Windows 7: the complete guide

Keep your computer secure

Discover the tools and tips you need to prevent your computer and personal data from coming under attack


Make sure you scan downloaded files before opening them

Protecting your PC from viruses, spyware, hackers and other threats is nothing new and, while Windows 7 includes some handy technologies to help protect you against such threats, there are still plenty of things you need to take care of yourself to ensure it's as secure as possible.

First, click 'Start' and select 'All programs > Windows Update'. Click 'Change settings' and make sure updates are set to be installed automatically. This ensures Windows receives all updates, including critical security ones that make your PC less vulnerable.

Next, you need to make sure you're protected by security software. An all-in-one package like Norton Internet Security 2012 ( is best, but if you can't afford to pay for security, install free anti-virus software like AVG Antivirus Free 2012 and a strong, third-party firewall such as ZoneAlarm Free Firewall 2012. You'll find these on the cover disc.

"Only download software from reputable sites and don't assume an email attachment is safe"

Stay protected Check your antivirus and firewall are both running and make sure they're regularly updated. This should be automatic, but one tell-tale sign of infection is if the update process stops working.

Also make sure your antivirus tool is performing regular scans to catch any infections that might slip past its real-time protection.

You can also take extra steps to beef up your security – the three tools mentioned below will do a lot to help in this regard but, as always, prevention is better than cure.

Only download software from reputable websites (like the program's own site) and don't assume any email attachment is safe. In both cases, save the program or attachment to your hard drive, then right-click and select the option to scan it with your antivirus tool to make sure it's not harbouring malware.

Avoid scams

An increasing phenomenon is 'phishing' – the use of fake emails and websites to trick people into giving up sensitive personal information.

Never respond to emails asking you to click a link, or offering you something that's too good to be true.

Always log on to any website by typing the web address into your browser manually (or using a link saved in your Favorites) and only shop on trusted, known websites.
