Toshiba Satellite P105 laptop keyboard/mousepad stop working

Hello…I’m working with a customer who’s
laptop was recently attacked with some malware.
I cleaned it up but for some strange reason
after about 3-5 minutes of use on a reboot the
on board keyboard and mousepad just stop
working. I can plug in an external mouse and
keyboard and it works just fine. Could this be
malware related or just hardware and a huge
coincidence? Thanks.
