This time: Sophos Anti-Virus. On internet update, this program downloads updated application files for all possible languages (and it speaks an awfull lot of languages). And no option to turn it off. So I happily downloaded the updates for swedish, italian, spanish, danish, french and some others, which any of them I haven't installed. It took 15 minutes on my parents ISDN connection - and they pay for every kilobyte. If Sophos is an average virus scanner (I don't know), I suppose this updates to happen every week or so: Horror!
At least, however, unlike many other anti virus applications, Sophos doesn't require a restart on update.
