Adware Removal Guide : Spigot

CNET Safari extensionsSpigot is an adware company responsible for a
number of different adware programs. Recently, CNETšs Download.com site
has been brazenly wrapping a lot of Mac software in a CNET Installer
that also installs Spigotšs adware. (See Boycott CNETšs Download.com.)
Although this behavior on CNETšs part is despicable, and seems likely
to get them sued by multiple parties, the installer does inform the
user (if he/she actually reads the terms) of what will be done. I doubt
that Spigotšs adware will ever be detected as malware by anti-virus
software based only on this incident.

Slick Savings, Amazon Shopping Assistant, Ebay Shopping Assistant and
Domain Error Assistant. (See Identifications > Examine Browser

Not all of these may be present in all browsers.
Move the following items to the trash. Note that, if you donšt know how
to locate a file or folder based on the paths that I will give in the
instructions, you should read Locating files from paths.

in your browseršs preferences.
