FIXED: VPS 170222-0 is already out and fixes this false positive. Moroni





UPDATE: This False Positive detection should be fixed very soon with a new vps update. Moroni



Today i had 2 virus alerts from safe sites. One was xchat.cz and second on google.cz What happens? Cant belive this is real virus. Thanks

UPDATE: Not only those sites! Also if i run FULL SCAN, thousands of files are detected as virus! Can u imagine what happen if some user delete those files and no more boot up PC? This is unacceptable! Thank you avast. This is not first time i see that huge mistake in your products.

UPDATE 2: Thanks for fix, everything is ok now.

Same here.  Repost from my other reply:


I'm getting all sorts of hits on my computer and VM today with Avast warning me about a generic "VBS:Malware-gen" when I open Google Chrome.   I ran a "Full system scan" and I'm at 1,000+ hits and counting, and my drives are only about 24% scan completed).  The irony is Avast's "Smart scan" detects nothing, but the "Full system scan" does.  What good is it if it can't detect jack?

I ran online scans from ESET, Trend Micro, Kaspersky, and F-Secure and they all came back negative.

I use Macrium Reflect to back up my system so I restored a full image from about 2 weeks ago (errors only started today), and Avast is complaining about files being infected from this restore too.

I powered up my laptop (which I haven't used for months) and updated Avast's antivirus definitions and ran a Full system scan on there.  It's also detecting the SAME THING.

I'm going to restore my system to about 2 years ago to see if Avast still detects it too.

The last time Avast reported false positives was a few years ago.  n00bishly, I let Avast delete my Windows system files and had to do a complete reinstall of Windows.

Is anyone else running into this same problem????

I get an alert about google chrome about every 5 or so minutes, and i got one from twitch earlier. I'm running a full scan now and it says theres infected files but I don't think they are?

I'll upload a screenshot when i get another chrome one.

No biggy, everyone using avast right now may have random report, using their browser. May be fix later today, i guess.

I'm also getting this exact problem on random websites I go to, roughly every five minutes. I scanned my computer with avast, roguekiller, malwarebytes and several others and none found anything either.

I'm on a Mac and today I am getting a similar result - 500+ "VBS:Malware-gen" identifications and the deep scan is only 50% done.

Sounds like this is some kind of erroneous detection going on today.
