Standard tactics of TrojanDropper:Win32/Agent.UM spreading are typical for all other ransomware examples. Those are one-day landing websites where victims are offered to download the free app, so-called bait emails and hacktools.

Inside of the e-mail, there is a corrupted MS Office file, or a link which leads to the exploit landing site.

Malicious email spam

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

Preventing it looks quite easy, but still demands tons of focus. Malware can hide in various spots, and it is better to stop it even before it invades your system than to rely upon an anti-malware program. Basic cybersecurity knowledge is just an important thing in the modern-day world, even if your relationship with a computer remains on YouTube videos. That may keep you a lot of time and money which you would spend while trying to find a solution.
