[QUOTE="cruelsister, post: 584906, member: 7463"] Duo- My apologies. I do remember (Kinda-Sorta) testing this one in the past and was not impressed. But (If I am correct) they have made great strides. The one really, really important thing to note is that AppCheck is a pure anti-ransomware product (and they specifically watch for encryption on a case by case basis instead of using either definitions or the stupid Group Policy restrictions used by other products currently- a better path to walk especially for truly novel and zero-day stuff) . This is important to note as it should never be expected to do anything other than what is its intended purpose. By this I mean if a ransomware product has something like a Pony info-stealer coded into it, Appcheck won't stop Pony although it probably will stop the file encryption process. Another example would be from a Private conversation I am having with Peter from Wilders- he brought up a CTBlocker variant which I totally forgot about. This one will spawn a daughter which would then run. On run, it would: 1). encrypt files 2). set itself up for persistence via Task Scheduling- so it will work on reboot via a legitimate svchost! 3). Cause a reboot via DCOM instead of the usual shutdown -r -s command Being a pure Anti-ransomware product AppCheck WILL stop the encryption process cold (even on reboot), but will NOT stop the spawning, nor the scheduled Task, nor stop the DCOM command . However the Pro version may (or may not) stop this process cascade by deleting the original vector. But as I don't speak Korean (nor do I like like Korean food) I haven't tested or verified this.
