Every year, the second Monday of February marks Clean Out Your Computer Day, a perfect reminder to spend some time decluttering, organising and securing your data. Computers and networks require regular maintenance to ensure their security and efficiency is retained, so make time to tackle those cyber hygiene tasks that often get overlooked!

1. Remove Ex-Employees’ Access Immediately

One of the biggest security oversights in businesses is forgetting to take steps to prevent ex-employees’ access to company networks and accounts. If a former employee retains access to sensitive information, it can pose a serious security risk.

Ensure that:

• Their email accounts are disabled.

• Their credentials are removed from all internal and external systems.

A clean break from company systems reduces the risk of data leaks or security breaches.

2. Stop Using Outdated Software

Using old, unsupported software is like leaving your front door unlocked—it’s an open invitation for criminal hackers. Having software that is no longer supported means that they do not receive security patches and updates, making them vulnerable to attack.

Ensure that you:

• Uninstall any outdated or unused software.

• Replace it with a supported and up-to-date version.

• Enable automatic updates to ensure you always have the latest security fixes.

  
  

3. Protect Your Network and Devices

A strong defence is the best way to protect against malware and cyber-attacks. Keeping your system protected with updated anti-virus software is a simple yet crucial step.

So, make sure you:

• Install reliable anti-virus and anti-malware software.

• Enable automatic updates for both security software and your operating system.

• Regularly run a full system scan to detect any lurking threats.

  
  

Some Bonus Tips for a Cleaner, Faster, Safer Computer

• Declutter Your Files: Delete unnecessary files, clear your downloads folder, and empty your recycle bin.

• Organise Your Inbox: Unsubscribe from spam emails and use filters to keep things tidy.

• Back Up Important Data: Use cloud storage or an external hard drive to back up essential files but remember to keep them apart from your device or network so they are safe.

• Strengthen Your Passwords: Update old weak passwords and consider using a password manager for extra security.

  
  

Andy Dunbobbin, Police and Crime Commissioner for North Wales commented: “Ensuring people manage their data well is a crucial part of staying safe in the digital sphere, that’s why campaigns like National Clean Out Your Computer Day are so important.

“As someone with a professional background in IT, I know that organisations like the Cyber Resilience Centre for Wales and North Wales Police’s Cyber Crime team are able to offer helpful and current guidance on how to stay safe in the digital world, both as individuals and businesses.

“I would urge everyone to ensure their devices are decluttered, their software is up to date, and that networks and passwords are secure. That way we can help protect ourselves, our families and our communities from the damage of cybercrime and digital insecurity.”
