hey all, does anyone have any recomendations for good/safe anti-spyware and cleanup utilities? or more importantly, are there any i should avoid? i'd also like to hear some thoughts on firewall protection! are any free? i am unemployed at the moment, so i need REALLY cheap or freeware. i have noticed that my powerbook has been taking longer to open and was wondering what might be causing it. after doing a little reading, i am paranoid something is messing with mac! thanks in advance! *forgot to include this info: OS X 10.3.9, PPC powerbook G4* PS - stupid question: is it free to upgrade your os?
