Do You Need to Buy Antivirus for Your Laptop or PC?
Many people believe that a new Windows laptop or desktop computer needs a paid antivirus package straight away. In most cases, that is no longer true.
Windows 10 and Windows 11 already include a comprehensive security system called Windows Security. At its heart is Microsoft Defender Antivirus, which provides built-in, real-time protection against viruses, malware and other threats—without requiring a separate subscription.
What protection is already included with Windows?
Windows Security is built into the operating system and starts protecting your computer from the moment Windows is running. Its main features include:
- Real-time virus and malware protection
- Quick, full and custom security scans
- Automatic security intelligence updates
- Windows Firewall and network protection
- Microsoft Defender SmartScreen for suspicious apps, files, websites and downloads
- Protection against potentially unwanted applications
- Security checks for features such as Secure Boot and TPM
You can check it yourself by opening the Start menu, typing Windows Security, and selecting the app. A green tick normally means that area is protected and no action is required. A yellow warning means Windows has a recommendation, while a red warning needs attention.
Is Microsoft Defender good enough?
For many home users, yes. If Microsoft Defender is active, Windows is fully updated and you follow sensible online habits, you may not need to pay for another antivirus product.
Microsoft Defender works quietly in the background, updates automatically through Windows Update and scans files as you use them. It also avoids many of the pop-ups, subscription reminders and extra programs that sometimes come with third-party security packages.
However, no antivirus can protect you from every possible scam. Even the best security software cannot always stop someone from voluntarily giving a password or bank information to a convincing fake website or telephone caller.
When might paid antivirus still be useful?
A paid security package can still be worthwhile if you want additional features such as:
- Parental controls across several devices
- Identity monitoring or data-breach alerts
- A password manager or VPN included in one package
- Central management for several family or business computers
- Extra technical support from the security provider
Businesses may also have different security, insurance or compliance requirements. In those situations, professional business protection may be more appropriate than relying only on the standard home setup.
Avoid running two antivirus programs at once
Installing more antivirus programs does not necessarily make a computer safer. Two security programs trying to scan the same files can cause conflicts, slow performance or confusing warnings.
Windows normally turns Microsoft Defender Antivirus off automatically when another compatible antivirus product is installed and active. If that product is removed, Defender should turn back on. It is still sensible to open Windows Security afterward and confirm that protection is active.
Good security habits still matter
Whether you use Microsoft Defender or a paid product, follow these important rules:
- Keep Windows, your browser and other software updated.
- Never open unexpected email attachments or suspicious links.
- Download programs only from trusted sources.
- Use strong, unique passwords and enable two-step verification where possible.
- Keep a separate backup of important photographs and documents.
- Be cautious when anyone phones claiming to be from Microsoft, your bank or an internet provider.
Our honest advice
For most everyday Windows users, the built-in Windows Security and Microsoft Defender Antivirus provide a strong starting point, and buying another antivirus package is not automatically necessary.
The important thing is to make sure protection is switched on, fully updated and working correctly. If you are seeing virus warnings, unwanted pop-ups, browser redirects or unusual slowdowns, do not ignore them.
