Ransomware has actually been a headache for the last 4 years. It is hard to realize a more harmful malware for both individual users and organizations. The algorithms utilized in Trojan:Win32/Tnega.PKF!MTB (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 currently exists, and possibly will exist. However, that virus does not do all these horrible things immediately – it may take up to a few hours to cipher all of your files. Therefore, seeing the Trojan:Win32/Tnega.PKF!MTB detection is a clear signal that you need to begin the clearing procedure.

Where did I get the Trojan:Win32/Tnega.PKF!MTB?

Typical ways of Trojan:Win32/Tnega.PKF!MTB spreading are basic for all other ransomware examples. Those are one-day landing web pages where users are offered to download the free program, so-called bait e-mails and hacktools. Bait emails are a pretty modern method in malware distribution – you get the e-mail that mimics some standard notifications about deliveries or bank service conditions changes. Inside of the e-mail, there is a malicious 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 fairly simple, but still demands a lot of awareness. Malware can hide in various places, and it is better to prevent it even before it invades your PC than to rely on an anti-malware program. Simple cybersecurity awareness is just an important thing in the modern-day world, even if your interaction with a computer remains on YouTube videos. That can keep you a great deal of time and money which you would spend while looking for a fixing guide.
