Certain keys on my HP laptops are not working

Hey, so I have two HP laptops, one is a pavilion and the other a note book and basically both keyboards have recently started acting up.

The weird thing is, however, that exactly the same keys on both laptops have suddenly stopped working. The keys I have so far found not to function are "T", "Y", "Ctrl" and "Volume up".

My first thought was maybe the same
Virus has affected both computers as i figured the chances of both keyboards having the exact same keys failing can't be down to chance. So I used malware bytes and ran a scan but found no infections. So I was wondering if anyone else had any ideas on how to fix it?

Cheers
