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.

Protection for other platforms. Microsoft is by far the biggest target for viruses and malware. While the Mac does come under attack via side-loaded apps, it's rare, and if you download apps only from the Mac and iOS app stores and keep your guard up when clicking links and download files, you should be OK without an antivirus app on Apple devices.

That way it will not interfere with your normal operations. To add icing to the caking, Avast is easy to use and has a nice clean interface. There are a few good features including an effective security check program. Avast is the best option for most XP users because it can be downloaded for free in a fully online version.
AVG — This good basic program is stable and fast. Both the look and feel of AVG are dated. It also lacks some of the standard features found in most antivirus programs. One advantage to AVG is that both online installs and full versions can be downloaded from its website. Kaspersky Free — Americans who are hysterical about Russia Gate will not like it, but this solution is still one of the best around. Kaspersky is the best antivirus program for dealing with a wide range of viruses and malware.
More importantly, Kaspersky is one of the few free antivirus programs with a good website and support. There are also a lot of free security tools available from its website. The only problem we had with Kaspersky was that there is no free full online version. Best of all it is a nice small program that takes up the lowest amount of computer resources of the solutions we tested. That means you will still be able to use your computer after it is installed.
The biggest advantage to Total Security might be ease of installation, both the online installs and downloads load fast and set up quickly.
