Hi. is it normal for my avast to reset its shields. I’ve been online for about 3 hours and suddenly all the shields reset to 0/0 for no reason.
Try a repair. Control Panel>Uninstall a Program>double click “avast”>click “repair”>reboot. 
Hi. Just before the shield reset happened Avast went to the home tab and the smiley face box went yellow for brief second
Did you try a repair as I suggested? ???
Yes but I think your a little confused, Avast reset its self, the shields all went back to 0/0, then came back on a few seconds later, while I was surfing internet. Avast froze for a few seconds and the shields reset
What is your OS?
What other security software do you have now or “ever” had?
If uninstalled, how was it uninstalled?
Windows 8 and only security I have ever had is avast and Malawarebytes
What version of avast? ???
Windows 8 or Windows 8.1? ???
There are some known issues with Win 8.1
If you are using Win 8.1 see http://forum.avast.com/index.php?topic=85094.msg690352#msg690352
Hi, I left it a week or so but its just done it again all the shields just restart to 0/0 despite fact, i’ve been surfing internet for few hours
