Adaware and spybot rarely if ever find the real culprit. If I have odd [censored] on adaware or spybot then I know I have something. Once a week I'll start in safe mode (keep pressing F8 on startup) with networking and run two online scanners. The links are below. You may also want to browse the forum I'm linking below. One sticky says "How to Protect yourself from malware" and the other says "READ & RUN ME FIRST. Malware Removal Guide" Most if not all the programs in there are free. I have never found a virus or other [censored] that I couldn't remove following their advice in those two threads. Before I started playing poker, I used to download stupid [censored] intentionally. Always cleaned well. Once I had to run in Windows recovery mode and run a program to check for text in a file. The file I couldn't access was the virus. This file was invisible to the windows operating system. That was the toughest thing I ever ran into. The site below helped me to remove it.
Also +1 on the Zone Alarm. You can leave it on the higher settings and see virtually every program communication coming in or out of your computer.
BTW, IN MY OPINION, IF YOU FOLLOW THE STEPS <u>EXACTLY</u> IN "MALWARE REMOVAL GUIDE", YOU SHOULD HAVE A CLEAN COMPUTER AFTERWARDS. I would still install and run ZoneAlarm just in case. The free version of course [img]/images/graemlins/wink.gif[/img]
Good luck
