Few days ago I was trying to download a software from a website and it gave me an installer. I usually don't run installer but I accidentally clicked it and it started hijacking browser and installed some adware etc. I cleaned them up one by one using task manager and deleted/uninstalled them . Restored the chrome and also used Malwarebytes to remove rest of them. But since then my computer starts very slowly and every start up program starts very late. I have my OS on SSD but it feels like something is starting up in the background and causing rest of the programs to lag, mouse pointer lags etc. When I go to safe mode every thing is normal. I have tried Malwarebytes, avg, avast and bit and cleared whatever they found(nothing interesting). But the problem is still there. I have lots of softwares and settings which can't be reinstalled from scratch. So please help.Also I tried DISM tool and sfc/scannow ...they failed to complete in normal mode but worked perfectly in safe mode. Problem is still here though.
