Norton 360 invisible

Hi

just installed norton 360 on to my laptop, windows 7. norton is open as i can see it on the task bar and that it has 2 screens open but they are both invisible.

i have uninstalled and reinstalled, checked the disks through command, played with the graphics and nothing works, i tried the norton NPE from the website but that is also invisible.

Ive only just removed lots of malware from the laptop (my husband doesnt know about anti-virus!!) so dont want it unprotected so still have Mcafee on it too. but i tried this beforehand and had the same invisibility issues

 

Any ideas??
