Recently I keep finding that the error log of my website has filled up with 
"file not found" errors, as people (or bots?) trawl my every subdirectory 
looking for a favicon (.ico or .gif) file in that subdirectory. I have one 
in the root directory which has always worked OK.

Is this evidence of attempted hacking, or has a standard been changed 
somewhere?
