Four viruses have suddenly appeared.... that I know of. hldrrr.exe, flec006.exe, wintems.exe and mdelk.exe. Messages apear from a "program not being a valid win32 app" to failure to start in "safemode" to mention a few. My virus program will catch these files and delete same. Problem is when I think things are going good they reappear. CPU usage will go to 100% with little or no activity. Have used several pgms to find and delete these buggers but they come back. I have reinstalled XP but something sneaks by. Any help. Thanks.
