I understand how worrying it is to feel like someone might be controlling your laptop and causing files to disappear. Have you already tried the Q&A Assist suggestions? In addition, please try the following:
1, Unlink your phone temporarily
- Go to “Settings” > “Bluetooth & devices” > “Mobile devices” (or “Phone Link”)
- Select your phone and remove/unlink it > This helps confirm whether the issue is tied to syncing or the PC itself.
2, Check for unknown apps
- Go to “Settings” > “Apps” > “Installed apps”
- Look for anything you don’t recognize (especially tools like AnyDesk, TeamViewer, Chrome Remote Desktop, etc.)
- If found, select it > “Uninstall”
3, Run Microsoft Defender Offline scan
- Open “Windows Security”
- Go to “Virus & threat protection”
- Select “Scan options” > “Microsoft Defender Offline scan”
- Start the scan (your PC will restart) > This can detect deeper threats that normal scans may miss.
4, Check startup programs
- Press Ctrl + Shift + Esc > Task Manager
- Go to “Startup apps”
- Disable anything unfamiliar or suspicious
