I am using Avast! free version – it is updated to 6.0.1091 – on Windows 7 64.
(Seemingly) At random, Avast noted me that the shield wasn’t working. This was not upon an update. Fixing, Uninstall/Reinstall do not work. The button to “Fix it” and “Turn on” are enabled, as if I should be able to click them, but they do nothing. Note that only the Network Shield is not working.
When I try to turn them on I get a message dialog that assures me, “The following components could not be started: Network Shield.”
I am at the end of my list of ideas of what to do or what could be wrong. Any help?
I figured it out and if anyone else gets a similar problem, this is how it was fixed:
Left over registry keys from uninstalling Avast corrupted the fresh install. To avoid this, I used “Fix Issues” with CCleaner to clean my registry after uninstalling and before reinstalling. I don’t know what caused Avast to stop working in the first place, but if an uninstall is necessary, don’t forget to clean the registry! Everything is fine now.
I had this problem when I updated to Windows 8. Simply run the uninstall utility in Windows and “repair”. That fixed mine (in Windows 8 you right click on the Avast app and click uninstall. That will take you to the uninstall program section).
As the original OP was on Win7 then that would be a different problem to your win8 plus this topic is a year and a half old and Win 8 wasn’t even around then
