norton internet security all desktop icons not working

Just installed norton internet security 2013 on my laptop which runs on window 7. After installing it, none of my desktop icons worked and i could open any programs apart from microsoft office. Has anyone else had this problem or aware if NIS 2013 is incompatible with windows 7. I thought perhaps it was a virus, as i didn't have any antivirus program installed prior to this for a while.

Any help would be appreciated.

Thanks
