Windows Security Alert/NIS 2009

Using XP and NIS 2009

 

Windows Security Alert shows as a red shield in the bottom right corner and tells me that the virus protection is turned off. NIS 2009 tells me everything is on and protected.   I went online and did a chat, and was basically told the problem was with MS and not with Symantec.

 

Problem only started after downloading windows updates this week.

 

Any ideas how to fix?
