I have an HP Pavillion 13 which I bought about 2 years ago. Recently while using it, I saw that my touchpad stops working suddenly. When I open the device manager, I see that the driver for the Mouse (Synaptics) has been uninstalled. I download the driver from Internet, install it, restart my computer and my touchpad starts working perfectly again.
Now, after a few hours of work, the same issue pops up again.
I tried performing a clean installation of my Windows (remove all personal files) and the problem seemed to go away for while, but after few hours, same issue repeats.
I am running Windows 10 but the laptop originally came with Windows 8.1 pre-installed in it.
Is my computer infected by a virus?
