Ok!  I didn't expect what I am about to describe but with the last hour or so I subscribed to"Skype" for freebie service.
I've copied and pasted from broll this snippet -
5 Then:    
 m n x y 
 2 48 7 5 
 3 1680 41 29
The last line above reads as "Aussie flag icon" heading a DD_Menu (alt text suggests 'Skype actions'), and then is the Ph No. 3 1680 41 29.  The line terminates with a green phone button. Again there is alt text and allows me to call that Australian number (which I very much doubt exists).

Broll there is policy, not written but reasonably well understood, that all problems go through the queue! 

Seriously,  when I first saw this I was taken aback, I can't recount  my immediate thoughts but none related to Virus.

As I expected, the oddity does not occur on my other computer.  I do expect the line mentioned above to be similarly treated when I close this. 

I was not disappointed, in fact where I mentioned "Ph No.  " I got the same.
