Win32/Agent.ACUG detection is a virus detection you can spectate in your computer. It generally shows up after the preliminary actions on your computer – opening the suspicious email messages, clicking the banner in the Web or installing the program from dubious resources. From the moment it appears, you have a short time to do something about it before it starts its malicious activity. And be sure – it is better not to wait for these harmful actions.

What is Win32/Agent.ACUG virus?

Win32/Agent.ACUG is ransomware-type malware. It searches for the documents on your disks, encrypts it, and after that asks you to pay the ransom for getting the decryption key. Besides making your files locked, this malware also does a lot of damage to your system. It modifies the networking settings in order to prevent you from reading the removal manuals or downloading the anti-malware program. In some cases, Win32/Agent.ACUG can also block the launching of anti-malware programs.

Win32/Agent.ACUG Summary

Summarizingly, Win32/Agent.ACUG malware actions in the infected PC are next:

  • At least one process apparently crashed during execution;
  • Sample contains Overlay data;
  • Authenticode signature is invalid;
  • Ciphering the documents located on the target’s drives — so the victim cannot check these documents;
  • Blocking the launching of .exe files of anti-virus apps
  • Blocking the launching of installation files of anti-malware apps

Ransomware has been a major problem for the last 4 years. It is challenging to picture a more hazardous virus for both individuals and organizations. The algorithms used in Win32/Agent.ACUG (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need more time than our galaxy currently exists, and possibly will exist. But that virus does not do all these bad things without delay – it may require up to a few hours to cipher all of your files. Therefore, seeing the Win32/Agent.ACUG detection is a clear signal that you must begin the clearing process.

Where did I get the Win32/Agent.ACUG?

Standard ways of Win32/Agent.ACUG injection are basic for all other ransomware examples. Those are one-day landing websites where users are offered to download and install the free app, so-called bait e-mails and hacktools. Bait emails are a relatively new tactic in malware spreading – you receive the e-mail that imitates some standard notifications about shipments or bank service conditions shifts. Within the e-mail, there is a corrupted 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 quite uncomplicated, but still requires a lot of focus. Malware can hide in various spots, and it is far better to stop it even before it gets into your computer than to depend on an anti-malware program. Essential cybersecurity awareness is just an essential item in the modern world, even if your relationship with a PC stays on YouTube videos. That may save you a great deal of time and money which you would spend while trying to find a solution.
