When it comes to the big issue of spyware/adware infecting my computer, I have found that some things snuck through both Ad-aware and Spybot S&D. Which is why I started using HijackThis, and I've found it, with the help of some basic instincts and the help of a few computer-pros, to have helped me get rid of several un-wanted objects. I run a check every now and then, and so my Windows system (I'm currently on Linux) is completely spyware free!

Any other HijackThis users around here?
