Doesn't matter if you're seasoned in fixing other people's machines, it's stupid to not have an anti-virus program. Though a computer literate and cautious user will see more "false positives" than genuine warnings, you never know when an ordinarily trustworthy site has been compromised, a friend sends you something unknowingly that's infected, and so on, so forth.
Your argument is about as valid as someone saying they've had a lot of sex, are careful about picking their partners, and thus, they'll never have to use a condom again. Makes no sense. Experience doesn't protect you.
Furthermore, the better AV programs nowadays, such as Avast, don't take up many resources at all. Computers are significantly faster than they were when everyone's office machine had a slow-as-hell copy of Norton or McAfee. There is especially no good reason not to have a well-designed AV, including others that haven't been mentioned in here (mostly because they're not free), like Kapersky or NOD.
There is no reason not to have an AV, and if you are seriously giving people this sort of advice, you shouldn't be responsible for repairing computers.
Also, you can have both MalwareBytes and Spybot on one machine. Multiple anti-spyware programs is practically always okay, but multiple AV programs is not.
