# netassist.pl
# Plugin to determine if a system is infected with the BHO "My.Freeze.com".
# This is a BHO specifically for firefox and is installed as an addon using a
# third party installer. This is usually done when a user installs a product
# and is installed without the user reading all the information on the install.
# It usually requires the user to uncheck a box but as most users do not read
# everything it is installed unknowingly.
# If you look under the "addons" in firefox you will see an addon called
# "Freeze.com Net Assistant for Firefox", but you can only enable or disable
# it from there. To uninstall it completely from #the system you must
# uninstall from the system "add/remove" program under the control panel.
