I have tried most tools including having paid for spybot, spyhunter,adaware2007 etc to no avail..i have done deep virus scans   registry fixers et al..help!! 
The pop ups keep coming back despite my trying to poison there paths in the hosts file i restricted sites in blocked cookies etc..
any ideas  one of the scans comes back with  slagent and LAN CONFIG i remove them from the registry or destroy them using tools but they come back..it must be hiding somewhere.....
cheers
