You aren't going to learn how to secure anything. Instead you're going to start with fresh software or fresh pages, on a fresh host. That leaves the vulnerability and exploit behind.
>>Also would using some like this be useful for creating a more secure .Htacess file?
Are you even reading this thread? The answer is no. Your htaccess file is not for security.
>>Is a password or blocking a ip address or range of ip's a viable solution?
Again, did you read the multiple posts in this thread about this? The answer again is no. Either find the vulnerability - and you can't because that takes a pro, or start with fresh software on a fresh host. You are not going to recieve an answer like 'they came in through this file, and therefore if you change line 18 the problem will be fixed'.
