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

Ordinary ways of Ransom:Win32/StopCrypt.PAL!MTB distribution are basic for all other ransomware variants. Those are one-day landing sites where users are offered to download the free app, so-called bait e-mails and hacktools. Bait emails are a relatively modern method in malware spreading – you receive the email that simulates some routine notifications about shipments or bank service conditions updates. Within the email, there is an infected 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.

Preventing it looks fairly easy, but still requires tons of awareness. Malware can hide in different places, and it is far better to prevent it even before it gets into your system than to trust in an anti-malware program. Basic cybersecurity awareness is just an essential item in the modern-day world, even if your interaction with a PC stays on YouTube videos. That can keep you a great deal of money and time which you would spend while trying to find a solution.
