Software can be protected through various methods, including copyright, which legally safeguards the code and content, and patents that cover unique algorithms or processes. Additionally, using encryption can help secure the software from unauthorized access, while licensing agreements can control how the software is used and distributed. Implementing robust security practices, such as regular updates and code obfuscation, further enhances protection against reverse engineering and vulnerabilities.

The code is protected as a literary work.
Computers are susceptible to viruses unless they are protected by special software and firewalls.
Software is protected by copyright as a literary work.
Anything other than open source software is protected by copyright; shareware and freeware may be free, but are still protected. Software that is purely functional (e.g., assembly code to perform a basic operation) is not copyrightable. Software created by any employee of the US government is not copyrighted in the USA.
Copyright law ostensibly prevents unlawful distribution, but technical preventions such as DRM tend to be more successful.
Because registration is not required for protection, there is no way to tell how much software has been protected by copyright. On the other hand, since protection is automatic, you can also say that all software is protected by copyright.
It is how the software is being protected with encryption or as simple as a password. These things help the software be safe from the files failing of being destroyed by hackers.
