Is VdiInst.exe safe?

Verdict
Suspicious

All 76 engines were silent and the signature verifies, but seven YARA matches, T1134, and unchecked direct-IP traffic justify caution.

The executable has a valid Tencent signature, and none of 76 antivirus engines detected it, including all 17 reporting tier-1 engines. However, seven community YARA rules matched, one sandbox observed T1134 and direct-IP traffic, and no complete reputation check is available for those IP addresses.

Do not run it until verified

Verify that the executable came directly from an official Tencent channel and confirm its certificate before running it. Keep endpoint protection enabled and quarantine it if its origin cannot be established.

01

Before running

Do not run it until the source and publisher can be verified independently.

02

If you already ran it

Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the developer's official site or an official app store.

Analyst conclusion

The executable has a valid Tencent signature, and none of 76 antivirus engines detected it, including all 17 reporting tier-1 engines. However, seven community YARA rules matched, one sandbox observed T1134 and direct-IP traffic, and no complete reputation check is available for those IP addresses.

Where this verdict could be wrong4 caveats
  • Seven YARAify rules matched, which is substantial researcher-rule convergence even though the exposed rules do not identify a specific malware family.
  • The sample contacted three external IP addresses directly, and contactedHosts=null means their reputation was not completely checked.
  • communityComments[0] associates the hash with Black Basta, HijackLoader, and Luca Stealer, but the annotation has zero votes and no independent detection consensus.
  • T1134 was observed in the completed sandbox run and may indicate access-token manipulation, although the sandbox did not issue a malicious verdict.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Recommended action

Verify that the executable came directly from an official Tencent channel and confirm its certificate before running it. Keep endpoint protection enabled and quarantine it if its origin cannot be established.

What this file does

Observed actions and their security significance

  • High concern: Used an input-capture technique that can record credentials or keystrokes.

  • Moderate concern: Runs hidden system commands (script or shell).

  • Moderate concern: Scans through your files and folders.

  • Moderate concern: Checked the environment for virtualisation or analysis tools.

  • Moderate concern: Checks which security software you have installed.

  • Note: Listed running processes; both legitimate software and malware may do this.

  • Note: Collects details about your system.

These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file never ran on your device.

  1. Recovery step 01

    Don't run it unless you're certain it came from a source you trust.

8 evidence-based answers
Is VdiInst.exe safe, or is it malware?
Evidence-based answer
VdiInst.exe is suspicious — treat it as unsafe until you're sure. No antivirus engine flagged it; the cautious verdict comes from other saved evidence such as identity, prevalence, signing, or runtime signals. Don't run it unless you fully trust where it came from. Get a fresh copy from the developer's official site or an official app store.
What is VdiInst.exe?
Evidence-based answer
VdiInst.exe is a Windows executable program, about 313 KB. We identify a file by its cryptographic hash rather than its name, because the same filename can be reused by completely different files — the hash below is the reliable fingerprint.
How many antivirus engines detected VdiInst.exe?
Evidence-based answer
None — 0 of 76 antivirus engines flagged VdiInst.exe. That's reassuring, though it is not proof that a file is safe, so we also weigh its behaviour, identity, and reputation.
I already downloaded and ran VdiInst.exe — what should I do?
Evidence-based answer
Act quickly. 1) Disconnect the device from the internet to stop the malware communicating or spreading. 2) Run a full scan with reputable anti-malware software (such as Malwarebytes) and quarantine everything it finds. 3) Change your important passwords from a DIFFERENT, clean device — many threats log keystrokes or steal saved credentials. 4) If you bank or shop on this device, watch closely for fraud and alert your bank. 5) For a confirmed infection, the most reliable fix is to back up your personal files and reinstall the operating system for a clean start.
How do I remove VdiInst.exe?
Evidence-based answer
To remove VdiInst.exe: 1) restart into Safe Mode (Safe Mode with Networking if you need to download a tool) so the malware doesn't auto-start. 2) Run a full scan with reputable anti-malware software and let it quarantine or delete the detections. 3) Delete this file from the device, then empty the Recycle Bin or Trash. 4) Check your browser extensions, startup items, and scheduled tasks for anything unfamiliar. 5) Reboot and scan again to confirm it's gone. If detections keep coming back, a clean operating-system reinstall is the most dependable cure.
Is VdiInst.exe digitally signed?
Evidence-based answer
Yes — VdiInst.exe carries a valid digital signature from Tencent Technology(Shenzhen) Company Limited, which confirms the file hasn't been tampered with since that publisher signed it. A valid signature is a positive signal, but note that malware is occasionally signed with stolen or abused certificates, so it isn't proof of safety on its own.
What is the SHA-256 hash of VdiInst.exe?
Evidence-based answer
The SHA-256 hash of VdiInst.exe is b0942f0074abfe3c3f8ea7dc49d775ee9ddb71dd663b007d4d13c83812564cd2, and its MD5 is 89677e0316a0a54fd0eae2d63ceaaace. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
How up to date is this analysis of VdiInst.exe?
Evidence-based answer
This report reflects the scan run on September 24, 2026. Because a file's hash never changes, the identity of VdiInst.exe is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
