If you believe you have been infected with some sort of adware or spyware, there are several ways to identify the culprit. It is usually easier to identify adware, because it is less harmful than spyware, and may come from legitimate companies.

The Google Toolbar has been accused of being spyware, because it includes a Page Rank feature, that tells Google where people are surfing on the Web. Ironically, the Google Toolbar offers pop-up blocking, preventing unwanted ads. The Page Rank feature on the Google Toolbar can be disabled, if you prefer not to send any information.

Most browser toolbars, like the Google Toolbar and the eBay Toolbar, are technically spyware, but they are also useful for many users.

Instant Messaging adware:
There is an application called “Buddylinks”, that sends commercial messages via AOL’s Instant Messenger (AIM). The messages appear to be a recommendation from an AIM user, encouraging contacts to visit a Web page to download a video game. This way, the program propagates, sending recommendations disguised as a contact. The company argues that the user accepts these messages explicitly, clicking in “agree” when installing the program.

Research Before You Download:
Spyware often is included with freeware and shareware, so it is advisable to research about programs before you install them. A simple search in Google, or checking sites dedicated to spyware can alert you about any problems people have reported with software.

Sites to research Spyware:
There are several databases online tracking spyware and adware, providing information about the possible impact they can have in his computer.
