Since the only way to truly detect ransomware is based on its behavior, you’re absolutely right, one or two files may be lost in some cases.

Unfortunately, many ransomware strains target the Shadow Copy and delete it during the attack. Backups are critical, as well as behavioral detection of an attack, since backups will never be as frequent as you need them to be.

TL;DR - yes, in the case of ransomware, RansomFree delivers great value over any other product out there today, paid as well as free.

Hi, this is definitely a false positive. We’ve contacted Baidu to update their detection output. Thanks! -Cybereason
