This is probably already known, but after installing lion with an existing Avast Mac Beta, lost all Web browsing capability and inbound mail
could still ping/send mail
disabling web-shield and mail shield re-enables access.
Hallo,
this is a known flaw and we’re working on a working workaround (the original cause is redirection functionality in Lion’s PF firewall which hasn’t been fixed by Apple yet - at least in this first Lion release it’s still broken - thus, our present beta just preventively disables network shields on 10.7).
regards,
pc
The latest beta update (avast-29138.dmg) solves the web/mail shield issue on Lion.
