It seems I have picked up the same malware discussed in the following thread, “Ping.exe and av security 2012 [Solved]”. In additional I am seeing suspicious behavior such as my CPU being pegged in my tray icon, but the process is not visible in Task Manager. I downloaded combo fix and followed the direction found in the aforementioned post; however, it complained that avast was still running even after I shutdown all my Shields. It ran all night and never completed.
Please help!

My laptop has been out of commission and would not start up. I had to do a System Restore to the Jan9 restore point. I have now been able to run the procedures up through the execution of aswMBR. I have not yet run RogueKiller or the farbar service scanner. I have attached the logs from the other scans. I am hoping that the one detected item in the Malwarebytes log was the culprit. As I am typing this message, I have not seen the “Malicious URL blocked” message that was very frequent before.
Looks like combofix got it all no visible remnants ;D
