Trojan.Agent.MPG is the SpyHunter detection name for a Trojan-type threat. This report summarizes what security researchers observe from samples that match this detection and explains how to remove the threat from an affected device.

Detections in this class are assigned by signature and behavioral analysis rather than to a single, named malware family, so the exact payload can vary between samples. The behavior described below is drawn from automated analysis of a representative sample and should be treated as indicative rather than exhaustive.

What Is Trojan.Agent.MPG?

Trojan.Agent.MPG flags files that behave in ways consistent with a Trojan-type threat. The analyzed sample is a Windows PE executable with a signature status of No Signature. Because the detection is signature-based, files caught by it may be delivered through a range of channels — bundled installers, cracked or pirated software, malicious email attachments, or drive-by downloads from untrustworthy sites.

How Trojan.Agent.MPG Operates

In the analyzed run, the sample created or modified files such as:

  • c:program fileswindowspowershellmpcmdrun.exe
  • devicenamedpipedav rpc service
  • devicenamedpipepshost.134269684666516436.3632.defaultappdomain.powershell
  • devicenamedpipewkssvc
  • c:usersuserappdatalocaltemp__psscriptpolicytest_22dgmu3p.ghr.ps1

It also set Windows Registry values, including:

  • HKLMsystemcontrolset001servicesbamstateusersettingss-1-5-21-3119368278-1123331430-659265220-1001::deviceharddiskvolume2windowssystem32conhost.exe

These file and registry indicators come from one sandbox run; exact names and locations differ from sample to sample.

Malware Analysis

The values below are for a single representative sample. A signature-based detection matches many distinct files, so treat these as one example rather than the only indicator of compromise:

  • SHA-256: ac0ef032165f08ebf92702b3c401b801e944638c81e979e29473897c69c35dff
  • File type: Windows PE executable
  • Signature status: No Signature

Symptoms of Infection

  • Security software repeatedly reports Trojan.Agent.MPG on the device.
  • The system runs slower than usual, or unfamiliar processes appear in Task Manager.
  • Unexpected network activity, new files, or changed settings that you did not authorize.

Why Trojan.Agent.MPG Is a Risk

Any file that triggers this detection should be treated as untrusted. Threats in this category can be used to download further malware, steal information, or give an attacker a foothold on the system. Even if a single sample appears low-impact, leaving it in place exposes the device to the additional payloads it may fetch.

How to Remove Trojan.Agent.MPG

Follow these general steps to remove the threat and undo the changes it may have made:

  1. Disconnect and reboot into Safe Mode. Disconnect from the internet and restart Windows in Safe Mode with Networking to stop the threat from running.
  2. Run a full anti-malware scan. Use a reputable, up-to-date security tool such as SpyHunter to scan the entire system and quarantine everything detected as Trojan.Agent.MPG.
  3. Remove suspicious programs. In Settings > Apps (or Control Panel > Programs and Features), uninstall any unfamiliar applications installed around the time the problem began.
  4. Reset affected browsers. In Chrome, Firefox, and Edge, remove unknown extensions and reset settings to clear any changes made to your homepage or search provider.
  5. Reboot and re-scan. Restart normally and run a second full scan to confirm the system is clean.

Running a full system scan with an anti-malware tool such as SpyHunter is the most reliable way to detect every component associated with this threat and remove it completely.

Conclusion

Trojan.Agent.MPG is a Trojan-type threat that should be removed promptly. Because it is detected by signature and behavior, the safest approach is a full anti-malware scan followed by the cleanup steps above, plus cautious downloading habits to avoid re-infection.
