Avast causes massive outbreak with False positive: Win32:Kryptik-PFA

Avast updated a definition on on 05 - 06 May 2015 which have affected most games, businesses and education centers which had an Avast version running.

 

The primary cause being "False positive" disguised as Win32:Kryptik-PFA which infects installations, DLL's and Graphic card/video drivers except that it didn't.  

 

Basically everything important might or might not work anymore because few of its DLL's or important files are missing from the location and have been quarantined in Avast.

 

Suggest not just uninstalling Avast right away but first getting your files out of its quarantine (restored) after you disable avast. (else it will re-quarantine them on next restart or immediately)

well thats certainly an issue, i imagine some of my friends are going to ask me about this.

[Atmos]

Yup, this is confirmed. Just finished actually walking my friend through uninstalling avast because it did this to him. My avast hasn't flipped ape-shit on me yet, but that's because i have my virus database on manual update.

 

Programs I know are being affected by this,

Steam.exe apparently just the exe,

Geforce Experience

Origin

Nexus Mod Manager

Battle.net

Battlelog

 

Those are all the false positives that came up in his system, well the most common ones.

Just turning off file system shield seems to avoid the issue. That is what I did, and hopefully, I can turn it back on tomorrow when I get back on my PC.

People are only mentioning Nvidia drivers, is AMD affected?

 

And I literally just ordered a 970 a few hours ago, lol.

 

EDIT: tag me when they have release a safe update, I am going to get off my PC, so I can't exactly monitor.

[TheKDub]

Hmm, guess ill go to manual updates for a bit.

[spartaman64]

? my avast is up to date and everything seems to be running fine

[CommandMan7]

literally updated and restarted avast 15 minutes ago and it seems fine.

[VerticalDiscussions]

My avast good so far so i did not get any false positive :l. I hope for the BUST.

[Burusutazu]

Whitelist the files and you can continue using the antivirus, I got a false positive for GTAV's updated launcher.

[Uwillparish]

*looks at taskbar* Sweet, no avast here, might want to notify my brother-in-law though of this, i think he has avast

[Snadzies]

No issues as of yet but it is good to know in case something comes up.

[Thony]

I think my avast is on manual update for software version. Not sure about the database but so far I haven't had any issues.

Will definitely check and possibly change database updates to manual.

Guess I will try different AV when I reinstall my OS for Windows 10.

Ive seen avast web shield claim this very website is infected by a virus on two different machines....while i dont mind avast its web shield is obnoxiously easy to trigger on some sites

[projectHades]

This happened to me, unfortunately i uninstalled avast and it broke my laptop, over 400 gigs of data lost......on a plus side backed up some of it

[Theminecraftaddict555]

Nothing happened to my computer yet...Lets hope the issue doesn't pop up

[awesomes8wc3]

ussse bitttdefenderrrrrrrrrr

[Pesmerga]

Sad, I liked avast but had to unistall it because it made my pc bluescreen, even microsft answers suggested me to remove the antivurs and roll with the one integrated in windows 8.1 :c

[Thony]

I disabled updates untill this gets resolved. Otherwise i have to reinstall my OS (oh pls no, cba !).
