XSS/ BAD BEHAVIOR BLOCK Blocks hacking attempts and automatically bans the hacker access to your website. Recently It seems whenever I log into the oscommerce forums. I see a post stating their website has been hacked. I packaged up what I use to stop XSS and other hack attempts. It should work for most people. No tough requirements. You must have access to your .htaccess (the standard Apache/Linux web server) It is a simple install. One new folder and one addition to your .htaccess file.
