Pros: As far as its effectiveness, the Kasperski brand name speaks for itself, so I really don't need to add to that, but I will chime in about the low footprint it takes/consumes on system resource. This product is fantastic!!

Cons: Even though I am an IT professional, I'll have to say I had a little bit of a problem setting up the auto scan (both Full and Quick). It wasn't as intuitive as one would think, but I figured it out.
