I have a problem in that I regularly picked up a tracker called Red Sheriff.
I am almost certain that this affected my screen/mouse moving the image when I attempted to click a link, as the removal of Red Sheriff solved the problem each time.
I have run the latest version of Adaware and it has not picked up a copy Red Sheriff yet. My surfing habits are unchanged and the problem persists each run. i do not believe that the site that was using Red Sheriff has decided to use it no longer at the same time as the update.
Having said that, the new update is much more selective in the files it scans, so is very much faster.
