Windows 10 Installation Failure

Since updating to windows 10 I've had alot of trouble with my AVG installation, so I uninstalled it and now I get this error message whenever I try to re-install. I need some help, I doubt the windows 10 built in defender will be effective for very long if at all.

Incase the picture does appear below it said:
"Waitng for watchdog service start failed"
"Severity: Error"
"Error code: 0xC0070643"
"Error message: General internal error."
"Additional message: MSI Engine: Failed to install the product."
"@AVGMSI_Error27007"
"Waiting for watchdog service start failed (0xC0070426)" "Context: AVG product installation, MSI action failed"
The error message

That still isn't working, using the uninstalling tool did uninstall it but it AVG still won't install, it freezes at "Configuring Product" and is giving the same error. Can a non automated responce please check what this errorcode means?

Hello Pat. Sorry to heat about the inconvenience caused. Do you have any third party anti virus software installed on your computer? If so, please uninstall it completely. Please also have a look at http://avgclick.me/1Jm576W . Thank you.
