Where did I get the Trojan:MSIL/FormBook.PRY!MTB?

Common methods of Trojan:MSIL/FormBook.PRY!MTB injection are common for all other ransomware examples. Those are one-day landing web pages where victims are offered to download the free software, so-called bait e-mails and hacktools. Bait e-mails are a pretty modern tactic in malware distribution – you get the email that imitates some regular notifications about deliveries or bank service conditions updates. Inside of the e-mail, there is an infected MS Office file, or a web link which leads to the exploit landing page.

Malicious email spam

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

Avoiding it looks pretty uncomplicated, but still needs tons of focus. Malware can hide in different spots, and it is much better to prevent it even before it goes into your computer than to trust in an anti-malware program. Simple cybersecurity knowledge is just an important thing in the modern world, even if your relationship with a computer remains on YouTube videos. That may save you a great deal of time and money which you would certainly spend while trying to find a solution.
