One day when I turned on my computer- after it working fine previously, although a blue screen did come up every now and again, which went after restarting- there was an anti-virus program thing which looked suspicious and fake. It had a fake windows symbol and I couldn't exit out of it so I accepted it, to see if I could get it off my screen somehow after that. But it started downloading files onto my computer or something. I still couldn't exit it so I just turned off the computer. I think it was turned off before it was complete.
Then my sister brought it to a computer guy. When I got it back, it turned on and I was able to use it. He had downloaded the free version of AVG anti-virus. It had a list of different files, and said that they had the trojan horse virus and were whitelisted. I didn't remove it because I looked it up and it said they were important files, and also I was hoping I could still use my computer, even with the anti-virus thing popping up all the time.
The next time I turned it on, a blue screen popped up saying 'STOP:c000021a'(Fatal System Error) The Windows Logon Process system process terminated unexpectedly with a status of 0xc0000034 (0x00000000 0x00000000). The system has been shut down.
I tried to put it on safe mode and going to the last known good configuration, but the screen appeared again.
I've googled it, do I need to reinstall the OS? I use a netbook and it has no disc drive.
I'm at loss as what to do. There's nothing majorly important on there so I wouldn't mind wiping it all out but I'm not sure how.
Can anyone assist me at all? Or is my computer beyond repair?
btw, i use Windows XP home edition.
