You are fucked unless you pay the cash.
I saw a plug on CNN about a virus where the hackers basically take over your computer, encrypt all your files and ask you to pay the money upfront or risk losing all the files. They keep increasing the amount if you delay payment. Apparently, this had happened to a businessman who needed some cruicial files and contacts in his computer for business deals. He approached the real FBI about this and they couldn't help him much to crack open the files. Like you mentioned, when the hackers take over your computer, they make you believe its the FBI or government taking over your computer because of child porn or so and scare you into making the payment.
which computer are you using now btw? take a screen shot of your hacked computer and show us.
My laptop seems to be working just fine now.
The virus was impotent if I tuned the radio off on the laptop, but the second I turned the radio on, BOOM, there was this damn page.
The link Woody provided did the trick - Malwarebytes.
It initially found 4 trojans, 2 of which were ransomware, but since I didn't activate the malware software, the virus loaded another file for 5. It was wild. Once I activated, I could delete all trojans.
I will be backing up my files more regularly.
I'm not worried about my emails and contacts because we use Google Cloud at work. (Though I fucking despise Gmail with all my passion, it is totally inferior to MS Outlook)
