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.

Its good to run two anti-spywares even if some extra resources are taken.
SuperAntiSpyware does an excellent job. AVG’s full version gets great reviews.

Anti-Spyware for a cost.
Personally I bought Webroot’s Spysweeper, their product is great and well worth the money. Watch Best Buy ads because sometimes it goes on sale for $10 to $15.

There are free anti-virus scanners availble. They work well. I like AVG and PCTools anti-viruses the best of the free anti-virus programs.
If you are not willing to spend money it is good to have some kind of anti-virus software

This is my recommendation for anti-virus. Free are good, but they are not as accurate as the top paid anti-virus software

Kasperskyhttp://www.kasepersky.com

Spy-bot. I have a free version on my computer. Send me a message if you want it although I’m not sure that I can send it to you…but I might be able to tell you how to get it after I talk to my boyfriend (I’m not gonna waste my time though if you don’t want it). It’s some of the best stuff out there….also there is something called X-Clean (i think) it’s also free….and it does an awesome job. It takes care of more than just spyware…but I definitely recommend using both spybot and xclean.
My boyfriend got me these and I haven’t had a problem since.

Yep, check out the links below.
