Long story short
I just signed up for the AT&T Uverse bundle (friggin excellent btw). Anyway the wireless internet comes with Mcafee so when I bought my new PC I didn't need antivirus. I get home and find out that Mcafee is not compatible with Windows EX8. So i decide that I will load the 2 months free of Norton that the comp comes with till I can get a something better. I proceed to install and all is well. I turn off the comp, wife gets on and the PC starts to freeze and then just stops, mind you I have had it for 2 hours. I end up having to wipe the PC clean and uninstall the Norton and install Kaspersky, haven't had n issue yet.
