On the "Select email account" only appears Outlook Express accounts and on the next screen I can choose wich pop or smtp account I wanna use, but i can choose only one... Should I run the wizard two times selecting one diferente pop account each time?
No, do not mess the 'default' email account (used to send files to Alwil Software for analisys, for instance) and the other Outlook Express accounts.
You can choose other email clients either...
Do I have to do this in every user ??
No, in Outlook Express part of the Mail Protection Wizard should be shown 'all' email accounts (in Windows 98). In Windows XP, as I have only one user, I'm not sure, maybe you can test.
I chance my avast4.ini file to work with opera, should i back to the default ??
Can you post that part of avast4.ini file (remove personal data, please).
