Spam Filter Software Free

What is spam filter?

Margaret Rouse states that a spam filter is a program that is used to detect unsolicited and unwanted email and prevent those messages from getting to a user's inbox. Similar to some filtering programs, a spam filter looks for certain criteria on which it bases judgments, for example, the simplest and earliest versions (such as the one available with Microsoft's Hotmail) can be set to watch for particular words in the subject line of messages and to exclude these from the user's inbox. She adds that this method is not especially effective, too often omitting perfectly legitimate messages (these are called false positives) and letting actual spam through. More sophisticated programs, such as Bayesian filters or other heuristic filters, attempt to identify spam through suspicious word patterns or word frequency. Spam is any kind of email that you don’t want and that you didn’t sign up to receive. Some spam is annoying but harmless, but some might be part of an identity theft scam or other kind of fraud. You can get spam in instant messages, text messages, and on your social networking sites. This article primarily covers how to reduce spam email (http://www.microsoft.com/).
