let me give a more detailed description of what happened.
2 computers in the house, both on XP. Upstairs (my moms) & downstairs (mine).
My mom uses IE even though I tell her not to and provided her with FF & Chrome.
McAfee always did a decent job of keeping the computer clean, backed up with Malwarebytes and System Mechanic Pro.
Downstairs my computer was always fine. Never a problem. Used only FF & Chrome. McAfee, Malwarebytes & SysMechPro.
Comcast decides that they don't want to give McAfee for free anymore and Norton was now their provided PC Protection package. so you are forced to switch. I install Norton on both machines. After about a week or 2, both Windows Firewall and Norton Total Care (or whatever it's called) says that "There is no Virus Protection on Your Computer". So I uninstall and re-install Norton on both machines. a few days later, same problem.
So I contact Norton about it, and they do some remote access to look at the downstairs computer (I'll just mimic whatever they do on the upstairs if necessary) and they uninstall MalWarebytes saying that it is incompatible.... uninstall and reinstall Norton again.
the next time I visit my moms house a week or 2 later, the computer isn't responding and I find out that it had blue screened.
So i reset it and it loaded up fine but now I see the "There is no Virus Protection on Your Computer" message again. I start looking at all my programs again (no one has used this computer since the last time I used it with the Norton guy), notice nothing out of the ordinary and then my computer bluescreens again. I reboot and contact Norton again dropping the blame on them for their faulty software supposedly not doing what it's supposed to do (Norton telling me there is no virus protection when Norton is the Virus protection) and they take remote control again. several blue screens later, all he did was uninstall and reinstall Norton and leave the case as "Open" since after 2 hours of nothing, I had better things to do than watch him not do anything to fix my problem that his company and their software created.
in the meantime, it's running smooth on the Win7 machine, so I decided to just install Win7 like I meant to many months ago.
