I've had Bullguard on for quite a while now... and it will operate ok for about a couple of hours maybe, until suddenly all my internet pages will display 'cannot find server' and i'll be logged out of Messenger etc. I then have to restart the computer. I know it is Bullguard that is doing this, as when I uninstalled and placed another antivirus/firewall on, I had no problems at all.

 

Do you know why it does this?
