Where did I get the Ransom:Win32/Reveton.B?

Typical ways of Ransom:Win32/Reveton.B spreading are standard for all other ransomware examples. Those are one-day landing websites where victims are offered to download and install the free program, so-called bait e-mails and hacktools. Bait emails are a pretty new method in malware distribution – you receive the email that simulates some routine notifications about shippings or bank service conditions updates. Within the email, there is a corrupted MS Office file, or a web link which leads to the exploit landing page.

Malicious email spam

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

Preventing it looks pretty easy, but still needs tons of awareness.

Essential cybersecurity awareness is just an essential item in the modern world, even if your relationship with a PC stays on YouTube videos. That can save you a great deal of time and money which you would certainly spend while seeking a fix guide.
