Where did I get the Ransom:MSIL/LokiLocker.MK!MTB?

Usual ways of Ransom:MSIL/LokiLocker.MK!MTB distribution are usual for all other ransomware variants. Those are one-day landing web pages where users are offered to download and install the free software, so-called bait emails and hacktools.

Inside of the email, there is an infected MS Office file, or a link which leads to the exploit landing page.

Malicious email spam

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

Preventing it looks fairly simple, but still needs tons of recognition. Malware can hide in various places, and it is far better to prevent it even before it gets into your PC than to rely on an anti-malware program. Simple cybersecurity awareness is just an important item in the modern-day world, even if your relationship with a computer stays on YouTube videos. That can keep you a lot of time and money which you would certainly spend while searching for a solution.
