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

Common tactics of Ransom:Win32/StopCrypt.SO!MTB spreading are typical for all other ransomware examples. Those are one-day landing sites where victims are offered to download the free app, so-called bait e-mails and hacktools. Bait emails are a relatively new tactic in malware distribution – you get the email that mimics some routine notifications about shippings 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 page.

Malicious email spam

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

Preventing it looks fairly simple, but still requires a lot of recognition. Malware can hide in various places, and it is much better to stop it even before it invades your computer than to depend on an anti-malware program. General cybersecurity knowledge is just an important thing in the modern-day world, even if your relationship with a computer stays on YouTube videos. That can save you a great deal of money and time which you would spend while looking for a fixing guide.
