I've found only one AV so far that this archive can't bring down, and thats that little Polish gem I found last night. They seem to use a pretty simple method to eliminate this type of problem - or at least control it.
Sorry to disappoint you, guys, but BitDefender has no problem whatsoever with this zip-file. It doesn't even consider it a virus, but an Eicar testfile. Time to scan it was almost instant. This was done on my PC for work. Avast Pro is installed on my personal PC. ;)
