Hi,
Please open Task Manager->Process Tab->Right click on the Synaptics Pointing Device Driver entry and open the file location.
Is it located outside of C:\Program Files?
If yes, there's a good chance that it's a malware. Download Malwarebytes and scan your PC to get rid of it. Also do run a scan using Windows Defender.
Even if it is there in the C:\Program Files, run the scans to make sure that it isn't a malware.
