Missing all Applications except Skype and finder

[jlepfaff]

For some reason, when my son was trying to load a from a CD to the applications folder all the applications suddenly disappeared. If you click on itunes or word you get an error notice about a corrupt file. The documents appear to be there. What should we do? We are running OS 10.4.11 on an iMac.

Thanks
