I want to use my ATT Yahoo virus protection on two other computers on my home network. How do I do that?

I got this virus and when I thought I was downloading a virus protection system I got that…except it wasnt protectection. I really need to figure out how to get rid of this because SuperAntiSpyware hasnt even gotten rid of it.

I’m looking for internet access filtering and virus protection for my home network. I’m looking for a HARDWARE solution, not a software solution. So far, I’ve been able to find Phantom Technologies iBoss and Zort Lab’s netblox. Are there others out there? Does anyone know how these compare?

I have Norton Anti-virus and I update it regularly. However whenever I perform a full system scan, it never finds anything other than a cookie or two, so I don’t see the point. I regularly delete all my browsers’ caches, files, cookies, etc, so I don’t see the need for the virus protection other than needing something to automatically start and slow my computer down when I don’t want it to.

Question I guess is, do I actually need the virus protection?

We are a small firm, 10 seats, and currently use Norton Anti-Virus and are sick of it. Problems with existing applications and an administrative nightmare. What are the other options? What do other people use for virus protection? I looked at mcafee and it was even worse. What do the big boys use for virus protection? Thanks.
