Yeah, AVG is free and not to bad.
I personally don’t even use Anti-Virus, but at the same time I don’t download a bunch of files and if I do I’m sure there safe, because of the source. I also don’t go browsing in sites that I think can be unsafe, like hack sites or other sites that might give software away. I have my mail to where it doesn’t preview any mail and I get near to no junk mail and if I got something that needed to be open I wouldn’t unless I knew them and I don’t get enough of this mail to even bother scanning. The Anti- Virus slows my mail down from opening, so I uninstalled it. I sure wouldn’t want it on while searching the net, because it will slow it down, but the fact I play games I don’t want to be bothered with turning it on/off. Besides just because you have an Anti-Virus doesn’t make you 100% safe, since you have to manually scan the file and if you go to the wrong site someone might be able to take control of your computer, plus if the virus is a new virus the Anti-Virus might not help. I think having a fire wall on and having a pop up filter are more important, but that may depend if you download a lot and where from. In my case I feel I don’t need one and you might best decide if you do. I also feel if I did get a virus I should be able to tell and do something about it then, at least I hope.
