Where did I get the Ransom:MSIL/Revilcrypt.PAA!MTB?

Usual methods of Ransom:MSIL/Revilcrypt.PAA!MTB distribution are standard for all other ransomware examples. Those are one-day landing websites where victims are offered to download the free program, so-called bait e-mails and hacktools. Bait emails are a quite new tactic in malware spreading – you receive the email that mimics some normal notifications about shipments or bank service conditions updates. Within the e-mail, there is a corrupted MS Office file, or a web link which opens the exploit landing site.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Preventing it looks pretty easy, but still needs tons of focus. Malware can hide in various spots, and it is much better to prevent it even before it invades your PC than to depend on an anti-malware program. General cybersecurity awareness is just an essential item in the modern world, even if your interaction with a computer remains on YouTube videos. That can keep you a great deal of time and money which you would spend while seeking a solution.
