In a Mutants & Masterminds game, I played an Amazonian warrior from a lost civilization (think Wonder Woman for the closest comparison). Since her people used "magitech," she wasn't familiar with modern technology.
During one adventure, she tried to do an Internet search (long story), and the "Your computer may already be infected!" popup ad appeared.
For a number of days afterward, I had her go around the team's base spraying Lysol on all the computers. When another character inquired why she was doing that, she replied, "The computer said that it may already be infected." Indicating the Lysol, she continued, "This is disinfectant; shouldn't that solve the problem?"
I think that amused everyone in the group, including the GM. :)
