I have been using Avast for several years - without any issues. Recently I was updated to the ver. 4.5X and things have not been the same since.
I am unable to send e-mail. I have tried everything suggested in these boards, but nothing has worked. I uninstalled 4.5 and reinstalled an earlier version. E-mail worked once again.
This is my config: WinXP SP2, OE and Thunderbird, ZoneAlarmPro, my ISP (wireless) does not use a sercure connection.
I downloaded AVG, installed it and the e-mail works fine. So, I decided to use AVG until the Avast e-mail issue is resolved.
P. S. My ISP tells me that this kind of issue in not unusual with some anti-virus programs. Norton and McAfee have caused the same issue with e-mail sending. The fix for Norton was to uninstall and reinstall. I tried this with Avast, but no luck - still not able to send email.
Any help would be appreciated.
