When I import hpHosts and MVPS HOSTS file and I ask for duplicate deletion somehow I get two entries for some of them.
I think its because that hpHosts has no comments whereas MVPS entries sometimes have comments.
e.g.
SMART-SECURITY.BIZ
Shouldn't it only compare on the domain and not the whole entry?
If you're referring to items like smart-security.biz and www.smart-security.biz, then these are not duplicates because blocking one won't prevent you from visiting the other.
