Quick Answer
scandriver.exe is safe. It is a protected driver component of the ScanDriver antivirus suite that coordinates scanning, updates, and protection tasks in the background.
Is it a Virus?
✔ NO - Safe
Must be in C:\Program Files\Scandriver\scandriver.exe or C:\Program Files (x86)\Scandriver\scandriver.exe
Can I Disable?
✔ YES - Disabling may reduce protection and allow threats to go undetected
Disabling real-time protection may leave the system vulnerable to threats and reduce detection capabilities
What is scandriver-exe?
scandriver.exe coordinates the scanning engine and file indexing for real-time protection within the antivirus suite.
Driver is part of the protection stack and coordinates scanning tasks
What is scandriver.exe?
scandriver.exe is the driver component for the ScanDriver protection software. It coordinates the scanning engine, threat-definition updates, and indexing tasks for real-time and scheduled scans. It runs in the background with elevated privileges to access files and system resources to protect the host.
The driver enables the protection engine to inspect files and memory safely while coordinating updates, scheduling, and task distribution across worker processes to maintain responsiveness.
Quick Fact: scandriver.exe often runs as multiple background threads within the protection stack to isolate scanning tasks from the user interface, improving protection and stability under heavy workloads.
Types of ScanDriver Processes
- Driver Service: Core service coordinating scanning operations and exposing protection APIs
- Scan Engine Worker: Per-file or per-folder scan operations
- Update Service: Definition and engine updates
- Scheduler: Schedules scans and maintenance tasks
- Telemetry/Reporting: Sends anonymized protection telemetry to vendor servers
- UI Bridge: Bridging between system tray UI and protection engine
Is scandriver.exe Safe?
Yes, scandriver.exe is safe when it is the legitimate file from Trend Micro Incorporated installed via official channels (vendor installer or Windows Update).
Is scandriver.exe a Virus or Malware?
The real scandriver.exe is not a virus. Malware may masquerade with similar names. Always verify the file path and digital signature.
How to Tell if scandriver.exe is Legitimate or Malware
- File Location:: Must be in
C:\Program Files\Scandriver\scandriver.exe or C:\Program Files (x86)\Scandriver\scandriver.exe. Any scandriver.exe elsewhere is suspicious.
- Digital Signature:: Right-click the file in File Explorer -> Properties -> Digital Signatures. Should show vendor like Trend Micro Incorporated and a valid timestamp.
- Resource Usage:: Normal usage is 2-12% CPU and 50-200 MB memory during scans. Sustained high usage when idle is suspicious.
- Behavior:: The driver should run only when the protection engine is active; persistent startup without antivirus activity could indicate malware.
Red Flags: If scandriver.exe is located in unusual folders (e.g., C:\Windows\Temp, AppData\Local, or System32), runs when protection is off, lacks a valid digital signature, or uses excessive resources, scan with your antivirus. Look for similarly-named files like "scandriver64.exe" from untrusted sources.
Why Is scandriver.exe Running on My PC?
scandriver.exe runs as part of the antivirus protection stack to coordinate scanning tasks, update threat definitions, and support real-time protection. It can start with Windows, run in the background, and spawn worker processes for individual tasks.
Reasons it's running:
- Active Protection: The protection engine is actively monitoring files and processes, so the driver starts and runs workers for real-time checks.
- Background Updates: Definition updates and engine improvements run in the background to keep threat detection current.
- Scheduled Scans: Automated scans are queued and executed by scandriver.exe according to the schedule set in the antivirus app.
- Real-time Scanning: As you access files, real-time scanning tasks are distributed to worker threads spawned by scandriver.exe.
- Post-Install / Post-Update: After installing or updating the protection suite, scandriver.exe may initialize components and reindex for protection accuracy.
Can I Disable or Remove scandriver.exe?
Yes, you can disable scanning features, but doing so reduces protection and may expose you to threats. Prefer disabling features within the antivirus settings rather than deleting the file.
How to Stop scandriver.exe
- Pause Real-Time Protection: Open the antivirus app and toggle off real-time protection to suspend scandriver.exe activity temporarily.
- End scandriver.exe Processes: Open Task Manager (Ctrl+Shift+Esc), locate scandriver.exe under Background processes, and End Task if allowed.
- Disable Startup: Open Services (services.msc) or Task Manager -> Startup tab, find the ScanDriver service and set Startup type to Disabled.
- Adjust Protection Settings: In the antivirus settings, disable modules such as real-time scanning or cloud protection that rely on scandriver.exe.
- Consider Uninstalling the Suite: If you want to remove scandriver.exe entirely, uninstall the antivirus package from Windows Settings -> Apps -> [Vendor] Antivirus -> Uninstall.
How to Uninstall scandriver
- ✔ Windows Settings -> Apps -> Apps & Features -> [Vendor] Antivirus -> Uninstall
- ✔ Control Panel -> Programs -> Uninstall a program -> [Vendor] Antivirus -> Uninstall
- ✔ Follow vendor prompts to complete removal; reboot if required
Common Problems: High CPU or Memory Usage
If scandriver.exe is consuming excessive resources or failing to start, try these targeted steps to restore normal operation.
Common Causes & Solutions
- Ongoing full-system scans: Pause scans or schedule heavy scans during idle times
- Conflicting security software: Temporarily disable other security programs or set exclusions
- Outdated definitions: Update definitions and engine to latest version
- Multiple real-time modules running: Disable redundant protection components within the antivirus settings
- High memory usage from indexing: Limit or optimize indexing schedules and exclude large folders
- Malware or PUP interference: Run a full system scan with updated definitions and remove any threats
Quick Fixes:
1. Open the antivirus Task Manager and identify active scanning tasks
2. Pause or cancel long-running scans
3. Clear cache and temporary data used by the protection engine
4. Disable unnecessary modules (e.g., cloud protection) and extensions
5. Update to the latest antivirus version
6. Restart the computer to reinitialize services
Frequently Asked Questions
Is scandriver.exe a virus?
Not typically. The legitimate scandriver.exe is part of the antivirus protection stack and should reside under C:\Program Files\Scandriver with a valid digital signature from Trend Micro Incorporated or the vendor who supplied the protection suite.
Why does scandriver.exe use so much CPU?
CPU usage increases during active scans or when real-time protection is analyzing many files. If usage stays high when idle, check for conflicting software, a stalled update, or malware masquerading as scandriver.exe.
Can I uninstall scandriver.exe without removing the antivirus?
No. scandriver.exe is a component of the antivirus protection stack. Removing it typically requires uninstalling the entire antivirus package.
Where is scandriver.exe located?
The legitimate file is usually at C:\Program Files\Scandriver\scandriver.exe or C:\Program Files (x86)\Scandriver\scandriver.exe. If you find it elsewhere, investigate its digital signature and vendor.
How do I update scandriver.exe or the protection engine?
Update through the antivirus application’s update mechanism or the vendor’s official updater. Keeping the definitions current is essential for effective scanning.
Can scandriver.exe run when the antivirus is disabled?
If the antivirus protection is disabled, scandriver.exe should not actively scan. If it does, this could indicate a misconfigured or compromised installation; run a full malware scan and verify the vendor installation.
