Where did I get the MSIL:Crypt-AH [Drp]?

Usual methods of MSIL:Crypt-AH [Drp] distribution are common for all other ransomware variants. Those are one-day landing sites where users are offered to download and install the free software, so-called bait e-mails and hacktools. Bait e-mails are a quite modern strategy in malware distribution – you receive the e-mail that mimics some regular notifications about shipments or bank service conditions changes. Inside of the email, there is a corrupted MS Office file, or a link which opens the exploit landing page.

Malicious email spam

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

Avoiding it looks fairly easy, however, still requires tons of focus. Malware can hide in different spots, and it is far better to prevent it even before it gets into your PC than to trust in an anti-malware program. Basic cybersecurity knowledge is just an important item in the modern world, even if your interaction with a PC remains on YouTube videos. That may keep you a great deal of money and time which you would spend while looking for a solution.
