Adobe Reader could not open 'firefox.exe'

adobe reader could not open 'firefox.exe' because it is either not a supported file type or because the file has been damaged. for example, it was sent as an email attachment and wasn't correctly decoded. this is what my new laptop says. It worked since i got it 1 month ago. now it suddenly does not let me get on firefox internet,but my desktop has no problem. can anyone help me get the internet back on my laptop???
