My dad had the same attitude about 10-15 years ago. The printer wasn't working. I found it didn't work because an AV product (maybe even Norton?) was slowing down the printer driver and hit some kind of timeout. I disabled AV. A few months later they fell to a ransomware attack. The name of somebody they didn't know very well but recognized the name of had shown up with an attachment. I wondered if the AV product would have caught it.
