HP Pavillion zv6000 boot problem

[Omoe]

Help! My HP Pavillion zv6000 laptop, with Windows XP Service Pack 3, has recently encountered some bootup problems. I think this is because I downloaded a virus of some kind (dfx9keygen.exe) and ran it. Stupidly.

So now, whenever I start up my computer, it goes to the HP screen, but right afterwards, it gets about two frames into the windows xp boot screen before I get a flicker of the bsod screen, and it directs me right back to startup options.

None of these options work, not even the safe modes.

I hear that I should probably use my recovery disk, but truthfully, I don't understand how to go about doing it.

Do I need a floppy?

If there's any simple solution to virus induced boot error, please help direct me towards it!

Thanks Johny, but I've tried multiple times to use the recovery disk. I've used chkdsk and a host of other commands in the recovery console, and I've read up on what bsod does and what causes it.

I've even repair installed the OS again (Though I should note that I only used an SP2 version of Windows XP Professional, the SP3 disk hanged when finding a human interface file).

Still nothing, I'm still getting bsod, and am still being redirected to the hp screen every time. My last resort is simply to format everything, but I'd really like to keep it as a last resort...Is this virus really unconquerable?

Does anyone recognize the kind of bug this is? I think I (stupidly) got it from here, www.keygen.ms/crack/22736/.Never going to fall for this again.

AVG on the computer I'm using now is detecting it as a bad site, but McAfee Antivirus on my busted computer didn't....

All help and expertise is appreciated!
