Heavy India accent. Says my computer has a virus, and wants me to let him "fix" it for me by giving him control of my computer online.
DON'T EVER DO THIS! NEVER!
They want control of your computer so that they can harvest personal information such as credit card numbers, bank account numbers, Social Security numbers, etc.
If you've already been taken in by these crooks, you must immediately contact your bank, Social Security Admin., and anyone else you have an account with online. Act quickly, or you will find that your bank account had been emptied, credit cards maxed out, and there will be much more damage to come. You must also change all passwords for anything you have online, or you will find much more mayhem done in your name.
