I have noticed that when looking at my processes directly after boot, I see NetTsk.exe. I can't seem to get any results when searching Yahoo for this process, however, all of the others return results.

I have scanned with Ad Ware, Spybot, Registry Mechanic and various "online" scans. Nothing shows anything negative, however when I don't end this process it jacks my CPU usage up into the 90's and lags my system badly.

If someone could please explain exactly what NetTsk.exe is, it would be greatly appreciated.

Thanks in Advance

First please get Spybot S&D to clear out most of the spyware.

Short tutorial and download link here:
http://tomcoyote.org/SPYBOT/

Fix everything SpybotSD labels in red.

Then after reboot:
Download 'Hijack This!'. http://www.tomcoyote.org/hjt/
Unzip to a permanent folder, doubleclick HijackThis.exe, and hit "Scan".

When the scan is finished, the "Scan" button will change into a "Save Log" button.
Press that, save the log, load it in Notepad, and copy its contents here. Most of what it lists will be harmless or even essential, don't fix anything yet.
then post the log here

Thanks for the reply Caper. Below is a copy of the log file.

After following links in your sig, I went to Trend and did a scan. http://www.digital-accents.com/bad_stuff.JPG

I think you should add this to your signature.

Hint: Harden IE and you would not be this situation.

perhaps you can tell people how to harden IE ,I have this in my signature
How I got infected in the first place

It is something I tell people to do as you can see from the first post i made .

If you ran the virus scan after the hijack log was created please run hijak and post a new log .yhanks
Also you have hijackthis.exe in E:\ hijack, is E a second harddrive .

I agee ,thanks for those who use the programs in my sig, without asking questions first ,Done
