Emsisoft's Behavior Blocker detects almost everything that is not known by it as suspicious malware. Hundreds of times on my PC, it blocked uninstall.exe of programs while uninstalling. Yesterday, I was installing Adguard on Windows and the Behavior Blocker prompted 5/6 times while installing. It's usually detects those as "CodeInjector", "HiddenInstallation" etc. I have to choose "Wait, I think this is safe" every time. Someday, I would probably be attacked by a real malware and I would choose that one safe too because that's what I have to do usually. This has become so frustrating for me that even though I have a license of Emsisoft, I uninstalled it yesterday.
Now it detected Firefox too!!! That's sad.

Something modified firewall rules right before Firefox injected into another process, both times the user was given the option to say it was safe. Clearly some investigation needs to occur but people seem to prefer bashing the program, interesting.

I always find it interesting when people scream false positive. I reimagined almost every if I get a weird warning (which is rare). Usually I don’t get it again.

For those that are worried about ssd write cycles: replacing an ssd is cheaper than a Trojan or keylogger exfiltrating your sensitive information. Just my opinion.
