generally windows defender is useless, self compiled programs are scanned and killed
programs i have compiled myself
7z.exe and reduced version
zstd
packjpg
lz77 custom version
lzham
maybe more
most of them are found inside my compression pack
so no wonder that is doent work :/
small bug fix, extract this to the v2 folder and replace precomp.exe
edit update 1 moved to main post
