So far, Vipre has found these downloaders using the Active Protection, not as part of the nightly scan. That's no guarantee that it will continue to find them, but I'm hopeful that it will. J

I know of no AV product which scans an NTUSER.DAT file. If the user associated with this file is logged in, then it is scanned as a part of the active registry. If the associated user is logged off, then scans do not find the ugly things hidden in HK_Current_User\Software hives. (Perhaps this painful, irritating nature is why they are called "hives"!) I've found all kinds of crud either as major hives, or I've found things in .\Microsoft\Windows\CurrentVersion\Run (which, again, show only when that user is logged in). 2. I found a really nasty one a couple of months ago that VIPRE missed. (It now finds this, BTW.) Look in the \Windows, the \Windows\System, and the \Windows\System32 folders for recent files, especially DLL, COM, or EXE files with weird names (randon string of letters). Both #1 and #2 (as well as numerous others) will stay kind-of hidden but continue to download crud. The AV scans find what the malware downloads, but they miss the downloaders. -- Richard D.
