While I'm pretty well versed in the human side of this topic, I know very little when it comes to protecting computers. I had a program named "Avast" which worked pretty well, and I guess I picked it up a year ago since it's now telling me it's expired. I really don't want to pay for anything so I wondering if anyone knew any free virus protection programs available. I have always put tremendous amount of trust in the insight of the diverse Siege community, so I come to you all for your advice and wisdom. I don't want to have to abstain from using my computer in any solid capacity for much longer so any direction would be greatly appreciated.
