Icons Misdirected

This morning I noticed that some of the icons on my office shortcut toolbar
were misdirected. The calendar, task and Word icons were fine, but others
directed me to the wrong program. This may have been caused by a power
surge last night. My UPS might not have functioned correctly.

I can establish them correctly by adding the executable file and the icons
are correct. But when I try to delete the bad icons I get a message that it
will delete the programs and all the files associated with the program.

Any suggestions?
