Where did I get the Ransom:Win32/StopCrypt.PBH!MTB?

Typical ways of Ransom:Win32/StopCrypt.PBH!MTB injection are usual for all other ransomware examples. Those are one-day landing sites where victims are offered to download and install the free program, so-called bait e-mails and hacktools. Bait emails are a relatively new method in malware distribution – you receive the e-mail that mimics some standard notifications about deliveries 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.

Avoiding it looks fairly simple, however, still demands tons of awareness. Malware can hide in various spots, and it is much better to prevent it even before it gets into your system than to rely on an anti-malware program. Common cybersecurity awareness is just an essential thing in the modern-day world, even if your relationship with a PC remains on YouTube videos. That may keep you a lot of money and time which you would certainly spend while looking for a fix guide.
