Where did I get the Sf:Crypt-BT [Trj]?
Standard methods of Sf:Crypt-BT [Trj] spreading are typical for all other ransomware examples. Those are one-day landing sites where users are offered to download and install the free program, so-called bait e-mails and hacktools. Bait e-mails are a pretty modern tactic in malware spreading – you get the email that imitates some regular notifications about shipments or bank service conditions updates. Inside of the email, there is a corrupted MS Office file, or a link which opens the exploit landing site.

Malicious email message. This one tricks you to open the phishing website.
Avoiding it looks fairly simple, however, still needs tons of attention. Malware can hide in different places, and it is much better to stop it even before it invades your system than to depend on an anti-malware program. General cybersecurity knowledge is just an important thing in the modern world, even if your relationship with a computer 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.
