I mean, we absolutely did "Free PC Checkups" and obviously we knew how to tinker with startup and do virus and adware removal. These aren't some magical skills that only the rarest of employees knew, it was absolutely basic nerd knowledge that everyone who even applied knew front and back.

Back then of course adware/malware scanners were huge. We certainly did hook computers up and start a bevy of automated scanners and tools and fix performance issues. And every single time it cost a lot more labor and a lot more money to the customer. But it's up to them and a lot of people didn't want a reformat or had a more expensive computer that wasn't as economical to replace.

Believe me when I tell you that productivity wise, a guy reformatting 5 computers at once in an hour flat is lapping anyone who is spending multiple hours per computer running those scanners and tinkering setting by setting.
