If you are looking for free anti-virus software, try using Avast It works well and updates automatically. I like it better than AVG; it uses less memory, has a nicer interface and is more customizable.
I am speaking from personal experience. I personally prefer Avast!. I think it's superior and updates automatically. The updates are as frequent as with any other software and it's all FREE. I really recommend it. And almost forgot to mention that all you need to do to get the key is register....and you receive it in your inbox. Good huh?
P.S.: Both are Czech, I am Czech...both are good...see the point.
Well, for example, right now some of my colleagues are running avg and they are unable to reach the virus database and have been unable to update their copies in two weeks...not very good
Well when i sawthis topic, and specially cause i was having a long startup problems, i decided to uninstall norton internet security and put avast and outpost firewall. They both are great.
