Microsoft Issue

Question

The cursor moves on its own and the pop ups won't stop

Answer 1

Hi, I'm Bernard. I'm happy to help!

Is there a chance that you can provide a clip, recording, or screenshot of the issue so I can point out the main problem? While waiting, I recommend disabling unnecessary services in the background, then check it again.

Do a clean boot:

A “clean boot” starts Windows with a minimal set of drivers and startup programs, so that you can determine whether a background program is interfering with your game or program.

• In the search box on the taskbar, type msconfig and select System Configuration from the results.
• On the Services tab of System Configuration, select Hide all Microsoft services, and then select Disable all.
• On the Startup tab of System Configuration, select Open Task Manager.
• Under Startup in Task Manager, for each startup item, select the item and then select Disable.
• Close Task Manager.
• On the Startup tab of System Configuration, select OK. When you restart the computer, it's in a clean boot environment.

This behavior is consistent with malicious or scam pop-ups in the browser rather than Windows itself being “taken over.” To stop it and reduce the chance of it happening again, follow these steps:

1. Close the malicious pop-up when it appears
   • Press Ctrl + Alt + Del.
   • Select Task Manager.
   • In Processes, select the web browser (for example, Microsoft Edge or Google Chrome) that shows the pop-up.
   • Click End task to close the browser completely.
2. Block intrusive pop-ups and redirects in the browser In the browser settings, disable pop-ups and redirects and block misleading ads so these scam pages are less likely to appear again. (Exact steps vary slightly per browser.)
3. Remove suspicious extensions
   • Open the browser’s Extensions or Add-ons page.
   • Remove any unfamiliar or recently added extensions.
   • Restart the browser.
4. Run a full malware scan
   • Open Windows Security.
   • Go to Virus & threat protection.
   • Choose Scan options → Full scan and let it complete.
   • Follow any remediation steps offered.
5. Treat any “support” pop-up as a scam
   • Microsoft does not display phone numbers in pop-ups or lock the PC asking to call.
   • Do not call any number shown.
   • Do not allow remote access or install software requested by such pop-ups.

If the cursor still moves on its own after all browsers are closed and after a full malware scan, disconnect any external pointing devices (including wireless dongles) one by one and test again, as faulty or compromised input devices can also cause unwanted cursor movement.
