Hey, I’ve just upgraded to avast Internet Security but do not have the Firewall or Network Lock buttons on the user interface screen. Be grateful for any ideas to fix this. Thanks.
how did you upgrade ? just put the licens in avast free ?
you probably need to uninstall and download the ais.exe and install again
Yes I think you must be right! I didn’t fully read the download info and must have skipped something. Anyway, I uninstalled, reinstalled and all is working fin now. Thanks for your reply.
good news.
