Kryptik-PFA [Trj]
« on: May 06, 2015, 08:28:38 PM »
Users all over my network are getting infection alerts for Kryptik-PFA [Trj] after the latest 150506-3 update.  I think it's a massive false-positive reaction.  Can anyone confirm and fix on the next update?

We're seeing a major uptick in notifications for this virus too.

Can you change your group settings to 'no action' for now?

We're seeing this in our school district, too. We're getting hits on 32-bit and 64-bit Windows 7 Professional.

We're getting false positives on "C:\windows\system32\MBWrp32.dll" mainly. I sent that file off to VirusTotal and got this back:

https://www.virustotal.com/en/file/8f9234b7efd9e06430c79615a3491f59e105622ad439db3042364ebbb0554e43/analysis/

We gotten a couple hits on "C:\Program Files\Google\Chrome\Application\39.0.2171.95\libglesv2.dll", too.

It sure looks like a false positive. I threw on a couple of exclusions to try and stem the tide.

Anybody know if there's an API that I can use to connect to the "Virus Chest" on a hundred PCs to restore this file, or am I better off just copying it with a script?

Edit:

It looks like this is going to be a chance to exercise an "Auxiliary Task" to restore previously-detected files from the "Virus Chest" that are no longer detected *once* Avast updates the definitions.  >sigh<

Same here. Different files, machines all over the network.  Virustotal shows the files are clean, even by Avast.

Do you have a 'How to' on that? :)
