We had a customer in lately with a machine that had been trashed by their kids. Lots of malware, pirated software, torrents.. You name it. Cost to repair? Well, the machine needed to be replaced. $690….. Plus a few thousand for a new copy of their accounting software since they didn’t have the disks and most likely 2-3 hours of onsite labour @ $85.00/hour to get the whole thing back up and running on their network. They’re now down for a few days while the new machine arrives.
An expensive lesson: Don’t let your kids touch your business PC. In fact, don’t let anyone use it for anything other than business related activities.
