Solved Possible Virus or malware infection

Log as requested...
Many thanks for your assistance.
I am aboout to go out for a few hours so I will clean up with OTL as suggested first.On my return I will cary out the rest of your suggested steps.
Just a quick questionif I may. Prior to us doing anything the pc used to pop up a box asking me what I wanted to do with a cd or dvd placed in the drive. Similiarly , when I attached a usb Drive ( I think this is called autoplay?). Can I fix that once all other things are caried out?
All processes killed
