Is dbtrial_setup.exe safe?
Unsigned installer with only one tier-1 PUP flag and common-old prevalence.
Three engines flagged the file as PUP or unwanted, but only one tier-1 engine and no sandbox malice. The file is a common installer pattern with mostly clean similar-hash history.

Before installing
Install it only when it came from the developer's official site or an official app store.
If you already installed it
Keep normal device protection enabled and stop if the file behaves unexpectedly.
Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Three engines flagged the file as PUP or unwanted, but only one tier-1 engine and no sandbox malice. The file is a common installer pattern with mostly clean similar-hash history.
The sample shows three malicious detections out of 75 engines, with only DrWeb at tier-1. No sandbox verdict, no malicious children, and no external-intel hits. Prevalence is common-old and the imphash matches two prior safe verdicts. The unsigned status and direct-IP contacts are noted but outweighed by the low-tier signals and installer context.
What We Detected
Three engines reported the file: DrWeb (tier-1) labeled it Program.Unwanted.5065, Malwarebytes (tier-2) labeled it PUP.Optional.BundleInstaller, and VBA32 (low-trust) labeled it TScope.Trojan.Delf. No tier-1 family consensus exists.
Threat Behavior
The installer wrote multiple temporary files and created mutexes typical of Inno Setup. Sandbox analysis recorded 20 ambient techniques and one offensive technique (T1134) but returned no malicious verdict. No domains were contacted and no dropped child was flagged malicious.
What To Do Now
Keep endpoint protection enabled. If the file is from the legitimate IObit Driver Booster distribution channel, the PUP labels are expected. Verify the download source before execution.
Where this verdict could be wrong1 caveat
- Direct-IP contact to 14 addresses with no domain recorded (MalwareTips.Synth.DirectIpC2) — could be benign installer traffic but coverage is incomplete.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Common-old prevalence (734 submitters)
- No malicious sandbox verdict
- No malicious dropped children
- Two of three similar imphash files previously rated safe
- Unsigned executable
- Direct-IP network traffic without domain names
The file can be executed if obtained from the official IObit site; otherwise treat as untrusted software.

Detection sources at a glance
The available sources did not agree on a named threat category.
MalwareBazaar, YARAify, and CIRCL hashlookup completed and returned no entries for this hash.
Signatures and behavior heuristics
Behavioral heuristics matched patterns associated with malware. Corroborating evidence determines how much weight they carry.
The 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.

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.
