Protecting your business from Malware – Small Business Cyber Security Guide

Although computer viruses have been around since Elk back in 1982, it is only in the last few decades that the words surrounding this aspect of our everyday lives have become the “norm”.

Terms like Malware and Spyware are now commonplace, but do you understand how best to protect your important business data from these types of automated attacks?

Tip 1: Always have up-to-date Anti Virus

Antivirus software – often included for free within popular operating systems – should be used on all computers and laptops.


Tip 2: Prevent downloads on your network

Software and programmes should only be installed if they are business critical.

Staff accounts should only have enough access required to perform their role, with extra permissions (i.e. for administrators) only given to those who need it.

When administrative accounts are created, they should only be used for that specific task, with standard user accounts used for general work.

For information on limiting your staffs ability to download or browse websites, contact our team for cost effective solutions.



Patching is a boring, untimely, annoying, yet absolutely necessary part of owning a computer, phone or other digital device. When you press “snooze” or ignore an update, it leaves your device and any network its on wide open to attack. Make sure you update AS SOON as one becomes available.


Tip 4: Control how USB drives (and memory cards) can be used

We all know how tempting it is to use USB drives or memory cards to transfer files between organisations and people.

However, it only takes one infected stick to devastate a whole organisation.

Reduce your chanced of infection by;

  • blocking access to physical ports for most users
  • using antivirus tools
  • allow only approved drives and cards within your organisation
  • scan any devices prior to opening documents
  • where possible, suggest a transfer programme or the Cloud as an alternative

Make these directives a part of your company policy.


Tip 5: Install a firewall

Firewalls are one of the main pieces of hardware which help protect your business. They are the first line of defence, no matter how small your business is.

Many home offices are now turning to firewalls as added protection and one which has buffered an unknown amount of attacks.

If you have multiple devices which require access to files from outside the workplace and need the use of internet or email, a firewall is a must.
