I STIL FIND IT happy to see there are lot of AV out there that cant scan such file properly to detect virus.
The problem must be located in the unzip engine:
We've created a mixed ZIP now:
# unzip -l mixed-eicar.zip
Archive: mixed-eicar.zip

BTW: note here that "unzip" displays the escape sequences very proper!

Some AV software detect the virus only in second part of the ZIP file, so it looks like the first one is really skipped and not analysed.
