It's possible to scan for it by using known parts of the file. The .ZIP is
not encrypted, the members are.

[root@coredump:/root] unzip Message.zip
Archive:  Message.zip
[Message.zip] frbdm.scr password:
   skipping: frbdm.scr               incorrect password
[root@coredump:/root] uvscan Message.zip
/root/Message.zip
        Found the W32/Bagle.gen!pwdzip (ED) virus !!!
[root@coredump:/root]


NOTE: I had to use the extra.dat from mcafee for this, the latest dat was not enough.

(Lets not getinto a "don't use root" war here ok?)
