Standard ways of Ransom:Win32/StopCrypt.SLV!MTB distribution are typical for all other ransomware variants. Those are one-day landing web pages where victims are offered to download and install the free app, so-called bait emails and hacktools. Bait emails are a pretty new tactic in malware spreading – you receive the e-mail that mimics some routine notifications about shipments or bank service conditions shifts. Inside of the e-mail, there is an infected MS Office file, or a link which leads to the exploit landing page.

Standard cybersecurity awareness is just an essential thing in the modern-day world, even if your interaction with a PC remains on YouTube videos.
