what does this MEAN?! please help, really urgent!?

[bella :D]

i was on facebook when my computer randomly shut down.. i turned it back on and there was this message about my computer being locked and basically that if i didn't pay 200 hundred dollars, i'd basically go to jail and have my computer taken away by the government...? it said somehting about illegally downloaded audio files had been found on my computer, but i always use itunes or freegal music (through my local library) to buy my music and my user on my family's shared computer has a password, plus there's no other children in my household and my parents never buy new music.

i was on facebook and i'd gotten this notification that a friend (one i wasn't close with) had sent me a free full-length video on some app...? i never clicked on it, so i dont know.

what should i do? it sounds serious but i havent done anything wrong. help please?

sounds like a virus maybe. have you done a virus scan?

It's probably just some malware on your computer. Don't worry, you won't end up in jail. Just install some anti-malware apps and hope it's updated enough to be able to recognize and clean your problem. Try AVG or Avira.

Get malwarebytes anti malware and scan the computer

YOUTUBE Has become a haven for Viruses.
Unmonitored links that UP-loaders have provided are infected with AD-ware , SPY-Ware, Trojans & as you now know Ransom-Ware.

This one is called Ransom-ware.
It's just like SPY-ware, Ad-ware , etc....
Except this is a bunch of scumbags who prowl the internet & leave links on pages. Someone in your own neighborhood who may have got in your wireless network could even be responsible.
Just DO THIS......
ReBoot the computer & then hold F8
Starting the computer in SAFE MODE.WITH NETWORKING.
Download Malwarebytes install & run it.
Then reboot & run it again.

NOTE:
Sometimes these things get into the boot files & the Safe-Mode method will not work , so you may need the Windows 7 DVD.
If you don't have the 7 DVD, then Download & burn to disk " Hirens Boot CD ".
For either DISK method you need to set the Disk drive as your boot device.
