If any company came up with a complete anti spy ad ware solution it would be catastrophic, these firms feed off each other, analogy - Ford patent a car that runs on fresh air, great for Ford but everyone else goes bust, then Ford open garages that sell fresh air....pointless.
There is no solution and never in the near future will there be a solution to spy ad or any other ware installing on your com, cos if they want in they WILL get in no matter what current version you are running.
Dont want to be a wet blanket but market forces and all that.
