Something is wrong - can anyone help?
My computer has been increasingly behaving weird the past 2 months.
1) Firefox keeps opening new windows at inconvenient times that I have never clicked on, never searched for and it's not a pop-up (all pop-ups are blocked)
2) Sometimes my computer won't shut down (I have a laptop). I know it's bad to unplug, so I'd leave it for the night and the next morning it would still stay "Logging off". Then I have no choice but to unplug and reboot. (This doesn't happen much anymore...)
3) Sometimes my win7 theme would flicker to a different outdated windows theme (almost looks like win98!?) and go back to win7 within 1-7 seconds or stay in the old theme until I shut down or restart.
All of this is so unpredictable. I have no idea what to expect or when. I have been suspecting a virus and have run different anti-virus and anti-spyware software (AVG, Norton, McCaffee, Panda, Ad-Aware), but they don't get much. They have removed some trojans and the logging off problem have gone away (until I try to log off tonight, probably), but they don't get much more than cookies anyway.
I've also tried the system restore, but I don't get points further back than 7 days and on trying to create a point, it didn't work. (I don't know how, I guess. I did read the tutorial, but it didn't help me with the correct words or whatever to create the point)
What's going on? Have I done something wrong? Can it be fixed? Is this some kind of crazy virus that no anti-virus software can detect? Should I take my computer to a technician?
I'd appreciate any advice!
