Problem NAV

Hi, This is the 3rd. that i get this problem.

 

Autoprotect --- No fixed

SONAR --- No fixed

Antispyware --- No fixed

e-mail protection --- No fixed

 

I solve this problem using the tool NRnR, but i think is not the problem, the problem is why happend?. I dectected this problem once when i put the NAV inactive for 15 minuts that was the 1st. time, the 2nd. and 3rd. after detected and delete a virus.

 

Thanks.
