Consumer antivirus software providers for Windows

If you’re running Windows 10, Windows 8.1, or Windows 8, you’ve already got Windows Defender built in, helping to protect you against viruses, spyware, and other malware.

Malware consists of viruses, spyware and other potentially unwanted software. Windows Defender is free and is included in Windows, always on and always working to protect your PC against malware. If you have Windows Vista or Windows 7, you may use Microsoft Security Essentials  to help protect your personal or small business PC against malware.

Hackers and scammers sometimes use fake antimalware software to trick you into installing viruses or malware on your computer. Should you wish to explore alternatives to the already installed or available Microsoft antimalware software on your Windows PC, the reputable security companies listed below provide consumer security software that is compatible with Windows. Just click the company name to see the Windows-compatible product they offer. For business security software that is compatible with Windows, please contact your security vendor of choice.

Many companies, including those listed on this page, distribute anti malware software. You should carefully investigate the source of anti malware and other products before downloading and installing them. For more information, see Protect your PC.

Important: Windows Defender and Microsoft Security Essentials will turn themselves off if you install another anti malware program to protect your PC. Before you install anti malware software, check to make sure you don't already have an anti malware product on your computer. If you do, be sure to remove the product you don't want before you install the new one. It can cause problems on your computer to have two different anti malware products installed and running at the same time.
