I used Norton's forever, too, until I got this computer. I installed it and everything went wonky with the computer. When we called the computer manufacturer (Dell) they said there was a "known issue" between Norton's & this particular model of computer and to switch to McAffee, which came with this computer, so I switched back to McAffee. I didn't really like it because I'd used the whole Norton's thingee with all the utilities, not just anti-virus, but now I use System Mechanic for that.

I've updated McAffee once already with no problems. Bad!Microsoft for making Windows incompatible with everything.

Have a good time at Comic Con. :-)
