Clean Up and securing Code.

I have a php social community script that has some bugs, seems to be spammed or hacked and needs to be more secure. I'd like someone to clean up the coding and make the script more secure for me. The website is: w w w . a r k l a t e x l i v e . n e t without spaces .. Let me know what can be done .. You will notice the users: happy and makous, these users I have no clue how they got there, but I think it's either some kind of spamming tool or hack. The script is a script I bought back a few years ago. The company decided to stop development and gave everyone who purchased it, unlimited license. I'd like very much if you could Find & Replace everywhere there is Joovili and make it Social. So that if there is a spam search for Joovili, it will not find where I install in the future. I'd like if you could make the User Signup and Once Logged In, be Https that will work with servers that have SSL, I'd like the script fixed so it works right, The Youtube Video Upload needs to be written into the DB as everytime I install, I have to manually go into Phpmyadmin to add the following code: ALTER TABLE `WebSocial_videos` ADD `video_type` VARCHAR( 10 ) NOT NULL DEFAULT 'UPLOAD' AFTER `video_date` ; so that the Youtube upload works You will notice the script has somewhat of a captcha, so we would assume that it's not a bot that's making the fake accounts, but there must be some kind of software that breaks the simple captcha and creates these fake accounts. You can see the same script being used here: [login to view URL] and you will see that it has been overrun by these fake accounts. Basically rewrite or find & replace the install or database so that there is no more Joovili and Joovili is replaced with Social .. I think the spammers or hackers maybe doing a search for the word or the script and that helps them to get the Fake Users Created, so to be safe, remove the word Joovilie from the entire script ..
