Had a customer whos machine was running slow. We ran WinDirStat to see what was eating up the space on the machine. The pagesys file was huge, but a large chunk was under VIPRE. Specifically with the PatchManagement Patches.
According to VIPRE is it okay to delete out the contents of this folder. We found this information here.
Deleting the files went fine. We left the small .pup files since they were small.
Let us know if this helped you.
