105626540bjlvovuo.exe has no authoritative identification as a Microsoft component or named vendor program. Its random-looking name is neither proof of malware nor evidence that it is legitimate, so do not open it to test it. Treat the file as untrusted until you check its complete path, origin, digital signature, cryptographic hash and Microsoft Defender result.
The safest response depends on what Windows is reporting. A downloaded file should be preserved and scanned before execution; a running process should be traced to its path and launch context; a recurring startup message usually points to a stale startup entry, scheduled task, service or relaunching program. The procedure below shows how to investigate and remediate each case without weakening Windows security.

No authoritative indexed source identifies this exact filename as a Windows component, Microsoft utility or recognized vendor application. The name is a sequence of letters and numbers, but naming style alone cannot establish what the file does. Legitimate installers, temporary files and malicious programs can all use unfamiliar names.
Windows executables are identified by more than their names. The useful evidence is the file’s complete location, how it arrived on the computer, which process launched it, whether it carries a valid digital signature, its SHA-1, SHA-256 or MD5 hash, and what a current security scan reports. Until those facts agree, avoid launching or restoring the file.

Why the filename is not enough
- A familiar-looking name can be copied by an unsafe program, while an obscure name can belong to a legitimate installer or temporary component.
- A path in a user-writable temporary or profile directory deserves closer scrutiny, but a path by itself is not proof of malware.
- A missing or failed digital signature is a warning signal, not a complete verdict. Signer, origin, hash and scan results must be considered together.
Is 105626540bjlvovuo.exe safe?
Its safety is unresolved until you examine the evidence. Do not execute it simply to see what happens. Microsoft recommends trusted downloads, current security intelligence, full scans and Microsoft Defender Offline when unwanted software is suspected.
Evidence that should be collected
| Check | What to record | How to interpret it |
|---|---|---|
| Origin | Download URL, email or message, installer name and folder | An unexpected source raises risk; a known installer source still requires scanning. |
| Complete path | Drive, folders and filename | User-writable temporary or profile locations merit closer review, but location alone does not prove maliciousness. |
| Digital signature | Signer, signature status and certificate details | A valid signature can support provenance; a missing or failed signature is a warning, not a final verdict. |
| Hash | SHA-1, SHA-256 or MD5 value | Use the value for Microsoft Security Intelligence lookup or sample submission. |
| Defender result | Detection name, severity, category and file path | A detection should be left quarantined while you follow remediation guidance. |
How do I check the file without running it?
If the file is downloaded but has not been opened, keep it in place, note where it came from and scan it before taking any other action. Do not double-click it, choose Run from a browser download prompt or restore it from quarantine merely because the name looks unfamiliar.
Quick wins for a faster PC:

- Right-click the file and choose Scan with Microsoft Defender. Microsoft Support describes this context-menu scan as a way to check specific files and folders.
- Wait for the result. Keep real-time protection enabled while the scan runs; do not create an exclusion for the file.
- Record the exact detection name, severity, category and path if Defender reports a threat. If there is no detection but the origin remains uncertain, continue with the signature and hash checks below.
Inspect Properties and Digital Signatures
- Right-click the executable and select Properties.
- Review the General tab for its location, size and timestamps.
- Open Digital Signatures, if that tab exists. Select a signature and choose Details to see whether Windows reports that the signature is valid and who signed it.
- Compare the signer with the source you expected. A signer that does not match the download source, or a signature that fails validation, should keep the file in the untrusted category.
Calculate a hash for independent lookup
A hash lets you identify the exact bytes of the file even when filenames differ. In PowerShell, open a window in the file’s folder and run:
Get-FileHash -Algorithm SHA256 .105626540bjlvovuo.exeSave the resulting SHA-256 value. Microsoft Security Intelligence provides hash lookup for SHA-1, SHA-256 and MD5 values and accepts suspicious samples for analysis. Submit only through Microsoft’s service, and follow its instructions about handling potentially sensitive files.
What should I do if Microsoft Defender detects it?
Leave the detected item quarantined. Do not restore it just because the filename is unfamiliar or because a program appears to stop working. Microsoft Defender event 1006, labeled MALWAREPROTECTION_MALWARE_DETECTED, records the threat name, severity, category and file path; those details help determine what launched the file and whether other components remain.

- Open Windows Security and select Virus & threat protection.
- Choose Protection history and open the alert for the executable. Copy the detection name, severity, category and path.
- Allow security intelligence to update, then run a Full scan.
- If the unwanted software persists, restart into Microsoft Defender Offline from the scan options. The offline scan runs outside the normal Windows session, which can help when a component relaunches during startup.
- After remediation, check whether the original application still needs repair or removal. A quarantined executable may belong to a damaged or unwanted parent program.
Do not disable real-time protection to make the file run. Microsoft warns that exclusions stop Defender from checking the excluded item and can leave the device or data vulnerable.
How do I investigate 105626540bjlvovuo.exe when it is already running?
Capture its context before ending the process. The path and parent process often explain whether the executable belongs to a known application or is being launched from an unexpected location.
- Press Ctrl+Shift+Esc to open Task Manager.
- On the Details tab, locate the process with the matching filename. If it is not visible, use the process list and expand likely applications.
- Right-click the process and choose Open file location. Record the complete path before taking action.
- Use Properties at that location to inspect the signature, file version and timestamps. Compare them with the application you believe installed it.
- Return to Task Manager and note the parent or launch context when available. Record this information for a security review.
- If Defender has not already flagged the process and you need to stop a suspicious activity, choose End task only after recording the evidence, then scan the file and investigate persistence locations.
Ending a process does not remove its file or prevent it from starting again. Treat it as a temporary containment step, not a repair.
Why does the error return every time Windows starts?
A recurring dialog can be caused by a stale reference to a file that was deleted or quarantined, a scheduled task, a service or another program that relaunches it. Windows has more than 200 file-system and registry autostart locations on x64 systems, according to Microsoft Press documentation, so checking one startup list is not always enough.
Check Startup apps
- Open Settings and go to Apps > Startup.
- Look for an entry whose command, publisher or path references the executable or an unknown parent program.
- Turn off an unrecognized entry rather than deleting it. This is reversible and lets you test whether the message stops.
- Restart Windows and observe whether the dialog returns. Rescan after the reboot.
Inspect Task Scheduler
- Open Start, type Task Scheduler and launch it.
- In Task Scheduler Library, review tasks and their Actions tab. Look for commands that point to the filename, its folder or an unfamiliar script.
- Check the task’s triggers and author. Disable an unrecognized task first; do not delete it until you have preserved its name, action and location.
- Restart, scan again and re-enable the task if evidence shows it belongs to a legitimate application.
Review services and other autostarts
Open services.msc and inspect services whose executable path includes the file or its parent directory. Use Properties to record the service name, startup type and path, then stop and disable an unknown service only as a reversible investigation step. Also review login scripts, browser extensions and installed applications that may recreate the file.

Microsoft’s Autoruns documentation covers the broad range of file-system and registry locations used for autostart. If a normal Startup list and Task Scheduler do not explain the relaunch, use Autoruns to locate the exact command, then uncheck an unknown entry rather than deleting files blindly.
How do I fix a 105626540bjlvovuo.exe error when no threat is detected?
The filename alone does not identify a specific Windows error code. First capture the exact dialog text, event ID, full path, signer status and whether Defender quarantined anything. Different messages require different repairs.
If the file was removed or quarantined
The dialog may be a stale reference from an application that expects the missing executable. Open Settings > Apps > Installed apps, find the parent application if you can identify it, and choose its repair or uninstall option. Reinstall only from the publisher’s trusted source after the system is clean. Then remove or disable the stale startup, task or service entry that still points to the old path.
If the message names a missing DLL or dependency
Do not download a replacement DLL from an unverified “DLL” site. Identify the parent application from the path and dialog, repair or reinstall that application through its official distribution channel, and scan the installer before running it. A missing dependency can be a software-integrity problem rather than evidence that this executable itself is safe.
If Windows shows an application or runtime crash
Record the Event Viewer entry, including the faulting application, module and event ID, then compare the timestamp with the executable’s launch. Update the affected application and Windows through their normal update channels. If the crash persists after Defender scans and a clean reinstall, use the application’s support process; generic repair utilities cannot establish the executable’s identity or guarantee that a crash will be fixed.

Should I delete 105626540bjlvovuo.exe?
Do not delete it solely because the name looks random. Deletion can break a legitimate application, remove evidence needed for analysis or leave a startup entry that continues producing errors. Quarantine is safer when Defender has detected a threat, while disabling an unknown autostart entry is safer than deleting it during investigation.
Before manual deletion, preserve the path, hash, signature information, detection name and the exact error text. If the file is confirmed unwanted and no legitimate parent application needs it, remove it through Windows Security’s remediation or the parent application’s uninstall process. Rescan after removal and check for relaunching tasks or services.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Which remediation choice is safest?
| Option | Evidence quality | Reversibility | Protection impact | Persistence coverage |
|---|---|---|---|---|
| Defender quarantine and full scan | Uses Microsoft’s detection name, severity, category and path | Quarantine preserves a recovery decision without executing the file | Keeps real-time protection active | Follow-up checks are still needed for tasks, services and startup entries |
| Disable an unknown startup or task | Requires you to verify the command and path | Easy to re-enable while testing | Does not require an exclusion | Addresses that specific relaunch point |
| Delete the executable immediately | Weak if based only on the filename | Hard to undo and may destroy evidence | Can leave protection unchanged but may break software | Does not remove other launch entries |
| Microsoft Security Intelligence hash or sample submission | Adds external analysis to local evidence | Preserves the local file for controlled submission | Does not require disabling Defender | Identifies the sample but does not itself remove persistence |
What information should you include when asking for help?
Provide the exact error text rather than paraphrasing it. Include the full path, whether the process was running, where the file came from, the signer and signature status, the SHA-256 or other hash, the Defender detection name and the event ID. Do not upload personal documents or confidential data merely to obtain a second opinion; submit a suspicious executable through Microsoft’s designated security channel and follow its handling instructions.

What is the final verdict on 105626540bjlvovuo.exe?
The executable cannot be called safe or malicious from its filename alone. Keep it untrusted, collect its path, origin, signer and hash, scan it with Microsoft Defender, and use quarantine or reversible autostart changes before considering deletion. A recurring error should be treated as a persistence or stale-reference problem until the exact dialog and launch point are identified.

Frequently Asked Questions
Can I upload 105626540bjlvovuo.exe to a public malware scanner?
Check the scanner’s privacy policy before uploading because samples may be shared with security researchers or other users. If the file could contain proprietary code or personal data, submit its hash first or use Microsoft’s security-submission process instead.
Recommended Free Tools
What if the file disappears before I can inspect it?
Check Windows Security Protection history and the original download folder. A quarantine record can preserve the path and detection details even after the file is no longer visible in File Explorer.
Could a legitimate game installer have a random executable name?
It is possible, especially for temporary unpacking components, but legitimacy still depends on the publisher, download source, signature and scan result. Verify the installer through the game’s official distribution channel rather than trusting the filename.
Will System Restore remove the problem?
System Restore can change system files and settings but is not a substitute for a malware scan or persistence review. If you use it, continue checking Defender history, startup entries, scheduled tasks and services afterward.
