So, I ended up getting caught by the Security Essentials 2010 virus. Ran MalwareBytes and it cleared out a big mess of crap. Avast! Also caught it and blocked the rootkits.

Right after getting it all cleared up I noticed my computer was still acting extremely funny. I open up the Task Manager to see how many processes were running and noticed that my CPU usage was at 100%. Normally it'll fluctuate and dip back down to 0-45%. This time, I noticed it was running at 100% constantly. Even after I disabled all my startup processes.

I even tried a system restore to a point last week just to be cautious. This turned up to be a whole new issue. After the XP loading screen it would turn to black and a BSOD popped up with a stop error. It was a Bad_Pool_Header 0x00000019. The parameters weren't always the same either [in the ( )'s].

System specs:
Windows XP Home SP3
AMD Athlon 64 3000+
2.01 GHz
1 GB of RAM

I can provide a HijackThis log upon request.

I'm not infected, at least as far as I'm aware. MalwareBytes and Avast have not picked any other threats up since the removal of the Security Essentials 2010 virus. All this is from after the removal, and cleaning out of known malware threats. This is a problem that seems more like data corruption or memory leaks than malware.

Actions taken thus far to remedy this problem:
MalwareBytes Full Scan
Avast! full scan
Checkdisk scan
System restore
Defrag
CCleaner

Hello,

You mentioned rootkits. I suspect your issues are caused by remnants of the infection. Please follow the instructions in ==>This Guide<==.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<==

If you are able to produce at least some of the logs, please post the new topic. If you cannot produce any of the logs, then post back here and we will provide you with further instructions.
