Yes this is bogus. It is called ransomware because it is a Trojan that demands money to remove it. There are many variations of this, such as the MoneyPak scam claiming to be law enforcement and demanding you send money via MoneyPak. None of these actually fix your computer of course, but are thieves trying to steal money.
Try malwarebytes to remove it, or Google a description of the Trojan and you ought be be able to identify it and find removal instructions.
Be very cautious because many anti-Trojan programs are Trojans themselves, filled with adware and malware.
Never call the numbers provided by the Trojan, they are con-artists.
PS: I see you called the number and they want $180. They won't fix your computer anyway- it's a con-artist. Another scam is to ask for remote access to your computer, which they will use to find financial information. DO NOT CALL the number they provide!!!!
Call a tech. It's most likely Ransom Ware. If not paid, your computer could lock up entirely, encrypted so that you will be forced to pay for the key. Get a tech to remove it ASAP!
No, don't block the site, get the payload removed
