I am trying to repair a laptop for an elderly neighbor it is a HP Pavilion dv5. It had several pups I removed with Malwarebytes,adwarecleaner and JRT. the computer seems to run fine now but when I attempt an update it fails and gives me error code 80070490 I have tried sfc it found corrupt file but was unable to repair them. i ran KB947821 fix from microsoft but it did not help. I also ran the fixit tool from microsoft but it also did not help. every time i start the computer after a while say 5 minutes a yellow shield shows up on the shutdown button but the on the menu that has restart and shutdown in it there is no shield. When I hit the shutdown button the computer attemps to install an update. I do not have a system disk, the computer does not come with one it has a rescue partition. I have looked on the internet and this seems to be a common problem from vista days i hope there is an easy fix I am missing. Help please.
