These days, Windows Defender has a habit of declaring almost any executable a virus. I can compile a simple 'hello world' C++ code using the Microsoft C++ compiler and the resulting executable is immediately quarantined by Windows Defender as a virus. These numerous false positives begs the question, why is Windows Defender so bad at identifying a virus? Windows Defender appears to be so bad at identifying a virus threat it seems almost worthless? With so many false positives, what happened to Windows Defender to make it so bad at detecting an actual virus?
