It doesn't matter where you get bitcoins, they are not limited to locales. As long as you have them, you can pay the ransom to the attackers.
Be very careful though.
There are scammers and thieves that take advantage of your sense of urgency and your lack of experience. There are many places on the internet that will promise that you'll get bitcoins in exchange for payment, and then after you send payment they'll just disappear without ever ending you any bitcoins.
Make sure that wherever you are getting the bitcoins from is a reliable source.
Again, thanks to all. You guys have been very helpful.
Good to know that they can be bought anywhere and be spent.
Danny has some of the best advice make sure not to accept help through teamviewer or other from a low trust source. People will pry on your situation.
My advice is try to see if you can get into safemode. Assuming you can get into safe mode then look at processes running, anything looks funny stop the process.
After try malwarebytes and your favorite anti-virus. Hopefully in safe mode you can get all of it gone on the virus. Also think of updating virus protection or switching if it allowed you to get this virus.
