Because i thought it would be the best way to start over, i uninstalled the free version.
I installed the latest 4.6 pro, pasted the serial in the program like it asked me to, and didn't get any notice whatsoever of malfunction. in my humble opinion, the program was working fine.
The first time i followed a link to the web i encountred the problems that i discribed in the first message, no connection to the web & no connection to my e-mail server possible.
I checked my firewall, and because the windows firewall didn't work like it used to do, i re-installed SP-2, and the firewall was reset in the original manner, i gave the firewall the necessary items it needs to give Avast permission to work.
And here we are, unless i disable the two shields (web & post) it seems impossible to get any outgoing traffic, the only traffic that's alowed, is Avast's own update, so, thats all i can tell about my conflict.
If i had an unofficial Avast, i wouldnt care and look for an other program, but i payed for it, so i hope to find a sollution for my troubles...
