After spending a few hours trying to get rid of a very vicious spyware attack (searchmiracle) and trying many different programs to get rid of it ie: Ad-aware SE 1.05, Spybot 1.2, SpySubtract, CWShredder and many others the only one which worked was 'Spyware Doctor'! You can download the Spyware Doctor trial version but to be able to rid your system of the spyware you need to register it! Which I must say was quite a risk I took in registering, as I wasnt even sure it would do it seeing as all the others didnt, but alas it did work! Brilliant little program I must say.
All I can say on the matter is the SP2 add blocker is not worth a pinch of S***!! I will be going back to using the old faithfull 'PopUpKiller'!
Just thought I would let you all know about it.
