I'm helping my Dad with his pc, he insists on keeping his old WinXP box. ( I have tried to explain the problems and potential security threats ) I have even given him an old pc I have with Linux on it ( can't afford a windows license ), and walked him through how to use it, but he is just not getting it.
so I was wondering, has anyone used a VERY small footprint antivirus program that is pretty good, and preferably free?
I need something that won't take up a lot of resources, since his pc pratically has none. I don't remember what the processor is, but it only have 512mb of ram. There is plenty of hard drive space.
