i am the owner of a mac g3 that us currently running Os 10.3. My problem started when i was told by my browser that it would no longer be supported because of my outdated operating system. I foolishly had been downloading music form a site i thought secure and i was also under the impression my computer was too old to get a virus. But since i downloaded a new browser "Opera" (which i thought was secure since it was a Mozilla product) my computer has been acting up a lot. And recently (through the use of our router) i found that my computer was connecting to sites i was not visiting. Now what i would like is to wipe out my computer and get a new FREE linux operating system. But i am not sure about how to do it. I have never wiped out a computer before nor ever installed an operating system. Can any one please help this non tech person? THANK YOU!
