Anti-Virus Program

[nsutton]

I have a few things I want to make that I havent yet so this will be a later project but I was just wondering,

How would a anti virus program work in C#?

I've seen ones on youtube that iterate through your HD and looks for keywords like "Virus","Trojan" and thats basically useless..

So how should a antivirus program detect if its a malicious file?

Thanks!

First of all I recommend you not to use C#.
try C++.

But why? He didn't explain the benefits of C++. Does the api only work on C++?

Why would a lower level language help?

C# is considered slower than C++. This discussion will help you consider what you want to do.
