have been getting a popup box saying your computer is infected,with spyware click here to resolve etc. so have run a couple of different spyware programs and have found. spysheriff savenow newdotnet ad.yieldmanage pest trap
but the spyware programs wont remove them unless i buy. have only got spyware doctor 3 but it hasnt detected them so is there any free spyware that will get rid of them.or any other way, have tried ad+remove.
have also found out that the popup box is part of one of the spywares.
