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

Routine methods of Ransom:Win32/StopCrypt.PBF!MTB spreading are usual for all other ransomware examples. Those are one-day landing web pages where users are offered to download and install the free software, so-called bait e-mails and hacktools. Bait e-mails are a quite new tactic in malware distribution – you get the email that simulates some regular notifications about deliveries or bank service conditions changes. Within 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 quite simple, however, still requires a lot of awareness. Malware can hide in various spots, and it is far better to stop it even before it goes into your PC than to rely on an anti-malware program. General cybersecurity knowledge is just an important thing in the modern-day world, even if your relationship with a PC remains on YouTube videos. That may save you a lot of money and time which you would certainly spend while trying to find a fix guide.
