Here is something that might help - create a file of the same type as whatever 851.7 file you see a lot of, i mean a lot a lot, and rename it to something like "[file name] 851.7 is a virus - DELETE" then share it. If it's .mp3's then do an .mp3 if its a .zip then do a .zip, etc.

It should show up on the same search page, and people will start to get the message and some will even catch on that all those 851.7 files are also virii.
