Not a rumour!
The un-named app is real, although what threat is presents I do not know, I got a typical hysterical email telling me to check for this app before the sky falls in and I grow too many ears and unusually for me, thought I'd check it out.
Lo and behold, an un-named app does appear in my application list, I've now removed it but not sure how lethal it may or may not be.
