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.Doina.AD 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.
Table of Contents
What Is Trojan.Doina.AD?
Trojan.Doina.AD flags files that behave in ways consistent with a Trojan-type threat. The analyzed sample is a Windows PE (packed: UPX!) with a signature status of Root Not Trusted, packed with UPX!. 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.Doina.AD Operates
Once executed, threats detected as Trojan.Doina.AD typically run quietly in the background, taking steps to remain on the system and to carry out their payload without alerting the user.
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:
ac60d5d28b4db345f7880e862176b1b95ffde37da40167cb1b067efae27fbda1 - File type: Windows PE (packed: UPX!)
- Signature status: Root Not Trusted
Symptoms of Infection
- Security software repeatedly reports Trojan.Doina.AD 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.Doina.AD 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.Doina.AD
Follow these general steps to remove the threat and undo the changes it may have made:
- Disconnect and reboot into Safe Mode. Disconnect from the internet and restart Windows in Safe Mode with Networking to stop the threat from running.
- 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.Doina.AD.
- Remove suspicious programs. In Settings > Apps (or Control Panel > Programs and Features), uninstall any unfamiliar applications installed around the time the problem began.
- 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.
- 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.Doina.AD 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.

Digital Signatures
Digital Signatures
This section lists digital signatures that are attached to samples within this family. When analyzing and verifying digital signatures, it is important to confirm that the signature’s root authority is a well-known and trustworthy entity and that the status of the signature is good. Malware is often signed with non-trustworthy “Self Signed” digital signatures (which can be easily created by a malware author with no verification). Malware may also be signed by legitimate signatures that have an invalid status, and by signatures from questionable root authorities with fake or misleading “Signer” names.| Signer | Root | Status |

Similar Families
Similar Families
This section lists other families that share similarities with this family, based on EnigmaSoft’s analysis. Many malware families are created from the same malware toolkits and use the same packing and encryption techniques but uniquely extend functionality. Similar families may also share source code, attributes, icons, subcomponents, compromised and/or invalid digital signatures, and network characteristics. Researchers leverage these similarities to rapidly and effectively triage file samples and extend malware detection rules.- Doina.AD
