Best overall computer security program?

Hi,

I had a major computer problem a few days ago, and I had to reformat my computer. I was using AVG Free Edition to protect my computer, but it didn’t detect a virus that came on my computer and made a lot of things unaccessible.

I’m now using Avast! Professional, and was wondering what was the best all round security program, including internet security that stops unwanted software installing itself etc.

Thanks.

How can I remove the Security System on my computer?

I let a guy who thought he knew what he was doing put an anti-virus software on my computer, but instead it was an actual virus. Now my computer runs really slow and shuts down on its own after being on it for a while. But i need to know what I can do because i start up school on Monday and if my computer is all jacked up I can’t.. HELP!

How do I get Vista Home Security off of my computer?

It won’t allow me to open even Firefox or Internet Explorer and it is extremely frustrating. But remember that I cannot access the internet because Vista Home Security won’t allow me.
