Avast acting weird!!help..

this morning a friend of mine ask for help because he..just notice their antivirus w/c was Avast (home edition)..because they dont have internet connections,was acting weird :

il upload the pictures later Please check it out..

when he checked his Avast virus chest his some unused>nvidia files sumthing like that (3dvision.exe) were put to virus chest,theme generators and even some adobe reader components (.exe)...i scanned them one by one..and the result is --no virus-- then i tried to restore it,but it cant. .and when i open its folder directory.the avast will beep and beep..and will say "virus has been detected"..more than 30 times. .

What is wrong with this ??!

Download, install, update and run a full scan with Malwarebytes.

If nothing is found, you can uninstall Avast and replace it with comparable Microsoft Security Essentials, then Run a full scan with it.

but how can i restore the files back??it seems its not working..

Now look at this photos!! im still going on about your suggestions :

you can see those are obviously not virus..or malware,trojan,worms etc. .i scanned them all one by one..

Respectfully, I'd suggest you will be better off using Avast's own removal tool rather than any third party solution...

aswClear

--also contains directions to be executed in SafeMode.

or, for better exposure post "also" in the avast forums. The developers there would love to hear this one plus you can learn more "how to use avast". As for the files(encountered some nvidia/adobe files wanting to make a hook through .dll's --which seems to be corrupted), will be lost "if" you cannot recover it properly prior uninstall. A re-installation of the main nVidia driver package and the Adobe package looms.

Your screenshots are blank except the "German Sheperd Dog Licking Screen Cleaner.exe" which is clearly a Win32FileInfector there as detected by avast. Can also be an FP. So you better check it via VT/Jotti/Filterbit.

theme generators and even some adobe reader components (.exe)...i scanned them one by one..and the result is --no virus-- then i tried to restore it,but it cant. .and when i open its folder directory.the avast will beep and beep..and will say "virus has been detected"..more than 30 times. .

Where is the scan result or image/screenshot that says, that the files are "clean" and "--no virus--" as you state? That "German Sheperd Dog Licking Screen Cleaner.exe" may be a variant of those 2007 dog-licking-screensaver with embedded trojan affecting display functions(may have very well corrupted the nVidia driver package and Adobe Flash). Kinda/seems like rootkit behavior there and Avast is trying to block it(having a hard time also it seems). MBAM scan will be nice(as gregrocker suggested).

You can send the samples(including the "German Sheperd Dog Licking Screen Cleaner.exe" ) to avast for verification and some copies to VirusTotal/Jotti/Filterbit.

By any chance did you happen to click "Add the file to the scan exclusion list" in the pop-up for the "--no virus--" files you stated?



It's on you what steps you will take. Goodluck.

Try to repair it before uninstalling it. See below.
