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?

They are simplifying the heuristics: if it's not on MS store, then it's a virus.
