Quarantining Spam
Antispam filters automatically quarantine the spam emails, ensuring your inbox is spam free. Such quarantined emails are held for a fixed number of days, say 30 days or so, and then dumped. During that period, you can check and recover any legitimate email that may have been quarantined.
Automatic Filter Updates
Most of the anti-virus software comes with automatic filter update feature for timely detection of new types of Malware threats. Automatic updates not only helps the anti-spam software to stay up-to-date, it also helps secure your system from new kinds of Malware.
Monitoring Multiple Accounts

Your Personal Whitelist
Some anti-spam software allows you to maintain a ‘friendly’ list of people whose emails you wish to accept. These emails will never be mistaken for spam as against the blacklist of spammers. You can also update the list in the future.
Reporting Spam
Some anti-spam programs allow you to report spam back to the company supplying the program. It helps that company to develop new type of filters based on the analysis of the reported spam.
Emails have become a very popular way of advertising, and it is time that you start filtering your emails, to avoid spam. Most of the anti-spam solutions are signature based that use their signature file (blacklist) to detect and respond to new type of Malware.
In signature based anti-spam software, new and unknown types of Malware goes undetected since there is a time gap between the time these new type of Malware threats are released and the time anti-spam software vendors have identified them and updated their signature file. This is where Containment technology comes into play.
Containment technology works by keeping the threats or harmful files under control or within certain limits. The harmful files are processed in a restricted operating system environment, thus controlling the resources and the spread of infection.
