Hey john,
That's why I simplified the process: I blocked all .zip stuff ;)

NOTE! Most if not all AV software will not be able to detect and catch an
encrypted zip such as Bagle.J. The reason is this virus is sending (not in
all cases) the virus in encrypted zips using random CRC values, random file
names, and a list of extensions. The biggest problem is the random CRC
values.
