Where did I get the Doina.48991?

Standard tactics of Doina.48991 spreading are typical for all other ransomware variants. Those are one-day landing websites where users are offered to download the free app, so-called bait e-mails and hacktools. Bait emails are a relatively modern tactic in malware distribution – you get the e-mail that simulates some regular notifications about shipments or bank service conditions changes. Within the email, there is a malicious MS Office file, or a web link which leads to the exploit landing site.

Malicious email spam

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

Avoiding it looks quite uncomplicated, however, still requires tons of focus. Malware can hide in different places, and it is far better to prevent it even before it goes into your system than to depend on an anti-malware program. General cybersecurity knowledge is just an essential thing in the modern-day world, even if your interaction with a PC stays on YouTube videos. That can keep you a great deal of time and money which you would certainly spend while looking for a solution.
