PC Security: Email Security and Spam

Email has really become an important part of our world, and our lives, over the past ten years. It is also a very common source of infection when it comes to computer viruses. These viruses usually arrive via email, inside attachments. Even though we have been repeatedly warned about not opening attachments from people that we don't know, many people still do.

While you may think that this does not affect you because you do not open such attachments, you would be wrong if you someone you know opens those attachments and has your email address inside their computer address book. If you are on a network, and such an infected attachment gets opened on another computer in that network, your computer will most likely be affected as well.

One way that Internet Service Providers (ISP) and Email Service Providers (ESP) are cutting down on the email virus problem is by implementing software to detect and move spam messages. Sometimes, however, the spam will get through the spam filter, and it is up to the user to use the 'this is spam' feature that comes with their email service.

It is important to understand exactly what spam is before you hit that 'this is spam' button, however. Spam is unsolicited e-mail. It is not email that you've requested to receive. For example, if you filled out a form to subscribe to an opt-in email list, the mail that you receive from that list is not spam, and reporting it as spam is not the way to unsubscribe.

You must remember that spam filtering isn't 100% accurate, and by submitting false spam reports, you will only be delaying the accuracy rate of the spam blocker, which means that you will continue to receive unsolicited email. However, in order to stop spam, when you receive spam, it is important to use the 'this is spam' button.

Because the antispam filter is not 100% accurate, it is also important to scan through the subject lines of the emails in your spam or junk folder on a regular basis. Authentication may play a major role in helping you to distinguish spam messages from non-spam messages. Authentication basically tells you who the sender of the email is, and it is used as a spam fingerprint check by the filters as well.

If you use a local email client, such as Microsoft Outlook, you should already have a free spam blocker installed with that software. If you use a different brand email client, check to be sure that there is indeed a spam blocker included, and if there isn't, be sure to look for one. Your email server may provide these free of charge as well.
