Is acronis-disk-director a Virus or Malware?
The real acronis-disk-director is not a virus. Malware may mimic names to mislead users.
How to Tell if Disk Director is Legitimate or Malware
- File Location: Must be in
C:\Program Files\Acronis\DiskDirector\ or C:\Program Files (x86)\Acronis\DiskDirector\. Any DiskDirector.exe elsewhere is suspicious.
- Digital Signature: Right-click the process in Task Manager → Open file location → Right-click DiskDirector.exe → Properties → Digital Signatures. Should show "Acronis International GmbH".
- Resource Usage: Normal usage is 2-8% CPU and 50-180 MB memory during typical operations. Sustained idle spikes or unusual high usage may indicate an issue.
- Behavior: Disk Director should run during disk operations or when the GUI is actively used. Idle processes without user action could signal malware.
Red Flags: If Disk Director is located in unusual folders (Temp, AppData, System32), runs when Windows is idle, has no digital signature, or uses excessive resources constantly, scan with antivirus software immediately. Beware of similarly-named files like "diskdirector.exe" from untrusted sources.
