jab kisi pc per aik antivirus ko remove kar k dosra install kar dia jaye to windows slow ho jati ya to dono ko aik sath use kar lia jaye ya phir sirf aik he install kia jaye
agr aik ko uninstall kar k dosray ko install karein gay
is ka aik hal hai k new windows install ki jaye aur windows 7/8/8.1/10 mein windows defender hota hai jo k builtin antivirus hai us ko manual update karein aur use karein kisi bhee third party ka antivirus use na karein
