False positive, or Danger? Ever-changing IRP Hook detected.
« on: December 30, 2014, 08:02:11 AM »
Earlier today, MBAM caught the Poweliks trojan. I followed some instructions to remove it, mostly involving the help of RogueKiller. After it was all cleaned up and I restarted my computer, I ran a couple more scans to make sure everything was okay. I noticed RogueKiller was showing a potential IRP Hook in these later scans, but everything else showed up clean.
 
The oddity is that when I restarted my computer, the Module it was pointing at as a potential IRP Hook kept changing! I have no idea what to make of that, and no clue if I should be concerned or not. Please help me get past this worry! I've included a RogueKiller log here, though please remember it shows a different Module each time I restart.

Hello
Do you have daemon tools installed? This can cause such FPs.

Turns out I had an old version of it still installed. Removed it and restarted, but the problem persists.

Edit: Did a little more searching, found out that a certain part of Daemon Tools doesn't get removed with the uninstaller. Got rid of that and all shows clean, thank you!

It was not an obligation, just a question :)
I noticed this lines were showing with Daemon, we're still working on it to find a way to whitelist it, but that's not as easy.
