Many companies, including those listed on this page, distribute antimalware software. You should carefully investigate the source of antimalware 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 antimalware program to protect your PC. Before you install antimalware software, check to make sure you don't already have an antimalware product on your computer.

It can cause problems on your computer to have two different antimalware products installed and running at the same time.
