Query: DON'T EVEN THINK ABOUT THIS PRODUCT!

Downloading and installing the update to Norton 360 was the worst mistake I've made with my computer in ages. It completely obliterated by wireless connection (which is still not fixed) and interfered with my QuickBooks prgram. (Three pages of instructions from QuickBooks on how to fix it which I haven't attempted as yet! (But at least QuickBooks is addressing the issue. Norton doesn't seem to know or care that it's new program is destroying other programs upon installation.) I haven't been able to do work for 2 days now and there's not a light at the end of the tunnel yet. I spent over 4 hours with Norton chat support and nothing was resolved. Yikes. DON'T DO IT!!!
