If you still want/need an antivirus program Deacon, I would suggest Avira Antivirus, they have an awesome free version. I have used it for 2 years on all 4 of my PC's (2 of which anyone that comes to my house can use) and not had a single virus on any machine, it does real time scanning. Say if you visit a page that contains an infected script, before running said script Avira will say hey do you want to delete this, quarantine, or select no action. Its saved my father in law from his usual monthly virus attack for over a year : ) Only catch is the free version has a popup that offers cheaper price on the full version when the antivirus updates the popop comes up (once a day depending on update settings) If you google "Disable Avnotify.exe" you can find instructions on how to remove the popup its pretty easy about 10 mins work for a nice antivirus program.
