Best antivirus software
Assuming you don't want an avalanche of malware, including viruses, Trojan Horses, ransomware and other internet nasties, attacking your computer, kitting yourself out with internet security software is a must.
There's a bewildering amount of security software packages on the market, each claiming to give you great PC protection.
So we've whittled down the hordes to unveil the best antivirus software packages that impressed us most.
Do I need antivirus for my Windows PC?
Recent versions of Windows have these tools built in. Windows 10 offers the most complete protection; its updated version of Defender includes antivirus, firewall and anti-spyware capabilities.
If you’re using any earlier version of Windows, such as Windows 7, it's time to upgrade as Microsoft has stopped providing security updates for it.
How often should my antivirus software update and scan?
It’s vital to keep your computer’s antivirus protection up to date, otherwise newer threats may be able to slip past your defences.
Most security software automatically checks for updates at least once a day, although it’s worth investigating whether your program is set up correctly.
Your security software gives real-time protection against threats as they emerge, but regular system scans are important, too. Most security suites are configured to perform an automatic scan once a week, often offering the choice of a ‘quick’ or ‘full’ scan depending on your needs.
We recommend carrying out a full scan once a week. You can do a manual quick scan any time you choose if your computer is exhibiting suspicious behaviour.
