Hello all, I'm a proud owner of a G4 Powerbook - bought brand new back in the early '00s. I don't regret for a moment the $2k I spent on it. It has paid for itself and more. However, I wonder sometimes if over the years I have picked up some malware or a virus of some kind? I tried installing ClamXAV, but it didn't work. I'm running 10.4 Tiger. I downloaded an activity monitor, and I don't see anything unusual hogging up the CPU, although I don't recognize the majority of processes going on. I'd like to keep this old Powerbook going another few years. Curious if you guys/gals knew of anything to check the health of my machine? Thanks for any advice!
