I see, so basically, any real modification of the file beyond say the character length, would invalidate it?
Anyway, so far, only Norman AV was able to pick up every possible way I changed the file within reasonable limitations.. I even changed it some funny variations:
SACKO-NUTZSACK-ANTINUTZ-TEST-FILE and other variations, and Normal *STILL* picked it up. Then I turned off norman, and used every possible WIERD extension and naming definition I could think of, things like "MADONNA).ABC and other crap, and it still picked those up immediately upon entry to the directory.
Honestly, I don't have Avast installed on this PC so I cannot check how it would handle those yet. But I don't think 'Standing' in place of 'Standard' shouldn't me missed, should it? I don't know much about the inner workings of AV softwares (yet), but it seems to me changing a few letters shouldn't negate the detection? Heuristics?
