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

General methods of Ransom:Win32/StopCrypt.PBT!MTB spreading are basic for all other ransomware examples. Those are one-day landing sites where users are offered to download and install the free program, so-called bait emails and hacktools. Bait e-mails are a relatively modern tactic in malware spreading – you receive the e-mail that imitates some routine notifications about deliveries or bank service conditions updates. Inside of the email, there is a malicious MS Office file, or a web link which leads to the exploit landing page.

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

Preventing it looks pretty uncomplicated, however, still needs a lot of recognition. Malware can hide in different spots, and it is much better to prevent it even before it invades your system than to depend on an anti-malware program. Basic cybersecurity knowledge is just an important item 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 certainly spend while looking for a solution.
