This morning I told my mail client to check for new messages. I received "Buffer overrun detected, ... in ashmaisv.exe" and the program had to disable itself.
Avast! 4.1 Home Edition, Build 4.1.357
Client: Mozilla Thunderbird
OS: Win 2k
Nothing's new, nothings been changed.
I reboot the computer, Avast loaded, I loaded Thunderbird, and then told T-bird to get new messages. It showed over 100 messages in one account (normal business +spam magnet account) and various other counts in my other POP accounts. During download, buffer overran again. Some large group of messaqes were downloaded, will need to re-boot or somehow disable Avast to see what's remaining.
Strategy? I will remove Avast and re-install.
