Where did I get the Trojan:Win32/Malgent.B?

Routine tactics of Trojan:Win32/Malgent.B spreading are typical for all other ransomware examples. Those are one-day landing websites where victims are offered to download the free software, so-called bait e-mails and hacktools. Bait emails are a quite new strategy in malware distribution – you receive the email that simulates some regular notifications about shipments or bank service conditions modifications. Within the e-mail, there is a corrupted MS Office file, or a link which opens the exploit landing site.

Malicious email spam

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

Malware can hide in different spots, and it is better to stop it even before it gets into your PC than to trust in an anti-malware program. General cybersecurity knowledge is just an essential item in the modern world, even if your relationship with a computer stays on YouTube videos. That can keep you a great deal of money and time which you would certainly spend while seeking a solution.
