> Try to detect a fake server, sending bogus search results

since some days I noticed on nearly every search I get one single fake search result (obviously a dangerous executable) with a very high number of sources so it's always on first position on the search results. The filename is always built of my search term and "_ShareAccelerator.exe", i.e. if I do a global search on "schafkopf" (a german cards game, there are several freeware versions floating around) I get "schafkopf_Shareaccelerator.exe" with about 6500 full sources. There must be at least one bogus server that builds this filename from my search term.

Of course I use a big and weekly updated ipfilter.dat! And I use a self compiled version of current CVS with an self made addition to prevent adding any servers which are located in the United States according to ip2country. So I have no US servers in my list.

To investigate which server it is I tried to find the location in source where the server results are added to the list. I wanted to write a debug line with the server's ip to the debug log to find out which server it is as a first step.

Can someone point me to the proper file and function in source where both server ip and filename from global search results are available?

What if the user does a global search without specifying any additional parameters except the keywords? unsure.gif I do that sometimes when I'm not sure of the size or extension.

Eg. If I'm searching for a movie and its subtitles. I get the big movie (avi, mkv, mp4, iso, rar, whatever) and the small subtitles (srt, rar zip, sub, idx, whatever).
