I have to disable HTTPS scanning to work on my https pages. Well known https sites such as google and gmail don’t work in my browsers with HTTP scanning enabled in avast?? I have tried on chrome, firefox and internet explorer.
OS is Windows 7, service pack 1 and is updated. avast latest version although installed from a year and half.
Try a clean install…
Download and save http://files.avast.com/iavs9x/avastclear.exe (Uninstaller)
Download and save http://files.avast.com/iavs9x/avast_free_antivirus_setup.exe (Installer)
Run the uninstaller from above. When prompted to reboot into safe mode click “yes”. (Do this each version of avast you have.)
Reboot
Run the installer from above.
Reboot and register.
