Hello Bidzina Check this links https://www.quora.com/How-hard-is-it-to-develop-an-antivirus-software Its not an easly task to create a software like that.you want to create these level of software you need to bge expert programming There is no one-size-fits-all approach to malware analysis and virus detection. New techniques for compromising operating systems appear all the time. These techniques and methods are largely designed to defeat anti virus detection applications. You will need a solid understanding of the operating system you choose. You will need to know how the operating system works, how memory is managed, how access to resources are managed, etc. Not to mention, you will need to know how access to these resources is secured and permissions granted. You will need to know a low-level programming language. You didn't say what OS / platform (Mac, Linux, Windows, etc) you are interested in writing the AV software for. Assuming that you are going to target MS Windows, one of the largest sources of known viruses. In my opinion, the best language may be to learn C++. It’s possible to write AV software on the .NET platform but somewhat difficult due to managed code restrictions, etc. C++ would be useful on the Mac and it’s cousin C on Linux. Finally, in order to create an effective AV application you will need access to virus signatures. Signatiures define unique characteristics of the virus or malware itself. The signatures will help identify unique byte patterns or strings that are only found in various strains of known malware. Signatures can be somewhat difficult to create without a lot of resources and access to the malware itself. I would recommend you check out some open source anti virus software such as Clam AV. Clam offers AV software for Windows and Mac and Linux (http://ClamAV.com
