I got this from my hosting site

I have checked your site and found the following suspicious files:

Code:
[STR]Hacked_by_string : [17/09/13] /home/obglobal/public_html/admincp/plugin.php
[STR]Hacked_by_string : [17/09/13] /home/obglobal/public_html/admincp/help.php

Please check and clean them if necessary.

Any ideas on what I should do?

Delete these files:
admincp/black.php
admincp/nsuser.php
admincp/admin.php

^ Those files are not included with vBulletin by default. Replace the other files by overwirint them with 100% fresh files as ForceHSS mentioned above .
