According to MRG Effitas, a UK-based independent IT security research company, Zemana AntiMalware proved to be the best rasnomware protection and got the highest score among globally known products. The full report you can find here.
Meh, the only problem with false positives is the people who just quarantine stuff without actually doing research. Otherwise, I don't care about FP's. I'm more inclined to like a product if it's more aggressive, regardless if it picks up FP's. But yeah, probably why pandora is disabled by default.
That has been asked multiple times. Ordinary users, like us, don't understand. But it's a corporate decision. We might see it as illogical, but they see it as logical given the corporate reality they are in (e.g. deals with those 3rd party companies).
If I remember correctly, one of the reasons why Zemana decided to hide the information about the 3rd party engines is the fact that ZAM might just become a tool of comparison. For instance, imagine a file detected by Kaspersky but not by Bitdefender, or vice versa, what could be a possible result? Debate. Word war. There would be comparison about which is the best.
Although, for me personally, I would like to know the participating 3rd party engines, too.
