PHP Warning Module phpSHIELD already loaded

Hello all. I happened to check the error log in my wordpress directory on my sites (all using the latest wordpress 3.3.1) and i noticed the following error.

[29-Feb-2012 15:55:38] PHP Warning:  Module 'phpSHIELD' already loaded in Unknown on line 0
[29-Feb-2012 20:55:38] PHP Warning:  require(/home/acct1/public_html/mydomain.com/wp-includes/load.php) [<a href='function.require'>function.require</a>]: failed to open stream: No such file or directory in /home/acct1/public_html/mydomain.com/wp-settings.php on line 21
[29-Feb-2012 20:55:38] PHP Fatal error:  require() [<a href='function.require'>function.require</a>]: Failed opening required '/home/acct1/public_html/mydomain.com/wp-includes/load.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/acct1/public_html/mydomain.com/wp-settings.php on line 21

Judging by the size of this error log and the amount of times the error is repeating, it looks as if the error is occuring whenever someone visits my site.

If anyone has any idea what might be causing this I would appreciate your help. Thanks in advance.
