Security alert-Antivirus is turned off, although it is not

In task bar security alert is giving me a message that avg antiviurs is turned off
while I still see avg icon in taskbar (so it is running) and also when i double click on avg icon, avg window opens and there everything seems to be ok.

thanks for the help.

Why not give up the AVG and try MSE instead? It leaves a smaller footprint and runs silently in the background protecting your computer.
