Installing AVG Internet Security

Hi Terje,
Sorry to know that. This issue can be fixed by using the AVG Reset Access tool. Please follow the steps in this article to get this issue fixed ( http://support.avg.com/SupportArticleView?urlname=Message-Verify-that-you-have-sufficient-privileges-when-installing-AVG ).
Please do not hesitate to get back to us for further assistance. Thank you.

When I try to install AVG Internet Security the process stops at this message "stopping services" under the process bar. Then after a while I get another message "Service 'AVG Firewall' (avgfws) could not be stopped, Verify that you have sufficient privileges to stop system services." 

Can anyone hgelp me?
