Compare all products for Windows

ESET, you are absolutely the finest in researching threats and malware. That's why I will never use any other antivirus software and I love that I upgraded to Smart Security. Your software is worth every penny. I am forever grateful to you and all that you do.

ESET Smart Security was tested by AV-Comparatives and found to work the same way on Windows 10 as it does on Windows 8.1.

I'm in IT, as a support consultant, and I cannot stress how many times I come across a machine that is running "Free" protection that has been compromised. ESET products are well priced, well supported and besides using a fraction of system resources compared to other brands, they are effective."
