Founded in 2002 and headquartered in the United Kingdom, BullGuard developed a reputation as a reliable antivirus provider with a focus on home users, families, and gamers. Their services stood out for blending strong, multi-layered threat detection with performance optimization features—most notably their Game Booster, which allowed users to enjoy lag-free gaming while staying protected. BullGuard’s security suite included essential tools like real-time protection, a configurable firewall, encrypted cloud backup, and a secure browser for financial transactions. Their interface was praised for being user-friendly, especially for non-technical users, and they performed consistently well in independent lab tests from AV-Test and AV-Comparatives. While macOS and mobile support was limited compared to Windows, BullGuard maintained a loyal customer base thanks to their practical features and straightforward approach to cybersecurity. In addition to strong malware defenses, they offered useful extras such as a vulnerability scanner, customizable parental controls, and system optimization tools, making them a well-rounded option. In 2021, they were acquired by NortonLifeLock, and by mid-2022, all BullGuard products and services were fully migrated to Norton’s ecosystem, ending standalone BullGuard offerings.
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.
