Next to restore the selected files. The Restore Results displays the details of restoration activity.

Delete backup copies

QuickClean backs up deleted files and applications so that you can restore them if you change your mind later. Backup files, which are compressed files containing copies of all deleted files, are stored on your computer in a location you can specify in the Folder settings screen or in other locations that you can specify when you run one of the QuickClean wizards. Although backup copies are compressed, eventually they will take up a lot of disk space. When you are sure that you will no longer want or need a backup of a deleted application or group of files, delete the backup file.
To delete a backup file: 1 From the Advanced task list, select Manage installed programs.
Click Restore an archived program. The Select an Archive to Restore screen displays and within the Task pane a Related Tasks list displays. Here you can:
M Browse for an archive. M View a report about the selected archive. M Delete the selected archive.
If you are sure that you no longer need the selected archive, click Delete. At such time, you are prompted to confirm deleting the file.

QuickClean Activity Logs

When you click the Activity Log in the QuickClean main window, you will have the option to view different reports that displays numeric and graphic information about actions performed by any of the QuickClean wizards (e.g., summary, report logs, disk analysis and file analysis). Report Summary displays a complete list of files that were deleted or modified by each individual action. These reports can be useful in tracking down old versions of files that were deleted but backed up, or were archived.
Report Summary of all QuickClean reports Description This page shows numeric data about the total number of files affected, the total size of files moved, compressed, or deleted, the disk-space savings, and so on. The pie chart on the right shows the percent of disk space regained by the selected action if you are viewing a specific action report, or by all QuickClean actions, if you are viewing Master Log information. This page lists all changes made by the individual wizards. If you are viewing Master Log information, you see a list of available action reports. Click Open to chose an action report to view. Changes to Your Files and Hard Drive report The Disk Analysis page displays the percent of total disk space regained by deleting, moving, or archiving files in each file category. The File Analysis displays the total number of files in each category. If you only want to see what QuickClean has done, you can review the list of actions displayed in the Reports window. However, if you want to keep a record of QuickClean actions for later reference, you can print the report information or save it as a file.

How to Free Disk Space

About QuickClean Lite
The QuickClean Lite wizard enables you to clean your computer of unnecessary files and free valuable hard disk space. You can use the QuickClean Lite wizard to perform any of the following cleaning tasks:
Clean your Recycle Bin. Remove files that accumulate as you browse the Internet. Files of this type are stored in folders called Temporary Internet or Cache folders. Remove Shortcuts without an associated program, application, hypertext link, etc. Delete lost file fragments. Delete Windows Registry information, shortcuts, and system file references for applications that no longer exist on your computer. Delete temporary files. Remove deleted and sent messages from a Microsoft supported e-mail client (i.e.: Outlook, Outlook Express). Delete Most Recently Used shortcuts.
How QuickClean Lite works
First, the user selects the types of files they wish to remove from their computer. Next, the QuickClean Lite wizard scans the contents of the hard disk and identifies all files meeting the user-selected criteria. The user proceeds with the cleaning task if they are satisfied with the results of the scan. Finally, QuickClean Lite provides a graphic representation of the amount of reclaimed space after deleting the files.
Deleted files are not backed up. You cannot restore files deleted by QuickClean Lite.
QuickClean Lite cleaning options
The final removal process used by QuickClean Lite is to either use normal Windows deletion or secure file deletion using McAfee Shredder. Normal Windows deletion allows the recreation of deleted files using an undelete type of program. McAfee Shredder prevents file restoration programs from recreating deleted files by securely removing files from your computer.
The QuickClean Home page displays the default hard disk in your computer under Drive Info. If your computer is partitioned, or maintains more than one physical hard disk, select the specific drive wish to clean from the Select a Drive drop-down pick list before starting QuickClean Lite.
How to run QuickClean Lite from the CD
If your computer maintains a limited amount of hard disk space, you can still use QuickClean Lites functionality to remove accumulated junk from your computer. To run QuickClean Lite from the CD:
Insert the McAfee QuickClean installation CD into your computers CD ROM drive. The Autorun image displays. Select Run QuickClean Lite now. The QuickClean Lite Home page displays. Select the cleaners you want to run and refer to the on-screen instructions to complete this task.

About SpaceMaker

Freeing specific amounts of disk space on a drive
If you need a specific amount of disk space on one of your drives, click SpaceMaker in the QuickClean screen and tell the SpaceMaker wizard how much space you want, what kind of files it can delete, and whether you want it to make compressed backup copies of the files. Then let it free space for you. By default, files are backed up before they are deleted. The compressed backup uses less disk space than the deleted files, and gives you a chance to recover deleted files later. Each time you run the SpaceMaker wizard, you can turn off backups or specify a different location for the backups. Choose the SpaceMaker wizard to:
Quickly create free space on one of your drives. You can specify the drive and the amount of space you want to free. As soon as SpaceMaker frees the specified amount of space, it stops deleting files. If you choose to free as much space as possible, the wizard continues to delete files until it can find no more files that are old enough to delete in the categories you have chosen.
Delete files from more categories than QuickClean. SpaceMaker lets you delete files that some users might need, such as bitmap and multimedia files, backup files that have the.BAK extension, temporary files that Windows or Windows applications generate, screen savers, online help files, and so on.

Run a Custom rule.

No file is deleted if it has been modified or accessed within the period specified by the Advanced Settings screen. The default period is 180 days.

Custom Rule Creator

Overview
The Custom Rule Creator allows you customize your cleaning tasks. If there are specific folders or (for example) types of files that you want to remove from your computer, then you can create a custom rule to rid them from your computer. The Custom Rule Creator enables you to search for and clean files.
. located in a specific drive or folder. with specific file extensions. For example, you may want to clean.zip files (zipped or compressed files),.doc files (MS Word files), or.log files (log files). If the extension list box does not display the specific file extension that you want to search for, you can add a custom extension directly in the Custom file type text box.

. based upon the age of the file. based upon the size of the file (in Kilobytes).
To create or run a custom rule
Please refer to refer to online Help for specific instructions about how to create and run a custom cleaning rule.

Please refer to on-line help for additional information about how to use the wizards described in this section.

Browser Cache Cleaner

When you browse the Internet, your browser copies each Internet page and its graphics to a cache folder (temporary Internet files) on your hard disk. The browser can then load the page quickly if you return to it again. This is a useful feature if you repeatedly visit the same Internet pages and their content does not change. Most of the time, however, the cached files are not useful and can be deleted. The Browser Cache Cleaner helps you to quickly get rid of these cached files that may affect your computers hard disk space and performance.

Browser Cookies Cleaner

Cookies are small files that your Web browser stores on your computer at the request of a Web server. Each time you view a Web page from the Web server, your browser sends the cookie back to the server. These cookies can act like a tag, which let the Web server track which pages you view and how often you return to them. The Browser Cookie Cleaner wizard helps you to quickly get rid of these files that may jeopardize your privacy and security while browsing the Internet.

E-mail Cleaner

With the amount of e-mail you receive in just one day, cleaning your e-mail messages can be a big task. Use QuickCleans E-mail Cleaner feature to help you get rid of old messages that you no longer need and importantly, you do not want others to have access to.
ActiveX and Plug-in Cleaner
ActiveX is a technology used by software developers to implement controls in a program. An ActiveX control can add something as simple and useful as a button in a programs interface. Most of these good controls have been signed, meaning that they are harmless and will do nothing bad to the data on your computer. However, less than honest people can use ActiveX technology to write programs that can jeopardize the security of the data on your computer, such as a program which searches your hard drive for certain file types and sends the information in it someone else. Similarly, plug ins are small, special-purpose applications design to perform specific control in a program. For example, a plug-in module incorporated into your Web browser software. Use the ActiveX and Plug-in Cleaner to get rid of any of these items that may cause harmful effect on your computer.

You can select McAfee Shredder properties to specify the shredding level to perform. You can select: Quick to shred the information once; U.S. Government Multipass to make seven passes of repeatedly erasing the data; or Custom to indicate how many passes to make which allows up to 99 passes.

Shredding selected files

If your computer is running on Windows Me, some files even if shred, may be retained on your PC since these are protected by the Windows Me System Restore. You can shred files using drag and drop, which is a fast way if all the files are centrally located. Or if the files are in several places, you can shred them by starting McAfee Shredder and selecting the files to erase.
McAfee Shredder allows you to shred files on your PCs Recycle Bin, Temporary Internet, as well as Web site history folder. You can also specify the number of shredding passes (1-99) and can now have the option to shred an entire drive. Refer to the online Help file to display step-by-step instructions on how to shred selected files and non-file data.
After you shred non-file data, you will not be able to undelete any deleted files that utilized this information.

Advanced Cleaning Tasks

Registry Cleaner
View and remove unconnected registry entries Using QuickCleans Registry Cleaner makes maintenance and troubleshooting of your computers registry database a quick and easy process. It helps you clean the registry database of your PC by showing you key entries that may refer to files that have moved or no longer exist.
Always be careful deleting registry keys, values and settings. The Registry Cleaner displays registry entries for programs that are no longer installed in your computer. This wizard is only designed for maximum end user control, and not for safety. There are no safeguards in the wizard that would prevent you from deleting registry entries your computer needs, so always exercise caution before you decide to select a file to be deleted.
