I need help to uninstall my “Adobe Reader 10.1.1” on my Mac

Hello TechyV,
I need help uninstalling my “Adobe Reader 10.1.1” on my Mac. My Mac runs on OSX 10.6.8. I can’t open PDF using Adobe Reader and it just gives out the error: "There was an error opening this document. The file is damaged and could not be repaired".
I don’t have this problem opening this document on my other Mac book. Putting Adobe Reader in the trash and then reinstalling didn’t help. Previewing shows the contents of the same files that Adobe won’t open. Could someone please help me uninstall Adobe Reader 10.1.1 from my Mac?
Thanks in advance.
