Dealing with genomes, considering the distribution of mathematically determined sequences, looking for stable possible subchains, searching in general as a software problem by various criteria, are ones of the most necessary tasks when handling with actual research tools in the virology area. The range of urgent objectives currently includes the creation of new primers for virus diagnostics on stable areas of the genome and determination of the virus mutation sets, classification and clustering of the accumulated material for more accurate research, further mutation directions, etc. Computing complexes construction based on databases and the expansion of their functionality using online technologies, as well as the launch of server applications, is a function of the practical section in the field of programming for more efficient work of virologists and specialists from relevant fields in the areas of diagnostics and treatment of viral diseases.
