It is mainly for virus scanning (in AIS for antispam too, but its always called "avast! addin") when you have SSL connection not listed in avast mailshield or you are using exchange account.
Hi Petr,
After disabling avast add in, i still get my emails scanned which is fine. Then what is the use of the add in? And i still don't understand why i get the error if i enable it.
