Trojan:Win32/Vundo!A detection is a malware detection you can spectate in your computer. It generally shows up after the provoking activities on your PC – opening the dubious email messages, clicking the banner in the Web or setting up the program from unreliable sources. From the second it shows up, you have a short time to act until it begins its destructive action. And be sure – it is better not to wait for these destructive things.

What is Trojan:Win32/Vundo!A virus?

Trojan:Win32/Vundo!A is ransomware-type malware. It looks for the files on your computer, encrypts it, and then asks you to pay the ransom for getting the decryption key. Besides making your files locked, this malware also does a lot of harm to your system. It changes the networking settings in order to prevent you from checking out the removal guides or downloading the antivirus. Sometimes, Trojan:Win32/Vundo!A can even block the launching of anti-malware programs.

Trojan:Win32/Vundo!A Summary

Summarizingly, Trojan:Win32/Vundo!A ransomware actions in the infected system are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • Sample contains Overlay data;
  • Authenticode signature is invalid;
  • Encrypting the documents located 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 security tools

Ransomware has actually been a major problem for the last 4 years. It is difficult to picture a more damaging virus for both individual users and companies. The algorithms used in Trojan:Win32/Vundo!A (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have a lot more time than our galaxy actually exists, and possibly will exist. However, that malware does not do all these terrible things instantly – it may take up to a few hours to cipher all of your documents. Thus, seeing the Trojan:Win32/Vundo!A detection is a clear signal that you must start the elimination procedure.

Where did I get the Trojan:Win32/Vundo!A?

General methods of Trojan:Win32/Vundo!A injection are typical for all other ransomware examples. Those are one-day landing web pages where users are offered to download and install the free program, so-called bait e-mails and hacktools. Bait e-mails are a quite modern method in malware spreading – you receive the e-mail that imitates some normal notifications about deliveries or bank service conditions updates. Within the e-mail, there is an infected MS Office file, or a web link which leads to the exploit landing page.

Malicious email spam

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

Avoiding it looks fairly easy, however, still requires tons of attention. Malware can hide in various spots, and it is better to prevent it even before it invades your system than to rely on an anti-malware program. Basic cybersecurity knowledge is just an important item in the modern-day world, even if your relationship with a PC stays on YouTube videos. That may keep you a lot of money and time which you would spend while trying to find a fixing guide.
