webroot offering Spysweeper 2011 free for 6 months

well.........if you are interested then this is a chance to take the new SS for a spin
Webroot free for 6 months

I have tried in on Virtual Machine.
Based on that experience my personal opinion on this product isn't really good.

In my opinion there are far superior products (which are natively free not just trial) which can accomplish this task.
So, if you really need some kind of anti-spyware, I would recommend you try checking other products.
