1. Change to PHP 5.3 and update your Drupal installation to the most recent version. This can be done in the PHP Config section of the cPanel.
Simply click on the radio button to the left of PHP 5.3 or PHP 5.3 Single (depending on which php.ini behavior you prefer) and then save the changes.

2. You may also disable magic_quotes_gpc in the php.ini.
This is done by finding the php.ini that applies to your Drupal installation in the File Manager, and Editing it.
Once inside, search (the ctrl+f find function is recommended) for the line magic_quotes_gpc=On and set this variable to magic_quotes_gpc=Off

I'm on BlueHost and I experienced the problem on an updated installation of D7 and D6. It was very annoying, and the fact that Drupal automatically turns it off really made it difficult to diagnose. Sadly, Drupal's attempts to turn it off failed, and I needed to edit the php.ini file in the server root to turn it off. Simple enough, but it sure was a pain to figure out. It's all better now, though.

I'm on BlueHost and don't see a problem yet. I've a D6 site that is aggregating RSS into nodes and they are usually filled with quote characters.
