Hi Kevin.....i have a desktop, and on the latest edition of pc advisor..there is a program called Kaspersky internet security 6.0. Peronally i'd say this application is SUPERB, as it incorporates a firewall, anti virus, spyware ect, all in the package. Its totally free for 6 months...and u have access for that period. Its very light on pc memory, but u'll be blown away. I also use AVG version 7.5 which is also free. So i'd say u shoud try both of these and u'll be fine.
