Verdict Safe
Is DRTCP. exe safe? Yes, no threats found.
Only Zillya flagged this widely submitted executable, while all major antivirus engines remained silent and evidence from the test run showed no corroborating high-risk activity.

Why we think so
3 points against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
Only 1 of the 72 antivirus engines that checked it flagged the executable, using an adware label that no other engine corroborated; all 18 reporting major antivirus engines were silent. Its history spans 400 submission sources since it was first seen on Feb 20, 2007, and the sandbox summary found no high-risk techniques, injected processes, or malicious dropped files.
Zillya alone reported an adware label, while none of the 18 reporting major antivirus engines flagged the file. The executable has been submitted 504 times by 400 sources and was first seen on Feb 20, 2007, providing a substantial benign anchor. The combined sandbox summary recorded only techniques common in legitimate software, with no high-risk techniques or named injection targets. No malicious child was identified, and the executable does not show high-entropy code or recognized packing. The remaining uncertainty comes from the absent signature, unavailable static examination, and lack of a complete host-reputation check, but these do not corroborate the isolated detection.
What We Detected
Only 1 of the 72 antivirus engines that checked it flagged the executable. Zillya applied the label Adware.DLBoost.Win32.22, while all 18 reporting major antivirus engines remained silent and no second engine supported that label.
Threat Behavior
The combined sandbox summary recorded techniques common in legitimate Windows software but no high-risk techniques, named injection targets, persistence indicators, or malicious dropped files. The executable also lacked high-entropy code and recognized packing. Background network contacts were excluded from the sample's activity; no complete reputation result is available for all remaining observed contacts.
What To Do Now
The broad submission history and lack of corroborating detections make the isolated adware label likely to be a false positive. Obtain the executable from its intended trusted source and keep security software enabled, especially because the file has no verifiable publisher signature.
Where this verdict could be wrong3 caveats
- Zillya labels the executable Adware.DLBoost.Win32.22, although no other engine corroborates that unwanted program label.
- The executable is unsigned, so its publisher cannot be authenticated.
- Our static analysis was not available, and no complete reputation result is available for all observed contacts.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Only 1 of the 72 antivirus engines that checked it flagged the file, and none of the 18 reporting major antivirus engines did.
- The file has 504 submissions from 400 sources and was first seen on Feb 20, 2007.
- The sandbox summary showed no high-risk techniques or named process-injection targets.
- No malicious dropped files were identified.
- The executable shows neither high-entropy code nor recognized packing.
- Zillya labels the executable as adware, but no other engine corroborates that assessment.
- The executable has no verifiable publisher signature.
- Our proprietary static examination was unavailable, and the observed contacts did not receive a complete reputation check.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
How widely this file has been seen
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.
