HELP - Virus = Blue screen of death

Hi,

I desperately need help. My computer has a virus and as a Diploma Architecture student with only weeks to go until my final hand in, I am close to having a panic attack.

I opened a file that I'd downloaded and it immediately crashed my laptop - I'd scanned the file with Microsoft Security Essentials and it had said 'no virus detected' altho this has clearly been shown to be the case. In the zip I noticed that there were 2 other files with the .exe file I clicked - one being a .info file and the other being some other system type file I can't remember the ext of.

After double clicking the file, my laptop immediately restarted. When I try loading Windows 7 normally, the laptop freezes shortly after I enter my password.

If I enter safe mode, the laptop will give me the blue screen of death after I enter my password, with the message 'IRQL_LESS_OR_NOT_EQUAL'.

Strangely, when I tried to enter 'Safe mode with Command Prompt', it just loaded up Windows in Safe mode (no command prompt) and I would get the blue screen, as described above, although after a few attempts it finally has allowed me to reach DOS command line.

I tried to run Microsoft Security Essentials from Command Line; although on my first attempt, I yet again got the blue screen after spending about 10 mins in DOS.

I tried again, and Safe Mode+Command line seems stable on this 2nd attempt; I am currently running a full system scan using Microsoft Security Essentials from Command Line - The scan has yet to complete.

I wanted advice on how I should proceed. I'm no expert at all, but from what I read, I suspect that my registry is now corrupt and will need repairing, even if the virus scan manages to locate and delete the original virus. If I am wrong here please let me know, or otherwise confirm.

Could someone please offer me some advice on what I should do next?

Apologies for the lack of specific technical info about my laptop setup. As mentioned, I am merely a layman and not sure what info I need to post. If you need further info, please advise me what it is you need and how I can go about collecting the data.

Thanks in advance,

Will

first thing i would do is get a clone of ur HDD, IF your work is so important before anything is done to start with, and also what is the error number when u bluescreen? like 0x0000**

Thanks for the help richyrichuk & Jacee.

I managed to fix it in the end. I ended up using the command 'bootrec.exe /fixMbr from command line and everything is back to normal.

I'm guessing the .exe file I clicked on messed up my boot file and this command managed to restore it back to how it should be.
