Avast icon stays grey??

Hi every one. I just installed avast and i noticed that it said that the icon should change to blue then you are protected. It says if it is gray, it is still waiting for something. Well I did every thing i should but the icon stays gray. Please help me. What shall I do?

Have you tried:

Right click on avast tray icon
Start avast antivirus

Most probably it’s not a problem from avast but your video card and drivers…
If the providers are running you’re protected.
Does the ‘a’ icon have a red cross in it? If not, you’re ok.
