I have had Norton Security Suite for 48 days that I downloaded when I switched to Comcast. This is the first time I have ran into any problems and it says your computer may be at risk. When I try to update the virus definitions none of them update. Can someone please help me out and explain to me why I am running into this problem?   

 

Thank You I greatly appreciatie it.

Just download it manually(20110318-033-v5i64.exe) from http://www.symantec.com/business/security_response/definitions/download/detail.jsp?gid=n95

As an aside

sometimes updates must be installed in a specific order

if that order gets changed as they are downloaded one or more may not install

When this happens I just run live update a second [sometimes a third] time and it fixes the problem
