What is "Hijackthis log"?

HijackThis is the primary tool we use to analyze what is running on a computer when trying to resolve malware infections and other problems; it was created by Merijn (http://www.spywareinfo.com/~merijn/)

There are several tutorials around (such as this one -- http://www.bleepingcomputer.com/forums/index.php?showtutorial=42), but you shouldn't use it on your own until you've learned about it from someone familiar with it.

If you wish to get it, and post a log here for assistance with it, you can get the self-extracting version from here (in line 2):

Then close any open browser windows, 'Scan and Save Log' with hijackthis, copy the log, and paste it in this thread (along with a description of any problems you're having).
