When compiling, "Incorrect function" error

Question

I'm trying to build a VS 2010 web project and I'm getting this error:

Could not write to output file 'C:\Users\me\myProject\obj\Debug\myProject.dll' -- 'Incorrect function.'

I've tried everything from reinstalling to editing folder permissions to running visual studio as system to moving it to a different folder and nothing resolves this error. Has anyone seen it before, or know what to do about it?

Sometimes antivirus software "decides" that the .dll or .exe that we are building is malware. Many such apps also have some sort of a white-list of files for which you can tell the antivirus to ignore them.
