Version 4 of Zemana rebrand Watchdog Anti-Malware, has just been released. It has a new UI you can see a screenshot of if you open the link.
It is still based on Zemana, even though there appears to be no v4 of Zemana yet. I'm not sure how it compares to Zemana v3 for malware detection.
Watchdog Anti-Malware is a second-layer, second-opinion cloud-based multi-engine malware scanner with real-time protection designed to protect your computer from malware that your primary anti-virus misses.
