Hi this is Sai Dheeraj
My laptop HP15S Du0122tu
I am been using this laptop for the past 4 years there were no issues but my brother turned off windows defender for some stupid games, and my fully working laptop started showing side effects, I reset the whole notebook installed Windows again purchased the version, and added quick heal it removed 2 viruses but still my keyboard is not working, I am just smashed my head into the wall then I tried every situation to fix this from YouTube, Microsoft, HP, and other site but it didn't work, tho it works for maximum 1 hour and then my keyboard keys stopped working, these are
QWER UIOP and up arrow and left arrow
In the future I every key should stop working
