Research on Computer Virus and Prevention Mechanism under the Background of Big Data

With the continuous progress of China's science and technology, big data and related concepts receive the wide attention from all sectors of society, network technology is extensively popularized and applied in the era of big data, and many changes appear in people's daily life under the influence of new technology. Big data is realized by cloud technology, and it refers to mass data resources stored in computer network system. Under the background of big data, the methods for people to obtain information change greatly. The application of big data technology in computer and network terminal is significantly advantageous. At the same time, various security flaws in network system and computer viruses bring serious security threat to users. Therefore, it is necessary to study strengthening prevention mechanism to ensure the secure and stable operation of network system. The popularization of computer network promotes the development of all walks of life. Whereas, various computer network securities bring troubles to users, even serious economic loss, which already arouses the attention of all sectors of society. At present, many institutions have stipulated measures for network system security problems to avoid system faults. The era big data brings great opportunities for improving network security and preventing computer virus. Therefore, relevant technicians shall strengthen research, formulate perfect control measures and prevention mechanism of network security, make use of new technology and give play to the advantages of network system, so as to make contribution for national development.
