I download my Home Edition (and registered it) 12th dec, so it's the newest one. The program works OK, it's the "Modify" part of the "Add/Remove" that don't work. You're supposed to be able to install and uninstall parts of avast! here right (if you would remove something you added at first install, or add a part that you didn't select at first install).
But when I do this it only works for a while. Then I get a message about a new version, it's automaticly downloaded, and then all modules I originally installed are back (even if I have used "Modify" to uninstall those.
BTW: Use Win98se
Note: I use Agent as a mail-program. And received viruses in mail always is saved to disk (temporary) before they are opened. Viruses with their own SMTP server is not stopped ny avast! anyway (but I guess ZoneAlarm will stop them). I don't then really see the need for using the mail-scanner?
