Apple has not yet released a fix for the hole, so at the moment third parties like Symantec are suggesting various fixes... including uninstalling QuickTime. I doubt many will go to such lengths, but with people even suggesting steps that drastic perhaps Apple should accelerate the release of a patch.
QuickTime has been receiving a lot of bad press this year. It has had numerous flaws discovered, many of which are severe security vulnerabilities. As it is a cross-platform application it has the potential to be more of a threat and thus is getting more bad attention, but likely the increased success of OS X since its inception has a lot to do with it. Apple cannot afford to delay on getting fixes for these vulnerabilities out. Unless, of course, they want to be in the same boat as Microsoft.
