Repair or uninstall AVG

If you thing AVG is blocking an application of file, you can add it to AVG exceptions list as described in this article http://support.avg.com/SupportArticleView?urlname=How-to-make-exclusions-from-all-scans-and-shields

Trying to uninstall AVG as I think it is the cause for another program I need for work being partly blocked.
Tried to uninstall it and it wouldn't uninstall…   won;t uninstall and comes up with a general error message.

Thought I'd then try repairing it before trying to uninstall.  It won't repair it and comes up with error message     Oxe0010663

How can I uninstall AVG ?

so now I'm stuck with a partly functioning antivirus… yes it keeps telling me it is out of date yet when I click the update button it says I have the latest version. 

Any suggestions??
