Deleted files are not backed up. You cannot restore files deleted by

There are two methods you can use to start the QuickClean Lite wizard.

From any VirusScan Professional screen click the “Other tasks” Task, 
and select Start QuickClean Lite.

From the Windows task bar click the Start button, point to Programs > 
McAfee > McAfee Shared Features and click QuickClean Lite.

For additional information about using QuickClean Lite refer to online Help. 
You can access online Help for QuickClean Lite by clicking Help on any 
QuickClean Lite window.

When you save a file in Windows, it is stored in multiple pieces (in clusters 
made up of multiple sectors) on the disk. Windows also saves a road map, or 
index, that points to these clusters in two copies of the FAT (File Allocation 
Table). The FAT contains the directions to all the pieces of your files, so that 
applications can find them again later.

In addition to FAT file systems, McAfee Shredder supports New Technology 
Filing System (NTFS). NTFS is the file system used by Windows NT, Windows 
2000 and Windows XP.

When you delete a file, all the information stored in that file is not actually 
erased from your disk. Instead, Windows simply frees the clusters where the 
file was stored, making those locations available in the FAT. Thereafter, 
applications can write new information to those clusters. This means that all 
or part of your files can be reconstructed even after you delete them. Undelete 
programs can reconstruct a deleted file very easily, especially immediately 
after you delete the file and before you save any new information that might 
be written over the deleted file’s contents.
