Hi , I have been experiencing a few glitches that lead me think I may have an unwelcome guest(s) , the helpers here have aided me twice before and as I am so grateful I dont want to waste anyones time. The latest glitches include freezing of mouse/keyboard - I changed all batteries reinstalled driver but still keeps happening , also done a restore to a time prior to this error - again no help - other glitches include the unwanted pop up of the calculator , flicking from windows without me clicking on said window.
anyway heres the log
Thank you
