I have a Win XP Pro PC that has gotten an infection that I cannot get rid of. I have ran Combofix, MS malicious software removal tool and Malwarebytes to locate and get rid of it but I haven't been successful. Malwarebytes has removed some things but my symptoms still exist.

Symptoms:

1. svchost is taking up 85% cpu and causing pc to come to a halt. Process explorer shows 5 instances of svchost but it is the svchost with the child process for windows update running under it that chews up cpu cycles. Command line shows the -k netsvcs switch.
If I kill the process the PC runs fine but the svchost process begins again after several minutes and I haven't narrowed down what triggers it.

2. the browser is consistently redirected. I can go to google.com but when I click on a result I am redirected to ad pages.
The proxy server section of the IE connection tab is clear.
There is no host file under c:\windows\system32\drivers\etc
I downloaded G-Chrome browser to use while IE was hosed but it gets redirected also.

Note: I have GFI's Management client (Advanced Monitoring Agent), GFI's managed antivirus(Vipre), and Teamviewer on this PC
I have disabled all startup items using MSconfig

Here is my hjthis log:

Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.
