Hi,
The desktop takes about 30-40 seconds. I's an old machine though..
The laptop takes about 15-20 seconds. There were times today where the Avast icon came on without a warning, like it was enabled quickly.
I don't understand why both have suddenly been giving warnings that windows firewall is disabled.
On the laptop while it was infected malware came up with Registry Data Items Infected:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\FirewallDisableNotify (Disabled.SecurityCenter) -> Bad: (1) Good: (0) -> Quarantined and deleted successfully.
Thanks again for your help.
