well, this is what TBAV says on all djgpp2 programs:
 Heuristic flags: c!?ZK AT i
 c  No checksum / recovery information (Anti-Vir.Dat) available. 
 !  Invalid opcode (non-8088 instructions) or out-of-range branch. 
 ?  Inconsistent exe-header.  Might be a virus but can also be a bug. 
 Z  EXE/COM determination.  The program tries to check whether a file
    is a COM or EXE file.  Viruses need to do this to infect a program. 
 K  Unusual stack.  The program has a suspicious stack or an odd stack. 
 @  Encountered instructions which are not likely to be generated by
    an assembler, but by some code generator like a polymorphic virus. 
 i  Additional data found at end of file. Probably internal overlay.
