Ok as the title says, keep it simple. Been using Microsoft Security Essentials now for some time, had to admit it has let in a few things on the miss PC (she is just awful and clicks any links >.<) also i noticed today someone already posted about the AV-Test's findings. (Link to them for refreshment: http://www.av-test.org/en/tests/home...7/novdec-2012/)
All this makes me thing I should really invest in some good anti virus software. I am after something that's effective and wont slow down the computer to a crawl. Any ideas and what are you using and why?
