Ransomware has actually been a headache for the last 4 years. It is difficult to imagine a more dangerous malware for both individual users and companies. The algorithms used in VHO:Trojan-Downloader.Win32.Deyma.cyv (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have more time than our galaxy currently exists, and possibly will exist. However, that malware does not do all these unpleasant things instantly – it can require up to a few hours to cipher all of your documents. Hence, seeing the VHO:Trojan-Downloader.Win32.Deyma.cyv detection is a clear signal that you should begin the removal procedure.

Where did I get the VHO:Trojan-Downloader.Win32.Deyma.cyv?

Common ways of VHO:Trojan-Downloader.Win32.Deyma.cyv spreading are usual for all other ransomware variants. Those are one-day landing sites where victims are offered to download and install the free program, so-called bait emails and hacktools. Bait e-mails are a relatively new method in malware distribution – you receive the email that mimics some normal notifications about shippings or bank service conditions changes. Within the e-mail, there is a corrupted 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 a lot of focus. Malware can hide in various spots, and it is better to prevent it even before it goes into your system than to rely upon an anti-malware program. Simple cybersecurity knowledge is just an important item in the modern world, even if your relationship with a PC stays on YouTube videos. That may keep you a great deal of time and money which you would spend while looking for a solution.
