Description: 컴컴컴컴컴컴 Overwritting Virus Construction Toolkit is a virus source generator program designed for makeing overwritting virii. The program is using a external configuration file (specified as the 1st parameter) for creating a virus. With this program can be created only overwritting virii! Any other users who don't like makeing overwritting virii, can use Virus Costruction Toolkit (VCT) made by the same author which will be released very soon. OVCT wasn't made for creating tons of overwritting virii by lamers. The purpose of this program is to help beginner virus writers in better understanding the code. Every guy who wants to become a virus writter MUST make at least one overwritting virus. This is the beginning for everyone. The code made by OVCT is 100% working comented assembler code. The code has been tested with TASM 3.2 and TLINK 5.1 from Borland. (P.S. MASM sucks!!!) Author's notes: 컴컴컴컴컴컴컴� I made this program, because I don't agree with all those virus construction kits out there, who combine overwritting virii with non-overwritting. My opinion is that there must be separeted... There must be some good overwritting construction kits, AND there must be some good non-overwritting construction kits! That's why I made this shit and now I'm giving it to you... Another thing: most of the construction kits out there DON'T MAKE "GOOD" CODE! Many (not all of them) can't make clean ASM code... :-( The sources generated by them are all fucked up! Here's the problem! If we made these programs for beginners then we SHOULD make them generate good code (that means compile without errors)! For any of you guys who are wondering why didn't I made non-overwritting TSR virii: "TSR OVERWRITTING VIRII SUCKS!". Overwritting virii should be made only for learning purposes and not for distributing them out! A overwritting TSR virus CAN'T EXIST! IT SHOULDN'T EXIST! Imagine how fast you can destroy data with it! You can do it only if you're a BIG LAMER!!! I don't know if OVCT has any bugs. I've tested it on several computers and it's working! Still, if you find any bugs or you think that I can add/modify something to OVCT (maybe I'll release release a new version), please send them to my e-mail adress. Anyway, if this program helps somebody in learning how to make virii, please send me an e-mail too. I'd like to know that.
