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.
Founded in 2003 and headquartered in New Zealand, Emsisoft is a cybersecurity provider known for developing lightweight, high-performance anti-malware tools for Windows users. Their software uses a dual-engine scanner to detect and remove a wide range of threats, including viruses, ransomware, spyware, and potentially unwanted programs (PUPs). Emsisoft’s products include real-time protection layers, behavior-based threat detection, remote management, and tools like an Emergency Kit maker for cleaning infected systems. Features such as RDP attack monitoring, scheduled scans, and MITRE ATT&CK mapping are designed to meet both personal and business security needs. Plans are divided into three tiers: Anti-Malware Home, Business Security, and Enterprise Security + EDR. Users praise the platform for its fast performance, intuitive design, and responsive support, though some note limited macOS/Linux compatibility and no browser cleaner.
