If you know your PC to be clean and working well, do this:
Run HijackThis, select 'Do a system scan and save a log file'. When Notepad opens, do Save As and name the file 'KnownGoodHijackThis.log'.

Then later, for a quick malware check: First save a new HijackThis log.

Do Start->Run, enter cmd and click OK.
In the cmd window that opens, cd to the folder that contains your HijackThis logs. Usually the command will be cd C:\"Program Files"\HijackThis
Then enter this: fc HijackThis.log KnownGoodHijackThis.log > comparison.txt
Enter type comparison.txt or open comparison.txt in Notepad.
That will show you what has changed.

This will not catch the newer, much trickier malware infections and is just a quick check for the obvious. If someone is helping you with an infection, it may be useful to post comparison.txt.

Thanks, this will help me remove this fresh virus I think I got.

Sweet, I am clean. Thanks Cnm! :-D

As noted above, an identical compare doesn't guarantee that you are clean. Some of the newer infections won't be caught this way. You should scan with MBAM.
