It generally shows up after the preliminary procedures on your PC – opening the untrustworthy email messages, clicking the advertisement in the Web or setting up the program from untrustworthy sources.

What is Trojan-Ransom.Win32.PolyRansom.byg virus?

Trojan-Ransom.Win32.PolyRansom.byg is ransomware-type malware. It searches for the files on your disk, ciphers it, and then asks you to pay the ransom for receiving the decryption key. Besides making your documents inaccessible, this malware also does a lot of harm to your system. It modifies the networking settings in order to prevent you from checking out the removal manuals or downloading the anti-malware program. In some cases, Trojan-Ransom.Win32.PolyRansom.byg can additionally stop the setup of anti-malware programs.

Trojan-Ransom.Win32.PolyRansom.byg Summary

In summary, Trojan-Ransom.Win32.PolyRansom.byg ransomware activities in the infected PC are next:

  • CAPE extracted potentially suspicious content;
  • Authenticode signature is invalid;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Encrypting the files kept on the victim’s disk drives — so the victim cannot open these files;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-malware programs

Ransomware has actually been a major problem for the last 4 years. It is difficult to picture a more dangerous virus for both individual users and companies. The algorithms utilized in Trojan-Ransom.Win32.PolyRansom.byg (generally, 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. But that malware does not do all these bad things immediately – it may take up to a few hours to cipher all of your documents. Therefore, seeing the Trojan-Ransom.Win32.PolyRansom.byg detection is a clear signal that you must start the removal procedure.

Where did I get the Trojan-Ransom.Win32.PolyRansom.byg?

Usual tactics of Trojan-Ransom.Win32.PolyRansom.byg spreading are usual for all other ransomware variants. Those are one-day landing web pages where victims are offered to download the free app, so-called bait emails and hacktools. Bait e-mails are a pretty new strategy in malware distribution – you get the e-mail that imitates some routine notifications about shipments or bank service conditions changes. Within the email, there is a corrupted 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.

Preventing it looks quite uncomplicated, however, still demands tons of recognition. Malware can hide in different spots, and it is far better to stop it even before it gets into your PC 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 stays on YouTube videos. That can save you a great deal of money and time which you would certainly spend while trying to find a solution.
