LANDesk Antivirus keeps repeatedly popping up messages that it is quarantining files, or restoring files from quarantine such as the following:
"<File> has been restored from quarantine and renamed because the file already exists"
The number in the file keeps incrementing.
Turn off System Restore on the computers that are running Antivirus.
For additional information regarding System Restore, including how to disable it, see this article.
