The Gator E-Wallet was one of the earlier and better known forms of spyware and/or adware. The program was described as your helpful online companion, that remembers your online logins and passwords. Unfortunately, the E-Wallet program installs GAIN, which is known to show pop-up ads and hijack Internet search results. It also returns visited websites to Claria Corporation's servers, so the program can analyze one's habits and thus display ads based on those habits.
