virus removal from System Restore
Courtesy of MikeM.
Joan There really is no need to be concerned about any virus in the _RESTORE archive as they are harmless there and can only cause problems if you later choose to restore to a checkpoint created AFTER infection and BEFORE you cleaned your system. Something I doubt you will be doing. Any worms, trojans and viruses in the _restore archive will automatically be discarded in due course as newer data is archived and the older files discarded The problem with disabling system restore is that it flushes the _restore archive and whilst that removes any virus remnants it also removes any good usable checkpoints you might have and you never know when you might want to use that lifebelt. If you really are worried about this, then there are two approaches to resolving your problem: Firstly try reducing the space allocated to the System Restore archive as this could flush out these unwanted files. Do this using the slider found at System | Performance | File System | Hard Disk and reduce the allocated space until you flush out the unwanted files. If that fails, reset System Resto System | Performance | File System | Troubleshooting and check "Disable System Restore", Apply and IMMEDIATELY reboot. This will flush you restore folder and erase all checkpoints, then, System | Performance | File System | Troubleshooting and uncheck "Disable System Restore", Apply and again IMMEDIATELY reboot. This should now automatically create a new checkpoint immediately following the restart. Finally adjust the space allocated to the restore folder, System | Performance | File System | Hard Disk and adjust the restore slider to your preferred setting. A figure of 200MB is normally more than adequate for day to day use allowing perhaps a week of checkpoints to be available although increasing this to perhaps 400-500MB for a few days during periods of large installs such Microsoft Office is advisable.

If you do want to clear this folder I wouldn't advise doing so until _after_ you have thoroughly cleaned your system and got it working again just in case you need to use system restore. Once your system is clean and fully functional you can clear the folder. Moving on yo how to clear the archive.
