Arj compression – anyone remember this?

We had an interesting ticket come in today where an antispam system had let through a file compressed with the arj format. This immediately brought back memories of compressing files back at university – in the very early 90’s and a format that used to be very popular but nowadays most people, including the rest of our techs had never even heard of.
I am guessing the spammers were hoping that their recipients have winzip, winrar or 7zip installed so they will be able to open the infected file and that as the file format is so old, av scanners will not check them.

Anyone else out there remember Arj files and anyone (dare to admit that they) still use it?
