I need to add an Anti-Virus to my PC but I don't know which to add. I need suggestions.
I've been using the latest builds of AVG ever since I got my laptop here back in July of 2009 and I haven't encountered a single virus. A couple of trojans, yes, but a quick scan pretty much gets rid of all of them. So I recommend that (since it seems to be working like a charm for me).
I also use AVG in conjunction with Malwarebytes Anti-Malware, because I encountered a "virus" back on my desktop that no AV program could get rid of and Malwarebytes was the only thing that would actually dispose of it. So yeah, if you won't get AVG make sure to download Malwarebytes incase the same thing happens to you.
