I opened Add/Remove software and discovered Bullseye had added itself to my system. Research showed it to be a very aggressive data miner. The trouble came when trying to delete it. Adaware didn't touch it and its own Remove 'thingy' wouldn't work without answering questionaire on advertising none of which could be answered in the negative. I tried deleting it in Windows Explorer - no good. I changed my browser to Firefox as my only recourse. Anyone experienced this nasty piece of kit and ny advice on delting it?
If it's in Add or Remove programs it is almost certainly in System Restore. Turn Sytem Restore Off and scan with one of the above suggestions or I have found this click here very good when others fail. If turning off system restore doesn't solve it try again the same way but in Safe Mode (Tap F8 when booting)
