Last week when I came home Norton Tools left a message on my screen saying that it had located a backdoor hack on my computer but couldn't do anything until I updated my software. Funny thing is I was running the most current version, I proceeded to download the newest updates from their website but have been unable to find that error again or any viruses on my computer.

I ran updated Norton, and Adaware. I am planning on installing a new hard drive and copying over some data and a lot of programs. I think this backdoor may be linked to my IRC software and such.

My basic question is if anyone knows of a program or where I can look to locate this backdoor hack that is in my software somewhere. Please help a geek in need
