WinGo/TrojanDropper.Agent.AD detection is a virus detection you can spectate in your system. It frequently appears after the preliminary actions on your PC – opening the dubious e-mail messages, clicking the advertisement in the Internet or installing the program from dubious 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 much better not to wait for these destructive things.

What is WinGo/TrojanDropper.Agent.AD virus?

WinGo/TrojanDropper.Agent.AD is ransomware-type malware. It looks for the files on your disks, encrypts it, and after that asks you to pay the ransom for receiving the decryption key. Besides making your files locked, this malware also does a lot of harm to your system. It modifies the networking setups in order to prevent you from checking out the elimination tutorials or downloading the anti-malware program. In rare cases, WinGo/TrojanDropper.Agent.AD can also prevent the launching of anti-malware programs.

WinGo/TrojanDropper.Agent.AD Summary

Summarizingly, WinGo/TrojanDropper.Agent.AD virus actions in the infected PC are next:

  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Dynamic (imported) function loading detected;
  • The binary contains an unknown PE section name indicative of packing;
  • Authenticode signature is invalid;
  • Encrypting the documents located on the target’s disk drives — so the victim cannot check these documents;
  • Blocking the launching of .exe files of anti-malware apps
  • Blocking the launching of installation files of security tools

Ransomware has been a major problem for the last 4 years. It is hard to imagine a more harmful virus for both individuals and businesses. The algorithms used in WinGo/TrojanDropper.Agent.AD (usually, 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 actually exists, and possibly will exist. But that virus does not do all these bad things instantly – it can take up to a few hours to cipher all of your files. Thus, seeing the WinGo/TrojanDropper.Agent.AD detection is a clear signal that you have to begin the elimination process.

Where did I get the WinGo/TrojanDropper.Agent.AD?

Standard tactics of WinGo/TrojanDropper.Agent.AD distribution are basic for all other ransomware examples. Those are one-day landing websites where victims are offered to download and install the free app, so-called bait e-mails and hacktools. Bait e-mails are a pretty new strategy in malware spreading – you receive the email that simulates some routine notifications about deliveries or bank service conditions shifts. Within the e-mail, there is an infected MS Office file, or a 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 quite simple, however, still needs tons of focus. Malware can hide in different places, and it is much better to prevent it even before it goes into your computer than to rely upon an anti-malware program. Common cybersecurity awareness is just an important item in the modern world, even if your interaction with a computer stays on YouTube videos. That can save you a lot of money and time which you would certainly spend while trying to find a solution.
