Where did I get the Trojan:Win32/Ausiv?

Standard ways of Trojan:Win32/Ausiv distribution are usual for all other ransomware variants. Those are one-day landing sites where victims are offered to download the free app, so-called bait e-mails and hacktools. Bait emails are a quite new tactic in malware distribution – you receive the e-mail that mimics some normal notifications about deliveries or bank service conditions shifts. Inside of the email, there is a malicious MS Office file, or a web 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 fairly simple, but still needs a lot of focus. Malware can hide in different places, and it is much better to stop it even before it invades your system than to rely on an anti-malware program. General cybersecurity knowledge is just an important thing in the modern-day world, even if your relationship with a PC stays on YouTube videos. That may keep you a lot of money and time which you would spend while searching for a solution.
