A small, experimental antivirus program written in Batch
Basically, it get the hash from a file and then compare it with a bunch of hashes inside the database. If it's in the database, then it'll be counted as a virus and get deleted.
There's some utilities too, but basically that's how JellyAV works.
Heck no!
First of all, this is not a serious project, this is an experimental project just to show how I created a crappy antivirus in Batch. Second of all, this antivirus only works will pre-existing hashes in the database, when encountering a new born malware, it'll not work at all. Furthermore, the database is not even that big, so you'll probably still be infected with old-ass viruses.
However, if you're a Batch developer or a crappy scripter like me, then you can try it out and build your own thing if you want :)
I took the database from here, be sure to check them out!
Ironically, you should turn off your already existing antivirus software as Batch files are marked as malicious, and run JellyAV as administrator for it to work properly.
