4 Ways in Which Malware Can Affect Your Network

Malware can have a serious impact on your business's computer network. Not only can it result in your office being unable to operate, but it could also result in confidential information being lost. The recent Wannacry malware attack crippled over 400,000 computers by locking users out. The only way to regain entry was to send money in the form of cryptocurrency to the attackers. As the old saying goes, prevention is better than cure, and this is certainly true when it comes to malware. Below is a guide to the various ways in which malware can infect a computer network.

Pop up ads

Some websites contain pop up ads. While these can be annoying, they may also contain malware. When an employee clicks to close a pop-up ad, they may, in fact, be authorising the installation of malware. The best way to avoid this is to install an ad-blocker on each machine. The ad blocker will help to prevent malicious ads from being displayed.


Email is a very popular way of spreading malware. Attackers will normally try to gain access to a person's email account. They will then send emails from this person which have an attachment. Because the email appears to come from a friendly account, many people will open the attachment without thinking about it. As the attachment opens, it installs malware onto the computer. To prevent this, you should install an anti-malware program on each computer which will scan attachments before they are opened.

Fake updates

Some attackers will create malware programs which masquerade as legitimate updates from software companies. If you receive a pop-up message asking if you want to install an update, you should not click yes. Instead, you should visit the software companies website and search for the update yourself.

USB sticks

If your staff use USB sticks, you should instruct them only to use them on company computers and not to plug them into any home electronics. Some malware is designed to be self-replicating. Once the malware has installed itself onto a machine, it will seek out portable drives which it can use to make a copy of itself. Once the USB stick is inserted into another computer, the malware will install itself and spread throughout the system. You should also warn staff that they should not connect personal USBs or hard drives to the company computer network.

If you would like to find out more about protecting your network, you should contact a computer service company that can help.
