Pharming is a scamming practice in which malicious code is installed on a personal computer or server, misdirecting users to(71)fraudulent Web sites without their knowledge or consent. Pharming has been called "phishing without a lure".

But in pharming, larger numbers of computer users can be(73)victimized because it is not necessary to target individuals one by one and no conscious action is required on the part of the victim.

A computer with a compromised host file will go to the fake Web site even if a user types in the correct Internet address or clicks on an affected(74)bookmark entry. Some spyware removal programs can correct the corruption, but it frequently recurs unless the user changes browsing.(75)habits.
