I love this Security Company. I have taken it out online for 2 years and it does what it says it can! LOVE IT!

Philip Potter, Hastings, Victoria, Australia

Excellent service. Compared to other security suites. (I've tried them all.) It's comprehensive. It's not as resource hungry as most of the other security software out there. ESET does the job & stays out of the way.

Luke Huston, Sydney, Australia

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.

Deon Seymour

Fast, powerful and a very efficient engine. ESET software is my favorite and I will use it for a long time. Thanks for protecting my daily surfing.

Andrea A., ESET customer from Italy

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.
