Thanxx for the link. These are not in Hosts format.
I am trying to use Comodo Internet Security Web Filter. Lists in Hosts format can be used in CIS. Dont know how to use lists that are not in Hosts format or is possible or not with CIS?
I tried hpHosts. Everything was fine but removing the lists takes very long time i.e more than 30 mins. Tried 3 times with the same results. Guess coz the lists is huge.
