Okay so I have Norton 2011. I saw in a newspaper and youtube it's good. But once I posted it on a forum everyone way like McAfee and all that. I once used McAfee and whenever it scanned it took at least a minutes to load a page and for full scans it took almost 16 HOURS. But Norton it doesn't slow and it's just great. I used 2010 to before I upgraded and perfect to. I use Windows 7 and my mom uses Windows XP and it works great on both. When did people get these bad things about Norton?
