I also have SP2, ZA, and AVG (Paid Version)plus a couple others, and use Firefox. I did have Norton 2003 and removed it. You have a choice, leave Mcafee on your PC as a back up, since you have AVG or remove it. I kept Norton till my year expired and then removed it. But the choice is yours to make. I'm sure you will get a lot of suggestions.
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!
