Trojan:Win32/Virtumonde.O is ransomware-type malware. It looks for the files on your disks, encrypts it, and after that asks you to pay the ransom for getting the decryption key.

Ordinary tactics of Trojan:Win32/Virtumonde.O spreading are standard for all other ransomware variants. Those are one-day landing web pages where users are offered to download and install the free software, so-called bait e-mails and hacktools. Bait emails are a quite modern tactic in malware spreading – you get the email that mimics some regular notifications about deliveries or bank service conditions changes. Within the e-mail, there is an infected 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.

Avoiding it looks pretty easy, however, still demands tons of awareness. Malware can hide in different places, and it is much better to stop it even before it goes into your PC than to trust in an anti-malware program. Essential cybersecurity knowledge is just an essential item in the modern world, even if your interaction with a PC stays on YouTube videos. That may save you a great deal of time and money which you would spend while looking for a fix guide.
