Virus has killed my PC, any advice?

[Rafferty]

I was on the internet today when all sorts of warnings came up telling me that there was a virus on my computer. The message said it was a trojan. I installed Norton 360 on my computer and tried to start a system scan but every time I tried to load Norton it was closed and another "warning" sign popped up. It kept asking me if I wanted to deny access to the virus and every time I clicked yes it took me to an internet website trying to make me buy virus software. I've looked online and have seen that it could be something called "extortion-ware"??

I left my PC for a while, and when i returned the screen was blue with the following message:

STOP: c000021a (Fatal system error)
The windows logon process system teminated unexpectedly with a status of 0xc0000034 (0x00000000 0x00000000)
The system has been shut down

I turned the computer off and tried to turn it back on again but this just keeps on happening.

Can anyone offer any advice? Anything I can do myself to fix the problem or is it a case of taking it in somewhere to be fixed? Any ideas how much a problem like this costs to fix?

Any advice would be welcomed!
Thank you

download it on a different computer, put it on a memory stick or CD, start the infected computer in safe mode with networking, install the above program, let it do an update and run a full scan, remove anything found.

When I select safe mode it just comes up with the blue screen and error message again?

Do you have original windows cd? Boot up using that and select recovery console. You might have to perform system restore or even restore the computer to it's factory settings.

If you don't have original cd is recovery console a boot up option?

You could also try a boot disc such as UBCD4WIN, or removing the hard disk and scanning it on another computer (look for disk errors and viruses). However, we are getting into the realms of "non-beginner" and blue-screening when you try to get into safe mode doesn't sound good.

No viruses, spywares, malwares, trojans can beat the power of complete reinstall.
