If you want good program, good antivirus then i suggest you to use F-Secure. I use it and it helps also block internet virus sites and scam sites. Good way is that you can downcrease or upcrease put the virus detection level, so it don't whine about hacks and all that shit. It haves too it own firewall and other important stuff. So it costs, but it's good. I am not sure can you download it from piratebay or somewhere but i don't trust them as virus detection applications. So if you don't have enaught pocket money or your parents saying "fuck you, you can squeeze that antivirus in you ass." then i am saying download avast
