I have Norton Internet Security and have run 3 full systems scans since Friday, run all of the system tools and diagnostics daily, get my Vaio and Windows updates automatically, including all drivers, and my daily system tools updates includes the System File checker, disc/registry cleaners and defrag programs and I don't know what a reinstall of the OS is but that sounds like you might lose everything such as settings etc. I don't have Malwarebytes in this computer too as I did in my old one because it used to fight with Norton and cause me problems.
Don't you think uninstalling/reinstalling the touchpad driver and then getting the driver updates might be something to try first before the OS work and installing another virus/malware hunter? What if it is something that simple? A corrupted driver could cause the touchpad to stop working properly couldn't it? Has anyone ever done it in Windows 7? And did you have a copy of the driver on CD or jump drive before you tried it?
