Trojan
 

i guess there was on my forum and i guess through that it was able to log into cpanel and etc....and certain things arent working anymore like the shoutbox and you cant click on certain things, i had the server host run a scan and they took care of everything and i changed all passwords but they obviously didnt fix the forum

how can i go about fixing up my forum?

About the shoutbox it will be best if you asked at its own thread.

Also it would help if you give a detailed descriptions of what is not working on your forum rather then giving a general and very vague discription like "and you cant click on certain things" etc. We are not mind readers you know :D

well basicially nothing is working

shoutbox wont load
cant click on smileies
where it used to say community and have member list has all changed and split up
profiles look different

A virus did not attack your forum I don't think, It attacked and got into your computer. And then it logged into your site and made a mess.

How to restore from something like this? Backups.

Backups are your friend. Update them often and protect them with your life. Take them to lunch once in a while even, and they'll thank you for it when you need them most.
Like right now for instance.

Backups are a friend you can count on.

Can you post the links to those area with issues?

As stated above, restore your most recent backup. Also it won''t hurt to check thoroughly your server space and/or db. And let your host know about it so they can check the access logs and see exactly what went down at your forum.
