Some time back I had dozens (if not 100's) of entries in my hosts file to block known malware/adware sites. It was awkward and required near constant updating. At some point (memory does not serve me) I said "screw it" and now have a default hosts file, no additional entries. I rely on Malwarebytes Pro and Panda A/V and they seem to work for me. What is your approach to a healthy hosts file?
