- Right-click on the antivirus software icon in the System Tray (near the clock) and select "Disable".

- Wait 5-10 minutes and then enable it again.

Check for Malware: Run a full scan with your antivirus software to detect any malware that might be causing issues.

Update Windows to the Latest Version: Ensure you have the latest Windows updates installed, as this can help resolve some installation problems caused by antivirus software.

- Check for any recently updated drivers or services and disable them if necessary.

- Press the Windows key + R to open the Run dialog box, type "sfc /scannow," and press Enter.
