Did You Know: Spam Filtering & Virus Protection Go Hand-in-Hand

You may already be aware that spam filtering can save you from having to deal with countless emails, but did you know that it can also help you with virus protection?

Spam can be far worse than annoying promotional emails you never asked for. It’s also one of the main paths of entry that hackers use to launch cyberattacks.

Hackers are constantly looking for ways to get to you. Often, it’s when you are browsing, but your email inbox provides another great opportunity that they can’t pass up.

So what do they do? Hackers send thousands or millions of messages out to unsuspecting email users, in the hopes that they make it in front of the users’ eyes. When someone opens one of these emails, they may be met with a phishing attack that attempts to manipulate them into handing over their password or other sensitive details.

Alternatively, the message may include an attachment or a link to malware, alongside a crafty trick that makes the user execute it on their computer.

Thankfully, spam filtering can help to put a stop to these and other attacks.


Spam filtering doesn’t just save you from having to deal with a constant flow of irritating messages. It also helps to stop you from ever seeing these attacks. Since a good spam filter will block many of these phishing attempts and malware-laden emails, it makes it impossible for you to fall for them.

You can’t be tricked by something that never makes it into your inbox.

A well-tuned spam filter will allow in your critical emails, while keeping out most of the spam, helping to provide virus protection.

A properly set up spam filter can even prevent attackers from making it seem like you are spamming yourself. This may seem confusing, but in general, email systems aren’t the best at validating the sender of an email. In certain circumstances, hackers can take advantage of this and use it to bypass your spam filter.

They can get through by making the email appear as though it’s coming from your own address. Let’s say your address is You may suddenly find emails from appearing in your inbox. Emails that you know you didn’t send.

These are really just spam messages. Hackers take advantage of this quirk of the email system, and use it to try to get their messages through to your inbox, so that they can then launch phishing attacks, try to make you download malware, or set up other attacks.
