Security Incidents: Re: Unknown Hosts file

Re: Unknown Hosts file

Setting hosts to bogus/erroneous address is one way that anti add/popup
work. Some of these, when installed, also install a integration plugin to
allow a user to select an add and instruct the program to effectively
"blackhole" the given website. Does that user have such a program
installed ? (as a side note, most of those will leave their "custom host
file" in there, even after uninstall...)
