  1. Hey Guys,

    My pc been infected by Virtumonde and ad popups for the last few days. Symptoms include, browser (Firefox) extremely slow to load web pages as well random ad popups. Also Spybot picked up Virtumonde and tried removing it bit it wasn't successfully. Also my pc CPU was running at 100% most of the time with winlogin.exe taking almost 50%f the cpu usage which is unusual.
    I ran HijackThis and here are the log files.... Any help is greatly appreciated.
