Well about 4 months ago I was very nieve and believed that the copy of CA on my computer blocked every virus known to man. (Laugh, I know it sounds stupid) That was until I started learning about viruses and I meet people who felt exactly the way I did.

As for virus protection I would suggest AVG Free 9.0 and to install Spybot S&D as well as Malwarebytes. Immunization works great and AVG's toolbar has little
flaws. (It has some) However, formatting doesn't always work for many viruses will stay on your system even after System Restore or formatting.
