Computer Updates

Software companies work just as hard as we do to keep the bad guys at bay. Making sure your software is constantly updated could prevent some major problems down the line.

But my computer works fine - why do I need to update it?

Criminals, hackers and legitimate researchers constantly find new ways to attack computers. When software companies discover a new vulnerability, they release a software update so that you can eliminate the threat.

Is it risky if I don't update my computer?

Some updates cover 'critical vulnerabilities' which leave your computer wide open to criminals and hackers. We'd strongly advise you to download the latest software updates offered by your software provider.

But why do I need to update if my anti-virus software is up to date?

It may feel as though you are being overcautious, but updating software can bring performance improvements as well as adding new security features. Software updates might also protect your computer against viruses that go undetected by anti-virus software.

I'm no IT expert. Is it difficult to update my computer?

Not at all. Microsoft has automated the process to make it as easy as possible. To set up auto-update, go to Microsoft Windows Product Updates. For Microsoft Office products such as Word and Excel, go to Office Update. Apple users will need to go to Apple support.

How often should I update my computer?

Most computers can be set to update automatically every day. It's a sensible precaution, and you don't even need to think about it. For more advice on how to fight off intruders and hackers, visit Get Safe Online.

Firewalls

Firewalls sound pretty intimidating - and with good reason. They're the first line of defence for most businesses - and there's every reason for you to have one as well.

What is a firewall?

It's a piece of software that blocks unwanted traffic between your computer and the internet.

How does it work?

You can decide which of your programs are allowed to connect to the internet and which programs from the internet can connect to your computer. You can add programs that you trust, such as Outlook Express, to the guest list, and you can bar a program that wants to connect for dubious reasons. When a suspicious or unrecognised connection is identified, the firewall automatically identifies and blocks the attempt.

Do I need a firewall?

Yes, everybody should use a firewall.

I'm no IT expert - will I be able to do this?

Absolutely. Once a firewall is set up, it doesn't require much attention and most of them come with step-by-step instructions anyway.

Do I need to pay for a firewall?

The latest versions of Windows XP and Vista have Windows Firewall built in, and many commercial security software packages include firewalls. In addition, some good firewall software packages are free for non-commercial use - Zone Labs ZoneAlarm is one example.

Where do I get a firewall from?

If you are using Windows XP, look in the Control Panel to see if "Windows Firewall" is present and switched on. If it is not present, download Service Pack 3. You can buy commercial firewalls on the high street or you can download ZoneAlarm.
