pprekop.exe / killing Comodo / BSOD's ?

Something has been causing more than its fair share of instabilities, BSODs and Comodo crashes on my machine. This time I think I caught it, something called ppkerop.exe. This file does not exist locally. There is no .dmp or Dr Watson. There is much chatter online about the same problem, but no answers or acknowledgment by Party Poker (who’s users I assume are the target) -

Culprit doing it (in this case) -

Whether its mere coincidence, or work of the devil, I have also started noticing a much higher frequency of SQL port probes at the same time.

Has anyone experienced this or heard anything about it ? My system hasn’t actually been penetrated that I know of, but it has been killed dead. Repeatedly. I’ve run multiple rootkit / malware scanners. Nothing. Log atached - pprekop.rar

Sure looks like a rootkit nasty …

I think your best bet is to post this at http://www.castlecops.com/f233-Rootkit_Revelations.html

I've run multiple rootkit / malware scanners. Nothing.

Seems the consensus is that RootKitUnhooker, GMER, and RootKitRevealer are the top scanners. I’d suggest trying all 3. software AVG Antirootkit – Rootkit Trends & Prevention Blog

Edit: these tools are potentially dangerous. Do not use any of them unless you know what you’re doing.

Thanks. I’m trying several angles of investigation as it has my curiosity piqued. The sysinternals scanner found nothing.

My primary concern is that the incoming rpc call brought Comodo down - thats why I posted here. And that’s in the rare instance that it intervenes before a BSOD.

Heh, this is the 3rd robotic response I’ve received from Party Poker -
