How do I get this malware/adware crap off my pc for free?

PCTools products do get good reviews. The good thing is they have free versions of their products. They work great. Spyware Doctor from the Google pack is a must. I highly recommend it. I bought Webroots Spysweeper and spyware doctor finds stuff spysweeper does not. Having both is a perfect combo and I recommend running two anti-spyware products.

You can do an online scan for viruses and spyware for free from the major vendors. Some of these require Internet Explorer to run because of Active-X
