What I've noticed is old virus/trojans rarely make the rounds. It's the newer items you need protection for.
Since this is not exactly a XP issue, be sure to note your Antivirus issue in the Security forum.
In closing, not all websites work with Mozilla/firefox. For those I use IE.
Im running SP2, ZA, Webroot spysweeper, AVG , and Mcafee Virus scan. My question is __ Should I need to keep Mcafee virus scan even though I am not getting the auto updates because I have stopped using I/E and switched to Mozilla firefox. If want to get the update I need to first unblock I/E then go to Mcafee website and open my account then click on my products, then install/update and then the updates are installed , this is crazy! Is there a plug in or something I can get for M/F?
Any help would be appreciated, Thanks!
