Please download and run http://www.thespykiller.co.uk/files/HJTsetup.exe
It will install hijackthis in C:\Program Files\Hijackthis
After installation, go into that folder and run hijackthis, do a new scan, save the log, and then post the new log here.
Before we start fixing your problems, I would like to see if any other startups are involved. To do this, I need to see another type of log please. Go here
and download Silent Runners.vbs to a new folder on your Desktop (Clicking the the download link works if you use IE. If you use FireFox, rightclick on the link and choose "Save Link As") and run it. It generates a log too. It takes a minute or two and it will notify you with a popup when your log is ready (make sure you wait for the popups please) Please post the information back in this thread too (you may need to make a couple of posts). If your antivirus program queries the script, allow it to run. It's not malicious.
