Neat bit of lateral thinking.

A challenge Kan?  Yes, even in DOS/W9x this is relatively easy 
with the right tools. How about with my favourite W9x parsing utility 
LMOD.

cd "C:\PROGRAM FILES\GRISOFT\AVG6\UPDATE\"
echo @echo off > delbin.bat
dir *.BIN /a-d/o-d/b|lmod /L2-* del [] >> delbin.bat
delbin.bat

IIRC there's some DOS/W9x utilities that don't even need the 
intermediate batch file and can execute the DEL command directly 
which would reduce the above to 2 lines. Of course I'd personally use 
a single line xxcopy command for this with the /DB#30 approach and 
just leave a few extra .bin files behind until they 'aged'.
