And if you are a US government employee or work with the federal government, you'll want to steer clear of Kaspersky internet security products -- and perhaps use one of the antivirus software products mentioned here instead. Picking the best antivirus software for Windows means finding one that keeps your PC safe, doesn't take up a lot of system resources, is easy to use and stays out of the way till you need it.

And it watches for shady websites and suspicious links to keep you out of trouble. It can also offer ransomware protection and monitor unexpected behavior that may be a sign of new and not-yet-identified viruses and malware. You want antivirus software that can successfully identify these unknown online threats without flagging too many false positives.

Light on system resources. You don't want antivirus software that taxes your PC's resources. If after you install the program, websites open slowly, apps download or open sluggishly or file copies take longer than expected, you may want to try another service. The good news is, all our picks offer a free trial to let you try out the antivirus program, so if your system feels sluggish after installation, you may want to keep looking.

Cost and discounts. Don't just pay the sticker price for antivirus protection. Before you buy, check for discounts on a company's website. Another way to save: The prices we list above are for 10 devices -- if the company offered that package -- but you can trim your cost with antivirus packages if you need to cover three or five devices.

You may also find discounts on an app's Amazon page. To be effective, antivirus software needs to monitor what's going on with your PC, check in with company servers about unusual behavior and should provide sound banking protection.
