You can use the PHP function stripslashes ( 
http://php.net/manual/en/function.stripslashes.php ) to remove them.

WordPress has one also, stripslashes_deep ( 
http://codex.wordpress.org/Function_Reference/stripslashes_deep#Basic_Example 
) to go through arrays and strings.

I believe this happens when magic_quotes_gpc is enabled ( 
http://www.php.net/manual/en/info.configuration.php#ini.magic-quotes-gpc 
) So you could also disable this behavior if it's unwanted (
