To see if avast! is scanning emails, check one of these points:
Is the avast icon (the special one of email scanning) be shown in the system tray?
Is your email header with the lines X-Antivirus: avast! (VPS 0XXX-X, XX/XX/2005), Inbound message and X-Antivirus-Status: Clean? (Right click the message, choose Properties and Details)
Are clean notes added at the bottom of the email? (Internet Mail provider settings)
I ran the test on the link included, and Avast! and the ISP worked. In fact, the ISP was so thoroughly bombarded that it shut down the email account for a few hours.
A suggestion: wouldn’t it be easier to have the program list the active account(s) somewhere?
Maybe… other users won’t want to see this list… specially if they have some ‘hidden’ accounts.
Anyway, if you have XP all new accounts are protected automatically and transparently. If you have 9x or Milllenium, you could check the proper option to do the same, automatically.
I think there isn’t much problem 8)
