Undeletable Application Extension?

Question

i have a application extension called "C:\WINDOWS\system32\esent97o.dll" and it dosnt delete for some reason. Not even Avast can do anything about it. Can anyone help me?

Answer 1

Open up the dos prompt (you might need to run as an administrator, right click for options)

then type:

del C:\WINDOWS\system32\esent97o.dll /F

/F forces to delete read only files.

Note that the file will not be sent to the recycle bin, so use at your own risk.

Answer 2

Turn off your machine.

Keep tapping F8 button->In windows advance boot menu->Select safe mode.->Choose your user account.

There you can delete or rename the file esent97o.dll.
