Overdue apologies and thanks to StaceyF for my 'dissing' the suggestion made - I thought, because I had sorted safeboot and Malwarebytes already it would not help.
Ran it this PM as per the link and I have now had a 'clean' Malwarebytes scan, and am running 'housecall' through the whole system at this time. No flagging of worm bagle so far. I do, however, still have the folder as above 'Documents and Settings\xxxxxx\Application Data\drivers\downld' which continually reappears on reboot (as a hidden but empty folder).
Other problem is system restore is still not working so I ain't out of the woods yet, but a bit closer to the edge
