A couple months ago, I was trying to install something. A pop up advertisement for an anti malware program named “ByteFence” showed up and it installed itself. I tried to delete it but it wouldn’t go away. After, my laptop started to lag and freeze so I shut it down. Once I turned it back on, my touchpad and keyboard were both not working. My wireless mouse does still work, though. I try to use to screen keyboard but that won’t work either. Does anybody know how to fix this?
