I've read Julio's post and I've completed all the steps. My computer, as of 2 days ago, started running extremely slow. I was only able to notice the difference while playing games or watching HD quality videos. My friend pointed out that "winlogon.exe" was consuming roughly 50% of my CPU. I found this site and I went through the 15 step process. I'm running Windows XP SP2 with a P4 2.8 HT processor and 1.5GB of RAM. I have the 3 logs: HJT, Combofix and SAS, but I won't post them until told to do so. The Panda Antirootkit scan turned up nothing. Any help would be great. Thanks in advance.
