Solved: windows 8 mouse moving on its own

I have an issue on machine (friends , so not in front of it now)
where the mouse moves on its own

windows version 8
Sony vaio laptop

if you move the sound volume up - it immediately moves down

on the start screen - the tiles are immediately moved to the left , and you do not have time to click on the desktop icon before its moved off the screen

on google chrome , if you goto settings
>advanced settings
>clear bowser data
click on the drop down for 4weeks etc - it immediately returns to 4 weeks - so you cannot use the dropdown to select other options

I'm running
Avast scan
Malwarebytes and superantispyware

it has the conduit search

any recommendations ?
