Founded in 2013 and headquartered in Toongabbie, New South Wales, Defencebyte is an Australian cybersecurity company offering antivirus software for Windows devices. Their antivirus solution includes real-time protection, behavior-based threat detection, automated scanning, and system rollback tools. The software is designed to run quietly in the background without slowing down performance, which is especially useful for users with legacy systems. Defencebyte offers multi-device coverage, flat-rate pricing, a 30-day free trial, and a 30-day money-back guarantee. While their products haven’t been reviewed by major independent testing labs and their online activity has slowed since 2022, users have praised the tool’s simplicity and ease of use. For those looking for minimal, real-time antivirus protection with low system impact, Defencebyte may still be worth considering.

Known for their intuitive interface, iolo’s software includes automated maintenance features like ActiveCare® for hassle-free optimization. Customers have praised the effectiveness of iolo’s products, as well as the responsiveness and professionalism of their support team.

Despite some criticism, iolo offers a comprehensive all-in-one solution, combining security, privacy, and performance optimization.
