This is really an important question to think about. To avoid complexity windows generally, hides the file extension. For a novice user if a file is not opening correctly or he is getting any error while opening a file then he feels that his system is at real threat. However, it is not always true.
Sometimes there are some files for which windows does not find the appropriate program, and prompt the following message.
The basic reason that Windows cannot open the file, because the file that you are trying to open may be associated with some inappropriate program or the associated program is unavailable on your system.
This situation can be easily handled by either selecting an appropriate program from the list of installed window programs or one can search over the web for the appropriate program.  Now a day there are many software’s which helps you to find the appropriate program for the file you wish to open.
However, in the worst of situations sometimes file extensions are changed by some malware or ransomware. One of the most common examples is CTB Locker (Curve-Tor-Bitcoin Locker), or Critroni, which is one of the file encrypting ransomware. Therefore, it is always suggested to have an updated anti-virus and anti-malware installed on your system.
