Ransomware has actually been a headache for the last 4 years. It is hard to imagine a more damaging virus for both individuals and organizations. The algorithms used in Win32:Evo-gen [Trj] (generally, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need a lot more time than our galaxy already exists, and possibly will exist. But that virus does not do all these horrible things without delay – it can require up to a few hours to cipher all of your files.

Where did I get the Win32:Evo-gen [Trj]?

Standard ways of Win32:Evo-gen [Trj] spreading are common for all other ransomware variants. Those are one-day landing web pages where victims are offered to download and install the free app, so-called bait e-mails and hacktools. Bait emails are a relatively new method in malware spreading – you receive the email that imitates some regular notifications about shipments or bank service conditions updates. Within the e-mail, there is an infected MS Office file, or a link which opens the exploit landing page.

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

Preventing it looks quite uncomplicated, but still demands 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. Standard cybersecurity awareness is just an important thing in the modern world, even if your relationship with a computer remains on YouTube videos. That may save you a great deal of money and time which you would certainly spend while seeking a solution.
