question about deleting computer virus's

Up until now my Norton AntiVirus has been deleting virus’s when I want it too. Its not now. I know you have to look up the virus and delete it that way or something (believe I’ve done it before but I forgot). But do I just go to google and type in the virus name or something?

You could go to symantec.com and use their seach engine. That way you’d be searching in their database only.

Thank you.
