Renaming anti-spyware programs?

I'm not sure renaming before would do any good but it might be safer than waiting.Renaming is pretty simple though,I thought I'd try it just to check.I renamed superantispyware.exe,changed it to superantispywarenow.exe in program files and the registry,went back to program files,double clicked the exe and it opened up just fine.I just right clicked and clicked rename,it gave me no problems.
