HitmanPro.Alert is not an anti-virus solution and our CryptoGuard technology protects against crypto-ransomware (hence it's called CryptoGuard). If the machine is hit with other extortion malware (generally called ransomware), the current version of CryptoGuard in HMPA does not offer protection. The Hitler ransomware that was discovered is a development build. It is expected that the final production version will encrypt your data. That one will be stopped by CryptoGuard. That said, Hitler is currently not a real-world threat. Also remember, in most tests and videos (e.g. from GrujaRS) it's often only the ransomware itself that is under scrutiny. In the real-world, ransomware arrives on the machine through a dropper, exploit or Microsoft Word document with malicious macro attached to a spam e-mail. HitmanPro.Alert's Exploit Mitigations, Application Lockdown and Process Protection are pretty effective against these delivery methods. And in case of crypto-ransomware, which is by far the most prevalent ransomware, these are stopped by CryptoGuard without using signatures; meaning CryptoGuard also protects patient zero.
