This is classic ObAV Anti-virus source code, made with classic VB6, x86 ASM, and C.
This is an antivirus created by ojixzzz as founder and adierebel as co-founder. This software was created when the founder was 16 years old, and the co-founder was 13 years old.
Ten years later, one of them started a conversation. "Hey, ten years ago we did an anti-virus, and I still have the source code."
And the others answered. "So why do we publish it on Github and archive it?"
This is a hobby project, so you will notice that the source code is less organized.
