Title: SUSPICIOUS FILES FOUND (HEURISTIC METHOD) HOW DO I SEND
Post by: Nise5280 on May 15, 2011, 06:07:02 PM
I rec'd a msg. box that said avast! found suspicious files during background heuristic method scan...these files have the word DRIVERS in file name. I looked for a way to say 'yes' to sending them to avast! lab, but the only options are 'ignore' and 'delete'. ALSO, is it safe to delete files with related to DRIVERS?? I am no tech and dont want to do damage I can't reverse please. Thank you!  Nise 5280

Sounds like the anti-rootkit scan, does the image look like the one attached ?

Whatever you do don't rush to deletion, post the details about the alert as essexboy asks and we can be more detailed in our advice.

Also see the current thread here (http://forum.avast.com/index.php?topic=78198.0), where I ran into the same thing and there's good discussion of it.

I thank you guys for the quick reply. Yes, the msg looks exactly like the example DavidR posted in his reply. For Essexboy, here are the file names as they are listed in the msg box FROM TODAY:
\SystemRoot\system32\DRIVERS\ivm.sys
\SystemRoot\system32\DRIVERS\R3dne2000.sys
\??\C:\WINDOWS\system32\vsdatant.sys
THIS IS THE MSG BOX FROM SATURDAY 5-14:
\SystemRoot\system32\DRIVERS\ivm.sys
    "           "    DRIVERS\R3dne2000.sys
    "           "    DRIVERS\ivm.sys
     "          "    DRIVERS\R3dne2000.sys
\??\C:\WINDOWS\system32\vsdatant.sys
I thank you for the assistance - and no worries regarding that quick-delete...I dont go near anything with the words
"registry" or "drivers" in them without help.  Nise5280

MikeBCda - Thank you for the link you provided. I also had nothing come up on any scan, and cant find any information in my avast program. I did learn some useful things from your link; but it's a bit out of my range (I still haven't figured out what a rootkit is). Thank you again!  Nise5280

One user (sorry, forget who) noted over in that other thread that this seems to happen about once a year on average, and is merely a glitch in the rootkit scanner.  For any given user the specific file warned of seems to be more or less random, so it's not a FP problem. It does, however, seem to be particularly sensitive to drivers (.sys files) for some reason.

While it's remotely possible, of course, that you really did pick up an "iffy" driver somewhere, you can almost certainly ignore these warnings.
