Considering the threat that ransom ware poses to all businesses, it is possible that even small businesses and individuals may get trapped though they are not the primary target for the fraudster in view of their small value. While the big businesses need to secure themselves with the best of the tools with realtime updation and realtime back up facility, small businesses may need to look for a combination of personalized backup with a good anti malware software.
In this connection apart from the fundamental anti virus and anti malware software, there are some specific anti-ransomware tools that one needs to look for. Ransomware’s primary behaviour is “Encryption” and hence these anti ransomware tools may focus on spotting any signature that attempts to encrypt files.
The following page gives details of some of the available free tools in this regard. http://www.thewindowsclub.com/free-anti-ransomware-tools.
1] BitDefender Anti-Ransomware will immunize your computer. What it does is, basically it does not allow executable files from %appdata% and %startup% to run.
