Thought I would do a quick SpyZooka review.
However, I am going to keep this really simple. SpyZooka costs money... SpyZooka is an anti-spyware program. Many of the top anti-spyware programs don't cost money. So to spend money on SpyZooka, there's going to have to be something spectacular with it for me to buy it. So is there anything spectacular? I sure didn't see anything spectacular with SpyZooka. In fact, the detection is just average at best.
My advice? Download a free scanner like Ad-Aware, and use the money you considered for SpyZooka to buy Registry Winner. It's got a lot of tools that will help in speeding up your computer, it will do a lot more then SpyZooka could ever do.
