How can I protect my computer with antivirus software?

One of the most important ways you can protect your personal computer (PC) is to download antivirus software and run regular scans. While no antivirus is 100 percent foolproof, there are now many free and often operating system-integrated products that help protect your machine from viruses and malware when paired with safe computing practices.


It is strongly recommended that you download and install one of the following antivirus products. Only download and enable one antivirus product; uninstall any and all other antivirus software installed on your computer to ensure optimal protection and performance.
