Best antivirus software?

[Noob334]

I do some work for my mom who is the owner of a Tax Company. Until this year, I have never had to have the computers with all of the clients information hooked up to the internet. The computers do not have wireless cards and I do not plug them into anything other then battery back-ups and the printers. This year the company that we get our software from is releasing the updates on the internet and I need to download them. My mom (and I) would feel better if I have anti-virus protection on the computers. Both run windows XP and are fairly new computers. One is an AMD anthlon 3400+ processer and the other is a Pentium 4, 3.20GHZ with 512 Ram. I would rather attach the Pentium 4 to the internet and then just copy and paste the files that are needed to the other. I know a little about computers but would like opions on what anti-virus software I should use as it is not only my information that is being protected. The computers would only be hooked up to the internet for a little time as was needed to download the updates. They are only supposed to be 100MB updates at the largest. Thanks very much for your help.

If you don't mind paying for AV, two of the best AV products I have found are Kaspersky and NOD32 . The edge would probably go to NOD32, but both are the cream of the crop. You can't go wrong with one of those.

Thanks a million

You're welcome!

You should also consider a good firewall, if you haven't already. Perhaps try an integrated security suite such as Kaspersky Internet Security 6.0 with both AV and Firewall.
Heck, the free trial period ought to be plenty long enough to serve your purpose. . . .

I put Zone Alarm on the computer when I knew that it had to go on the internet I was told that it was a good firewall and after reading your link about prevent malware and what not, it seems that I should be in good shape. Thanks for the advice.

Noob, remember, computer security fails always due to the weakest link.
The weakest link is commonly found between the keyboard and the chair!
