I have Leopard 10.6 installed since beginning (have had computer for 4 weeks) I can't save changes to iTunes 8.0, iLife 09 /iMovie, iPhoto. I throw things in the trash then when i reboot the stuff is back in the programs. I try to create changes to movies ie transitions or audio ; the next time i enter /post reboot, the changes disapear as if i never did anything. this has been going on for weeks. could i have a virus... how can i check if malware is in system? do i have to do something with permissions, plist (i am pulling at straws) when i talk to Apple , they give me that "audio stare" as if i am crazy. Please someone with technical ability throw me a bone.
