My homepage does start, but other sites are impossible to access.
But this answer from Techie 101 in the thread of Bert Turner: "Must disable Avast to browse.. Oh man." explains enough to me
I'm confident waiting for the next update, until then I disable Webshield service.
Techie101: My goodness! Web Shield has caused a rain of terror upon us!
Ok, general information. The Web Shield is activated upon boot by default. If you turn it off, using the TERMINATE button, it will not enable by a merely starting the OAP module. You will need to go into the WS module and use the Continue command.
The Web Shield for some reason unclear right now "filters" too good! Some sites appear to it as "suspicious or dangerous" and it will not let them pass. This can be remedied by adding them to the Exceptions list within The WS module under Customize, or try disabling the "Intelligent Stream scanning" function under the Basic tab.
Zone Alarm has a separate problem because it interacts with Port 80. Search the forum for the solution.
You do not need to disable the entire Avast Resident Scanner if you are having surfing difficulty.
Just disable the Web Shield until the issue/s can be resolved.
Why remove ALL protection when only a small "limitation" is necessary.
The Web Shield is an excellent new feature but with all new things comes some "bugs" which everyone here and the Avast Team are working to resolve (as always. )
Good luck.
