So, I'm using the Mcafee that came with my Cox subscription, And I just got back from a fresh install of vista home premium 64 bit, And all of a sudden (Like starting today it seems) My anti virus and firewall just disables itself once every couple of hours or so and I have to reenable it manualy. It seems to work fine but just that. It did not do this on my old install of WIndows, And I have had the same thing. What could be the problem? Mcafee says I have no viruses, And Virtual tech support or whatever it is reported no problem. I also have that User Account Control enabled which seems to cause some problems. Could that be it?
