Need help in Single User Mode - Avast crashed my computer

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.

 

Yea I wish I could get it to go into safe mode. All it does is start loading the progress bar and then it goes blank and goes back to the grey apple screen and the spinning circle of death.
I posted on the Avast site as well and apparently I'm not the only one but it's still not working yet.

What could be the reasons that it won't go into safe mode? or the repair (command + R)?

 

Bummer - Do you think the following would work? Getting an external DVD drive and plugging it into the laptop to try and boot from that? Given that it's never had a drive hooked up to it, I don't know whether it would recognize it.

 

How do I get Library loaded??

well I followed the advice from Avast which was:
/sbin/mount -uw /
"/Library/Application Support/Avast/install.sh" uninstall
reboot

However I got an error after the uninstall command relating to 2 separate kext unable to find 2 of the files to uninstall them - one of them being the AvastFile Shield.

It's still not loading. Now when I try to do some of the other commands I keep getting this message or versions of it:
