Searched my laptop for viruses and only came up with 1 Trojan, which I'm getting rid of. Computer is still lagging like never before, though. After that storm last night, my computer takes no less than 15 minutes to restart (with all functions intact--It usually takes 2 minutes, but then another 13 waiting for the computer to recognize half the programs and files on it). It also can't hold a steady Internet connection--I can't get it to stay for longer than a few minutes. But it seems to work for everyone else in the house.

Oh yeah, and running Firefox alone causes the computer to start overheating and takes up no less than 40% of the CPU.

Not a clue what's wrong with it. Any ideas or suggestions what I should do? The last thing I downloaded was my anti-virus (McAfee), from a USB stick of my dad's. Not two days after, my computer begins to fall apart at the seams.

Also, I think I'm falling apart at the seams. I'm constantly fatigued and ready to drop over dead all the time even though I'm sleeping about the same amount as usual, and I'm not sleeping badly. I'm still in the state of constant nausea and mild dizziness.
