I'm not sure where to start.

I have 3 networked home PC's. My personal (main) PC started to get BSOD at least daily. I decided to reformat and reinstall everything since I believe this to be good housekeeping at least yearly. Anyhow, after reinstalling, I got frequent slowdowns. I also had problems running Zonealarm 6 (true vector shutdowns and Trend PC Cilling shutdown). I have now settled on AVG and zonealarm 5.5. My computers are also behind a router/firewall.

I took precautions and scanned with ewido, adware se, spybot and trend housecall. I cleaned out all the tracking cookies out but noticed that Housecall was also identifying ADW_SE and TRAK_SE as malware/greyware. A google on this got quite a few hits but no specific confirmation on whether these were a threat.

Also, I noticed processes such as svchost and spoolsv we sometimes taking up 99% of CPU resource, virtually locking up my computer (which is an Athlon 64 3000+ so it should be pretty fast). Also, downloads from the web and files transferred between my PC's were frequently being reported as corrupt, and some installation programs would hang.

Since this was a fresh install I was confused. At this stage a really dont know whether I have a software issue; driver issue; hardware issue, or if something on my own network keeps re-infecting me.

So I decided to go through the same scanning routine using ewido, adware se, spybot and trend housecall on all 3 PC's, fixing everything that was found except for ADW_SE and TRAK_SE. Another puzzling thing is that on one of my PC's trend housecall wouldnt even run.

I have a hijack this log for the 2 PC's - should I post them, or troubleshoot other things first?

Post both logs, but put them in separate threads and mark them accordingly.

Also, post a startup list from each in the respective HJT thread.

Would you please use HiJackThis to produce a startup list and post it here:
1. From HJT main screen, click 'Config' button
2. Click 'Misc Tools' button
3. Check both boxes to the right of 'Generate StartupList Log' button
4. Click 'Generate StartupList Log' button
5. Click 'Yes' in the next dialog
6. Save the log and post a copy in this thread.

It seems my problem was memory timings. I have Ballistix ram and was using 2.2.2.6.1T but when I slowed the timings down, everything was OK. The odd thing is that, while using the faster timings, memtest showed no errors after 4 hours.

Any advice is welcome.
