Time consuming and annoying, spam is a real nuisance of Internet usage. Unwanted mail often contains malware such as viruses and spyware that infect computers, steal personal data and cause lots of troubles to the PC user. Spam blockers and filters are the solution to the problem and although they may not eliminate unwanted emails 100%, you will still get rid of about 90%. And since we don’t feel comfortable paying for very expensive tools, the average user normally relies on free spam blockers downloaded from the Internet. You can select integrated, standalone and online tools to assist you with the filtering and blockage of spam.

Integrated software is the most popular model of free spam blockers. After the installation on the computer this kind of software programs add new settings to the email application so that messages can be marked as spam or not spam. This category includes a very large number of free spam blockers, and the user only needs to make a choice on the basis of reviews and according to computer specificity. There are cases with so-called spam blockers that instead of protecting the computer, behave like malware, changing settings and exposing the PC to external invasion.

The free spam blockers should be compatible with the computer operating platform and the email provider. There are softwares designed to operate with Outlook and Outlook Express only and they will not be suitable for Yahoo, Gmail or other email services. An alternative to an integrated program is the standalone anti-spam tool that enables the message previewing on the server before allowing the mail download into your computer. Some of the paid or free spam blockers in this category have the disadvantage of being operational only if you open the program before accessing the mail. Test the program before installing it so as to make sure that the filtering and blocking of spam is automatic.

As for online freeware spam blockers, corporations are the first to choose server programs that perform the unwanted mail blockage tasks. Anti-spam programs conducted online sent the unwanted messages in the junk mail without the interference of the PC operator. Online spam blockers or anti-spam server softwares are hard to get for free, as most of them are charged on a monthly basis.
