We recommend that you install security software to help protect your computer from viruses and other security threats, and that you keep your security software up to date.

The companies listed below provide security software that is compatible with Windows. Just click the company name to see the Windows-compatible product they offer.

Important: Before you install antivirus software, check to make sure you don't already have an antivirus 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 antivirus products installed at the same time.
