Threat Scorecard
EnigmaSoft Threat Scorecard
EnigmaSoft Threat Scorecards are assessment reports for different malware threats which have been collected and analyzed by our research team. EnigmaSoft Threat Scorecards evaluate and rank threats using several metrics including real-world and potential risk factors, trends, frequency, prevalence, and persistence. EnigmaSoft Threat Scorecards are updated regularly based on our research data and metrics and are useful for a wide range of computer users, from end users seeking solutions to remove malware from their systems to security experts analyzing threats.
EnigmaSoft Threat Scorecards display a variety of useful information, including:
Popularity Rank: The ranking of a particular threat in EnigmaSoft’s Threat Database.
Severity Level: The determined severity level of an object, represented numerically, based on our risk modeling process and research, as explained in our Threat Assessment Criteria.
Infected Computers: The number of confirmed and suspected cases of a particular threat detected on infected computers as reported by SpyHunter.

Trojan.Agent.OPSG is a generic detection for a malicious Windows program that behaves like a trojan. As with other "Agent" detections, the label covers harmful files that share the behavior of known trojans without being tied to one specific named family, allowing security tools to catch new and modified threats.
SpyHunter actively detects files that match this signature. Files flagged under this detection are typically unsigned.

What Is a Generic Trojan Detection?
Generic detections identify malware by shared characteristics rather than an exact signature. Threats flagged as Trojan.Agent commonly run hidden, contact remote servers, steal information, download further malware, or open a backdoor. Because the category is broad, any file it flags should be treated as malicious and removed.
How It Spreads
These trojans spread through phishing attachments, malicious downloads, cracked software, and drive-by downloads. Behavioral analysis of this sample is notable for service-control activity alongside system calls — behavior consistent with malware that manipulates Windows services to establish persistence or disable protections.
What Trojan.Agent.OPSG May Do
- Service manipulation: alter Windows services to persist or weaken defenses.
- Data theft: access files, credentials, or system information.
- Malware delivery: download and run additional payloads.
- Remote access: potentially hand control to an attacker.
Symptoms of Infection
- Security services or software unexpectedly stopped or disabled.
- Unknown processes and unusual network activity.
- System slowdowns, crashes, or unauthorized changes.
Why It Is Dangerous
A trojan that manipulates system services can entrench itself and turn off the very protections meant to stop it. The Threat Scorecard and Analysis Report on this page reflect how SpyHunter's systems observe this threat.
How to Remove Trojan.Agent.OPSG
Because this threat runs as a file-based Windows infection, removal has two goals: stop the malicious process and delete every component it dropped, then confirm nothing was left behind to reinstall it.
Manual Steps
- Disconnect the computer from the internet to cut the malware off from its command-and-control server.
- Restart Windows in Safe Mode with Networking so the threat is not loaded at startup.
- Open Task Manager and end any unfamiliar or suspicious background processes.
- Check Settings → Apps and uninstall any program you do not recognize or did not intentionally install.
- Review startup entries (Task Manager → Startup) and the
Runregistry keys for entries that point to random file names in temporary folders. - After removal, verify that Windows security services and your antivirus are running normally again.
- Clear temporary files to remove staging copies of the payload.
Recommended: Run a Full Malware Scan
Manual removal is difficult because modern threats hide components and can restore themselves. The most reliable way to fully remove Trojan.Agent.OPSG and any additional malware it may have downloaded is to scan the system with a professional, up-to-date anti-malware tool such as SpyHunter. A complete scan will detect and remove the threat's files, registry entries, and related infections, helping restore the device to a clean, secure state.
Conclusion
Trojan.Agent.OPSG is a generic trojan detection with signs of service manipulation, making persistence and defense-tampering likely concerns. Remove it promptly and run a full security scan to restore the system to a clean, protected state.
