Did you upgrade via the user interface? If yes:

I'd recommend a clean install of v9.0.2011.

1. Download Avastclear, Rejzors uninstall tool and the appropriate Avast program edition

http://files.avast.com/iavs9x/avast_free_antivirus_setup.exe
http://files.avast.com/iavs9x/avast_pro_antivirus_setup.exe
http://files.avast.com/iavs9x/avast_internet_security_setup.exe
http://files.avast.com/iavs9x/avast_premier_antivirus_setup.exe

Avastclear : http://files.avast.com/iavs9x/avastclear.exe
Rejzors Uninstall tool: http://rejzor.wordpress.com/avast-cleanup-tool/

2. Uninstall Avast by control panel  [If you don't have Avast in control Panel go to #4]
3. Uninstall in safe mode using Avastclear.
4. Run Rejzors Uninstall Utility in Normal Mode (removes traces avastclear doesn't) - reboot.
Check : Once uninstalled check in device manager>view>show hidden devices if there is anything related to avast with a yellow triangle.. if so, uninstall it and reboot.
5. Install the version you downloaded.
6. Reboot.

What was your previous anti-virus before Avast?

Run a quick scan with Malwarebytes to eliminate any chance of infection?

Which avast suite? (free, pro etc)?

The most common cause of this is something blocking avast, firewall, etc.

What is your operating system and firewall ?
Does it allow avastSvc.exe internet access ?
- If it does delete the entry for it and reconnect to the internet, this should force the firewall to ask permission again.

I have just installed windows 7 - 64 Bit and Avast is always my choice of anti virus so there is no chance of being infected? and its the standard free antivirus.

I read somewhere that the web shield might be being blocked by the firewall but when i went into my firewall then add a program to be allowed i couldnt find the web shield in the avast folder?

There is no web shield file as such, you are looking for the avastSvc.exe as I mentioned in my post.

You didn't say what is your firewall is ?

Windows Firewall and Avast don't have issues..

You never answered which program edition of Avast you are using (home, pro)...

I'd also run a Malwarebytes scan for the purpose of it..

Sorry, my mistake. I should have typed in "free". Once you've ran a scan, could you clarify the exact version of your avast? Program version.

I honestly am now clueless here... last thing to suggest.. an avast repair..

Control Panel>Program And Features>Uninstall a Program>Avast>Change>Repair and follow instructions... then reboot (important)
