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

Standard tactics of Ransom:Win32/StopCrypt.PAG!MTB spreading are typical for all other ransomware examples. Those are one-day landing web pages where victims are offered to download and install the free program, so-called bait e-mails and hacktools. Bait emails are a pretty new method in malware distribution – you receive the e-mail that simulates some normal notifications about shippings or bank service conditions changes. Within the email, there is a malicious 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 easy, however, still requires a lot of focus. Malware can hide in different places, and it is far better to prevent it even before it invades your computer than to rely on an anti-malware program. Essential cybersecurity knowledge is just an important thing in the modern world, even if your relationship with a computer stays on YouTube videos. That can keep you a lot of money and time which you would spend while seeking a solution.
