Replying to I NEED COMPUTER HELP RIGHT NOW PLEASE FOR THE LOVE OF ALL THAT IS HOLY

Please Help. I will be eternally greatful.

I was downloading a keygen for Magic Bullet Looks on my dad's computer, which is the computer I edit on, and when I opened it the computer shut down immediately.

I started it back up, and ran through the automatic repair, assuming that the computer would delete the virus keygen on its own. It didn't work, and the computer is saying that it cannot fix the problem automatically.

I tried a system restore to before i downloaded it, but the system restore does not delete files on its own, and therefore did not delete the virus.

My last option is to open a command prompt.

Is is possible to delete the file with the command prompt, or even possibly delete all downloaded files after a certain time this morning?

If so can somebody with command prompt knowledge please tell me what to do?
