Does anyone know which antivirus program causes the least amount of slowdown while working in Microsoft Visual Studio? Every time my virus checker goes off I run into serious performance issues due to the system check. Does this happen to other people? Do you think the issue is the virus checker or could there be something wrong with my build? If it is virus checker induced, what software causes the least amount of system drain. If it's the build, any thoughts on how I can alleviate it?
