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
Nobody manages to keep it simple, yet very effective, like ESET does.

Dragan M., ESET customer from Serbia
I use ESET NOD32 Antivirus on my PC and Mac at home, work and while traveling. It works quietly behind the scenes without ever interrupting what I do.

Debbie M., United States
Since switching to ESET several years ago, I've not had any intrusions to my machines; a problem I had with several other big name programs.

Debra G.M., United States
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.
