Laptop Symantec Endpoint Protection

To anyone who can assist,

I am running Symantec Endpoint Protection Version 11.0.3001.2224 on my 'laptop' and have an error with a scan recently completed.  I know that my files are corrupt as I have tmp files in my "Incomming Folder".  When I went online to find out how to correct the issue, it only provide me a solution for v 10.xxx and it only provides how it can be corrected via the Symantec System Center.  How can i revert to the previous definition set while working remotely on my laptop??

Regards
