Running Leopard on my Macbook. I got a notification yesterday that Avast had an update available. So I updated and it asked to reboot. It got stuck rebooting and now will not load. It gets stuck on the grey screen with the apple and the spinning circle. It will not load in safe mode - just get the bar then the forever spiining circle. My optical drive is shot so I can't run the disk repair from that. I've ran in verbose mode and the last item it shows before getting hung up is com.avast.AvastFileShield: Started So I'm guessing that I need to delete/ remove Avast from my system. I can load in single user mode but I'm more familiar with DOS and Windows then Unix and it's command line interface so I need help. I need help navigating to the directory where the program is and deleting it.
