Firefox, Chrome, Avast all crash and won't restart

As it says above…after I had a FF crash, I restarted the computer (running Vista home) and neither FF nor Chrome browsers will start up at all. Avast (home edition) also wouldn’t start. I’ve uninstalled Avast and Chrome; reinstalled FF twice. No luck. Anyone else encounter this?

well i´ve had a lot of Chrome crashes and avast! is still working

I downloaded the Home edition today. After downloading, I could not access the internet through either IE-7 or Firefox. I eventually solved the problem by “terminating” the Web Shield provider. The other six providers remain active. My concern is that by having to terminate the Web Shield provider, I am not getting any protection when I’m surfing the web.

do you use personal firewall? Have you configured it to allow Webshield’s process (ashwebsv.exe) to connect to the Internet ?

Lukor, I tried your suggestion since I had incorrectly applied DavidR’s advice previously. This time I removed the ashServ.exe program from ZoneAlarm. Then I activated the Web Shield and successfully accessed the internet. Interestingly, ZA did NOT prompt me for permission, but since I don’t care if it does allow the service, I’m happy.

Thanks again for your help.
