Symantec Antivirus conrporate edition is not compatible with WIndows 7.
For WIndows 7 you need Symantec Endpoint Protection 11.0;5000 or above

Norton 2010 is compatible with Windows 7.!-674344114!1283455643201

Do you have  Norton Antivirus 2010?

If yes, then please try uninstalling and re-installing...

My current version of symantec is and its installed on Windows 7 and currently is not compatible. Rather buying new version of norton, is it possible to upgrade to new version. There should be an option to upgrade and tried few option too. If try to install 2010 NAV trial version, it works but I need to buy it seperately. With the current version that I have, I need to enable auto protection thats it. I just tried running the live update and with the latest upgrades it could not help to enable auto protection. What would be done..

You can call symantec and ask for upgrade to SEP..
only SEP 11.0.5 and above is compatible with windows 7.

Its not just about enabling autoprotect..thats the main feature of antivirus and its drivers cannot load on windows 7 making it useless on win7

Used Norton for years, loved it.  But this version seems broken.  Have clean installed it several times.  Continually says I have turned off my Norton Antivirus.  I have not.  Continually refuses fo "Fix" Autoprotect.  Gets to point of "Processing" when I engage the "Fix Now" option, but then says "Not Fixed." 

Repeated clean installs aren't working.  I have changed nothing on my fairly new PC since my last issue of NAV.  Now scared to use my PC, am I now exposed to viruses etc??  This NAV is not working?? 

Oh, and I also have to manually go and dig up the Virus Definitions, since NAV 2010 isn't doing that either... (yes its enabled to automatically do so... it just doesn't...)... but since I am continually being told I have turned off my NAV, is that doing any good...? 

S. O. S.

Forgot to mention that also, when I click on my NAV icon, the window that pops up is almost always completely transparent or solid black, exept for the text.  Sometimes it is even partially black and partially transparent, meaning I can see through areas to the desktop.

Rebooting the pc doesn't help either. 

Thanks for any advice.

I have re-reloaded my paid-for 360 repeatedly on my new with NAV Win7 machine.  Is NAV blocking 360?

How stop this endless loop?
