I'm interested in how many use a Hosts File, and if so, what you're using. I notice many are using SpywareBlaster innoculation, as I do. The Comodo firewall/HIPS emphasizes white-listing as a basis for trusted apps, as does Online Armor. Online Armor includes a short Hosts File. I didn't check to see if Comodo also uses a resident Hosts file. Opinions seem to vary as to using a large comprehensive Hosts file or a smaller Hosts file with emphasis on the most-dangerous threats - or none at all. How many use a smaller Hosts file created solely from your own entries? I have the current large MVPS Hosts File resident, with a few additions and a few edits to allow site-loading (DrudgeReport, etc.). This is in addition to the black-lists of SuperAntiSpyware, SpywareBlaster, NOD32 and Online Armor native Hosts File and black list. The MVPS Hosts File goes well beyond adware to include known malware sites - but is it overkill? So, what are you using and what's your philosophy on this aspect of malware prevention?
