Computer Boots, but once in natta.

[runamuck]

I wish I had any idea what is going on, but i don't. Computer boot seemed to get slower and slower over the last 4 months or so. I tried to open a .asf file the night before last and my VPN viewer tried to update. When it did it downloaded mallware. I uninstalled the whole deal. Then I took it back to a restore point to about 3 weekds ago. The popups kept coming up. I disallowed them, but they came back.

At some point or other, I shut it down and when I booted it back up it will go all the way into windows but it's like the system programs aren't fully opening or something. The only thing I can get to come up at this point is my Norton Virus manager. If I click on the control panel, it freezes instantly. IE won't even initiate, I try to go to task manager and everything but the background pic will go away and it will freeze that way. I cannot shut down through the start button - same thing happens.

Nothing works but Norton.

I bring it up in Safe Mode and it comes right up. Does anyone know what I did to this thing?
Windows 7 pro - toshiba - 32 bit IE8

UPDATE:
I tried going into windows using my daughters login and everything is working fine, as slow as usual, but everything is coming up. So what the heck?
