maybe there is a problem with the Opera-Installer?

If there are search suggestions, maybe it comes because you have in Alt P, Privacy and Security, a check in, "Use a prediction service to help complete searches and URLs typed in the address bar."
You can test it, but my guess would be that if you delete the file, but keep a check in "Use a prediction service to help complete searches and URLs typed in the address bar," Opera will restart the file.
If you're using Opera 12.16 or earlier, search the Customising Opera forum on how to edit skins. You need to rezip the folder after editing the icons.
If you're using Opera 19, then I don't think the skin can be edited.
