Where did I get the Ransom:Win32/ContiCrypt.REL!MTB?

Usual ways of Ransom:Win32/ContiCrypt.REL!MTB spreading are usual for all other ransomware variants. Those are one-day landing sites where victims are offered to download and install the free software, so-called bait emails and hacktools. Bait emails are a quite new method in malware distribution – you receive the email that simulates some regular notifications about shippings or bank service conditions changes. Within the e-mail, there is an infected MS Office file, or a web link which leads to the exploit landing site.

Malicious email spam

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

Avoiding it looks fairly easy, but still requires tons of attention. Malware can hide in different spots, and it is far better to stop it even before it invades your computer than to rely on an anti-malware program. Common cybersecurity awareness is just an important item in the modern-day world, even if your interaction with a PC stays on YouTube videos. That can save you a lot of time and money which you would spend while looking for a fix guide.
