I got the one year free license posted here in April and have it installed with Windows Defender with no problems. Two processes in Task Manger show that it's a rebranded Zemana Antimalware. I'm not sure what others think about it being a good deal at that price. But I got a life time license for Malwarebytes Antimalware a few years ago for 10 bucks.
@generalwu: For me I will go to the program which came from the original ones, sometimes having same component with different names tends to be fishy already.
No questions for Watchdog as long it maintains the overall behavior.
