Good Anti-virus Software for Free

Well everyone has shelled out their hard earned cash on a antivirus product at some time or another. Well no need to do that any longer there are many free options out there these days

avg for instance

and MS security essentials

I personally use and recommend MS security essentials for simple reasoning. MS makes it so there is a much slimmer chance of problems between os and antivirus as well as windows performance degradation due to Anti-virus activities. If you have ever worked or used a machine running the full Symantec or mcafee security suites you know what a performance hit a machine can take from such products. and you get the added bunus of paying 50 dollars or so a year to have your machine take said performance hit.
