It's the best AV and I have been using it for years without problems. Small footprint. Easy to remove. Great support either here or via phone or email. They seem to care about the customers and work with them to solve problems. US support phone number (we both live in the US) and the support people speak English as a first language. The phone is answered by humans and you don't have to go through the press 1 or say 1 "dance." Never have been infected with malware using ESET. Any other suggestions that I can tell sister? She is ready to get ESET for her new computer, but husband wants to consult his "computer expert" at work. Thanks for the responses I know I will get. You guys and gals are always the best with valid and technical replies to threads here. Validation by others will help.
