Win32:Kryptik-PFA [Trj] - False Positive ?
« on: May 06, 2015, 08:56:43 PM »
Hi,

My File System Shield as started moving files to my chest this afternoon.
Most notably my Lightshot.exe program that allows me to do screenshots.

When I scan with Avast I get 256 infected files.
MBAM does not find anything.
SAS does not find anything.

They cannot be repaired.

When trying to reinstall Lightshot, it blocks it.
Here is the screenshot :

I am having this same issue as of 1330 CST, Brand new computer reporting this Trojan in the Gobi wireless software on an Lenovo X1 Carbon. Definitely a false positive, need it fixed too.

if you think so, right click file(s) in chest and report to avast lab as FP
Chief Wiggum: Uh, no, you got the wrong number. This is 9-1…2.

I have two computers that just started showing this same issue with the business edition.  I have submitted a file from TortoiseGit that was showing as being infected.

We also are having a wide spread report of this happening on our college campus. It seems like it started at the same time the latest definition came out. Thinking a bad set of updates are the cause.

Same is happening to us. First report was at 11:49am PDT. I'm getting multiple notifications reporting various files as infected by Kryptik-PFA. Most of the reports are saying that it's our KACE KDeploy.exe agent that is infected.

Definitely looks like a bad definition update.

We even called Avast and we were told they can't help us and we need to submit a ticket. We said we think it is due to the update and its a false positive and they said then you can write a exclude statement for it. Since it is flagging tons of files, that would be a endless battle. If you guys have not created a ticket yet, I would suggest putting one in so we can have extra pressure for them to fix the latest batch of updates.

Same version here also:  150506-3  Anyone come up with anything besides adding exclusions, which as was posted is an endless battle because its different files on each machine.

Oh good, it's not just us :P

We're getting it on dozens of machines and hundreds of files as well, so excluding or reporting the files will do no good. I have a feeling that cleaning up after this false positive will be more work than cleaning up an actual trojan...

Having the same issue here.   Dozens of files are flagged.  Happened soon after today's update.
