Safari, Itues, MSN and Update-programm doesnt open anymore!

Question

Hey Apple-Team!
I have a unusuall problem.
Yesterday my mac requested me to turn it off, during i was installing a safrai update. when i switched my mac on again, i was unable to use any programm that uses the internet!!
My Airport ist active and shows that i have a great singanl ! but any application/programm such as safari itunes etc. doesn`t opne anymore. when i click on the symbol eg. the safari symbol it jumps up and down for 5 second as usually but then it stops and does nothing. in other words the programm doesn´t open anymore.
Moreover the softwareupdater doesnt upen too (i quess its caused by the same problem, that no programm that uses the internet doesn`t open anymore"
thankfull in advance yours Helpseeker
Ps: i am just 19 years old and not a prodigy concerning mac etc. so please use a "freshman" explination!

Welcome to the Apple forums. There is no one from Apple here: we are all users like you and offer suggestions depending on what information we have. Unfortunately from your description, you have had a kernel panic (KP). The computer or OS has had a problem and stopped. Most can be fixed easily, although some may require a bit more work.
If your reading English is up to it, try Doctor Smoke's FAQ on Kernel Panics as there are several useful ideas there. (Buy his book if you can.)
You have restarted and there are problems, so I would suggest a restart with the grey install disk. Select the language then use the menu at the top of the screen to access the Utilities and the application, Disk Utility. Repair the disk.
If you have added RAM recently, that can sometimes be a cause of the KP so removing/replacing that might help (if that is a cause).
It might be helpful as this is internet related if you use Network preferences and create a new Location. Perhaps if you are using "Automatic" there are some settings/data in there that may be causing conflicts.
It might also be useful to create a new Admin account and to work from there (if the other account has problems). Until you can safely use Safari (it is not properly downloaded and the old version is compromised) try to use Firefox or another browser.
In the username>Library>Preferences folder, there are files that end in .plist (property list), find those for Safari, and put them in the Trash.
Try these things and come back to the forum and let us know how it went. If my words are not clear (I know there is a lot here) come back and we will try and explain in another way.
