So my laptop was recently attacked by malwares. I tried removing them using windows defender and I think they got removed. But afterwards I am suffering from following problems: 1. Windows apps like Groove music, default video player of windows, calculator etc. have all just disappeared...vanished...can't find them....can't run them. 2. Laptop stability now sucks.....Some services not running.... 3. Most importantly, whole taskbar is unclickable . I mean I can't "left click" anywhere on taskbar, though right click works. I have tried several things including power shell method but to no avail. Please help!! Thanks in advanced..
