Is DCLUSR50.BPL safe?
Strong tier-1 consensus on the Induc virus family with packed unsigned dropper behaviour.
54 of 77 engines flag the file, 13 of them tier-1 agreeing on the Induc family. The sample is unsigned, packed, and contacted an external IP address, matching classic dropper/stager patterns.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
54 of 77 engines flag the file, 13 of them tier-1 agreeing on the Induc family. The sample is unsigned, packed, and contacted an external IP address, matching classic dropper/stager patterns.
Thirteen tier-1 engines converge on the Induc family, satisfying the strong-consensus rule. The file is unsigned and shows high-entropy packed code, a combination that rarely appears in legitimate software. Sandbox traces reveal direct-IP contact and mutex creation consistent with stager behaviour. No signer history, no RAG matches, and no external-intel clean signals exist to offset the detections. The combination of tier-1 consensus, packing, unsigned status, and network activity places the file firmly in the malicious category.
What We Detected
54 of 77 engines report the file malicious, with 13 tier-1 engines naming the Induc family. The PE is packed (high-entropy CODE section) and carries no digital signature. Sandbox execution recorded contact to IP 134.170.185.211 and creation of multiple CTF mutexes.
Threat Behavior
Induc is a file-infector virus that spreads by appending its code to other executables. The observed packing hides the payload until runtime, and the direct-IP connection is typical of downloaders or reporting stages. No dropped children or persistence registry keys were recorded in the available sandbox trace.
What To Do Now
Quarantine or delete the file. Scan any systems that executed it for additional infections. Keep endpoint protection enabled and avoid running unsigned executables from untrusted sources.
- Strong tier-1 family consensus on Induc
- Unsigned and packed PE
- Direct-IP network contact observed
- Long-lived malicious reputation since 2015
Remove the file and scan the host; do not execute or distribute it.

Threat context
How trojans work
A trojan disguises itself as something useful or harmless to trick you into running it. Once open, it does its real job in the background — anything from stealing data to opening a back door or downloading more malware.
Bottom line:The disguise is the whole trick, so a trustworthy-looking name or icon means nothing.

Signatures and behavior heuristics
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
PE is packed (high-entropy code or known packer) AND unsigned AND at least one engine flagged it. Packing alone is common in legit software; packing + unsigned + signal is the malware-dropper pattern.
Evidencehigh-entropy code sectionThe sample contacted an external IP address directly and no application domain was recorded. Direct-IP traffic also occurs in legitimate installers and infrastructure, so this is supporting context only and requires corroboration from host reputation and other runtime evidence.
Evidence134.170.185.211Unsigned, packed PE with sandbox-observed network activity. The packing step hides the payload until execution; the network call fetches / reports for the next stage. Classic dropper / stager behaviour.
