so take for example i accidentally downloaded something like an application executable or a pdf or anything for that matter that had something malicious in it and my antivirus either didn't pick it up or deleted it as a false positive, in either situation how would i be able to tell if the file was actually infected? which language should i learn for these types of things? i will only be operating on windows platforms.
edit- if i need to know more than a language then kindly state what i would need to learn to actively perform an analysis of any virus to figure out what it is, where it came from, what it stole and what it's after?
