Common methods of Ransom:Win32/Filecoder.GF!MTB spreading are usual for all other ransomware variants. Those are one-day landing sites where users are offered to download the free app, so-called bait emails and hacktools. Bait emails are a pretty new tactic in malware distribution – you get the email that imitates some normal notifications about shipments or bank service conditions changes. Within the e-mail, 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.

Preventing it looks quite uncomplicated, but still requires tons of focus. Malware can hide in various places, and it is far better to stop it even before it goes into your PC than to trust in an anti-malware program. Essential cybersecurity knowledge is just an important item in the modern world, even if your relationship with a PC remains on YouTube videos. That may keep you a lot of money and time which you would certainly spend while seeking a solution.
