Un4g1v3n,

I don't see anything bad in your log so lets see what is being run at startup:

Start HijackThis and click the "Open the misc tools section: now put a check next to "List all minor sections (full)" and then click the Generate Startuplog list button :
When it is finished a notepad window will open, copy the contents of notepad into your reply to this thread.

Also your windows needs to be updated to service pack 2!
Please go and update your windows.
(note you must use Internet Explorer to access Microsoft's update)

If you can't download SP2 from Microsoft Update, you can order it on CD from

In that case Microsoft has a security update that will protect you until you can install service pack 2

Un4g1v3n,

That log is clean too

You could have a rootkit there are more of them out there now and without sp2 you are vulnerable.
Please download

Extract RootkitRevealer to your root like this C:\RkR\ RootkitRevealer.exe

Close all other programs, windows and disable your screen saves before you start RootkitRevealer.
While RootkitRevealer is running, you shouldn't do anything at all with the PC.
Put down the mouse, back away slowly, and let the program do its work.

Start RootkitRevealer and press the Scan button.
It will take some time to finish an hour is common so just wait it out.
Once the scanning is finished RootkitRevealer will create a log, please copy the contents of that log into you reply.
