Ransomware has been a headache for the last 4 years. It is challenging to imagine a more harmful virus for both individuals and companies. The algorithms utilized in Win32:GenMalicious-NTB [Trj] (generally, RHA-1028 or AES-256) are not hackable – with minor exclusions.

Therefore, seeing the Win32:GenMalicious-NTB [Trj] detection is a clear signal that you need to start the elimination process.

Where did I get the Win32:GenMalicious-NTB [Trj]?

Common methods of Win32:GenMalicious-NTB [Trj] injection are usual for all other ransomware variants. Those are one-day landing web pages where victims are offered to download the free program, so-called bait e-mails and hacktools. Bait e-mails are a relatively new method in malware spreading – 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 link which opens the exploit landing page.

Malicious email spam

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

Preventing it looks fairly easy, but still needs tons of awareness. Malware can hide in various places, and it is much better to prevent it even before it goes into your system than to rely on an anti-malware program. Standard cybersecurity awareness is just an essential thing in the modern world, even if your relationship with a PC remains on YouTube videos. That can keep you a lot of money and time which you would certainly spend while searching for a fix guide.
