Yes I like Zemana. More so than many other companies. Not many companies take the time to talk to their user base so they also have my respect and trust. On top of listening to the user base, they have also added some features and fixed bugs quickly that were reported to them unlike some others.
Keep in mind AM is used mostly for malware removal (infected system) and it has done a much better job at doing that than any other tools that I've used. AntiLogger could always use more work obviously. Still doesn't protect the user in certain areas. But then again, no other software does 100% of the work either. I plan to add AntiLogger to my security config later beside Norton and Malwarebytes Anti-Exploit.
As far as I know, AM real time only detects files during execution unless you scan it manually so expect your AV to detect first unless it's set to on access only. I'd imagine it does this to avoid conflicts with your AV. When you run a malicious file, Zemana instantaneously catches it. For it being just put out to the public not that long ago, it's awfully good at what it does. My experience with Zemana products has been without any bugs so far.
For those using ZAM for their main AV, I'm sure you'll be fine. After all it does have behavioral analysis via Pandora (hope I got the name right - not on my Windows OS right now) so real time isn't it's only defense.
