I want to know if there's any chance making it in C#??
You have to know that you can do anything with any language, so technically, it is Yes.
But in fact your answer is No and this with any language you choose.
Because you ask this question tells us that you lack the needed expertize to do this project.
Making an antivirus software is a huge project and it can be conducted only by fully seasoned professional programmers with deep expertize in this domain. And making the antivirus is just an aspect of the problem, keeping it up to date, as new viruses comes, is a full project by itself.
An indication of the difficulty is to count how many product are available, a,d how many source codes are on GitHub.
