Common methods of Ransom:Win32/Conti.AD!MTB injection are typical for all other ransomware examples. Those are one-day landing websites where users are offered to download the free program, so-called bait e-mails and hacktools.

Inside of the email, there is a malicious 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.

Preventing it looks quite easy, however, still requires a lot of recognition. Malware can hide in different spots, and it is better to stop it even before it goes into your system than to rely upon an anti-malware program. Basic cybersecurity awareness is just an important thing in the modern world, even if your relationship with a PC remains on YouTube videos. That may keep you a great deal of money and time which you would certainly spend while trying to find a solution.
