how come google chrome isnt working?

[Meer]

this is most likely your antivirus program blocking Chrome from accessing the internet. The firewall is blocking Google Chrome because the antivirus program no longer recognizes it - even though it is on the list of permitted programs. To fix this problem, make sure your antivirus and/or firewall software are configured as a trusted application to allow Chrome to access the internet.

Note: The Chrome.exe file to add to allowed lists can be found here: User folder>App Data>Local>Google>Chrome>Application. (You have to have Hide Folders disabled to see the AppData and Local Settings folders).
