BitDefender Anti-Ransomware Download
The program “protects against known and possible future versions of the CTB-Locker, Locky and TeslaCrypt crypto ransomware families”.
BDAntiRansomware requires installation, but by default displays no interface, and doesn’t consume any significant system resources. It doesn’t present any difficulties with false positives or anything else, but if you do run into problems, protection can be temporarily disabled.
The program doesn’t require that you have any other Bitdefender software installed, and it doesn’t require any extra marketing payload (there’s no registration required, browser pages didn’t start opening at the Bitdefender site).
BDAntiRansomware is no substitute for a full antivirus tool but right now it appears to offer a worthwhile second layer of protection to your existing security suite.
BDAntiRansomware is a free application for Windows 7 and later.
