Cannot run Safari, iTunes, anything involving WebKit and JavaScript frmwks

Question

Ok this seems to be an issue that plenty of people are having or have had. This happened to me after I tried to update Safari. I did the Safari update then updated from 10.3.9 all the way up to 10.4.11 and I cannot load pretty much any apps and like everyone else I have to use Firefox for the internet. I have repaired permissions, verified the drive, tried 'sudo softwareupdate -i -a' from Terminal and every other fix posted. I cant even run AppDelete to remove Safari as to try and reinstall it becaus e I get the same error as everything else. Console reports the same error for every program that I try to run that bounces twice and goes away and does run. I cant even use Adobe Reader 8 or install any of my Creative Suite for work. I've been Googling and searching for weeks now; I don't have the means to purchase an external device and backup everything and reinstall with a clean install which I'm sure is the end all be all fix so I am really hoping there is a fix or someone has overcome this problem in a manner which I can use. Here goes... The infamous error is:

All the same error!!! This is my very first Mac and any help would be greatly appreciated because I still have to use my PC just so I can listen to my music!

Welcome to the forums!
I'm wondering why so many people haven't had this problem!? I haven't on about a coule dozen updates to 10.4.11.
Are you using the big Combo Updates when you do it, or the little Delta updates?
It seems Java is involved in this too, here's just the files in System where I found that Symbol"ZN3KJS11Interpreter4markEv"

I'd try reapplying the 10.4.11 Cobo Update & the Latest Java updates for a start.
