Okay now ill remove avast.But 1 more query since system pool's already been corrupted will system fix it automatically or do i need to perform any manual method to fix it?

just uninstall avast?

Hi and welcome

these were probably caused by your avast AV file aswMonFlt.sys. corrupting memory;


I would uninstall it to see if the problem goes away and then re-install the AV of choice.
You also have 2 really old drivers


I would also run a system file check
type cmd in search>right click and run as admin>sfc /scannow

let us know the results

Ken

C:\>sfc /scannow

Beginning system scan.This process will take some time.

Beginning verification phase of system scan.Verification 100% complete.

Windows Resource Protection did not find any integrity violations.

What is secdrv.SYS related to? Since realtek driver is the only one that i had manually installed.What is secdrv.SYS ?
