Uninstalling Sophos is not working...

I've had Sophos for about 2 years now through my school, and am literally 8 days away from finishing.

No more than two days ago, I noticed the icon for the shortcut of Sophos was missing - it was just that default windows icon for an executable program now. 

So, I decided I would just uninstall it in case something was wrong and since I was about to graduate from school.  I came to this website and followed the instructions to uninstall it (http://www.sophos.com/support/knowledgebase/article/12360.html).  I uninstalled Alupdate.exe first, just as the instructions said to do, successfully.  Then when I tried to uninstall the anti-virus component, Error 3005 came up saying I did not have Administrator rights to uninstall Sophos.

So I checked the administrator group for Sophos, turns out I do have rights, so I don't know what's going on.

As of now, Sophos anti-virus and remote management system are still installed, but there is no icon in the tray to indicate Sophos is running (even after restaring my laptop), yet I can still access the actual program from the icon on the desktop.  Only Savservice,exe is running, no Almon.exe or anything else Sophos-related.

I would like to remove this program, but I don't know what to do  (I know more than the average person about computers, but I don't feel confident changing too much or anything like that).  Please help me!
