I had no problems with plugin more than 6 months, all mails with
virus were detected by AVG and quarantined in TB's Quarantine.

As I alredy told, there is a known, reported and confirmed bug in TB
with checking nested messages. I have tested it fully and problem
occurs in many cases, but not allways. When I receive message with
virus as an attachment, it was detected allways by AVG. When I
forwarded this message with virus as and MIME attachment, it was
possible to store it and send to user without warning. This is a
problem in TB, not in plugin, because it didn't received whole
message, only part of it. AVG developer confirmed this bug in TB.

Second bug in TB already specified in BugTraq is a problem with
partial messages. Original message can be splitted to smaller parts
and sent via Internet. This is useful, when has ISP set limit on SMTP
server and message can't be sent because of bigger size. When are all
parts of original message received, mailer (only OE and TB) join them
to one message. Problem is, that joined message is not checked for
viruses. I have reported this bug week ago and I hope, it will be
fixed in a new version of The Bat!
