Douglas…please don’t be mad but this gave me a hearty laugh because much the same happened with me…it was totally unexpected, I jumped in surprise which scared my dogs who then started barking and that scared the cats and all four of them would not go near the computer for days (I’m used to at least one of the cats helping me type).
OMG! It’s not me wreaking havoc on my computer!! It’s my cats ;D

" I have to say though, the included voice announcements in Avast, scared the Hel* out of me the first time the virus defs auto loaded. I have some 5.1 surround speakers on my system that were turned up during my first virus def update."
