Research of comprehensive anti-virus for network device

In the fields of anti-virus technology, characteristic code technology has been the main approach for many years. Heuristic scan skill of computer virus developed in the recent years is still with many insufficiencies. Therefore, there are difficulties to seek and kill Trojan horse backdoors, which become more and more similar with normal programs. In view of these problems, starting from independence of dataflow and the shortcomings of system and application, the study adopts strategy anti-virus technology to resist various harmful procedures. The infected action link of malicious code is analyzed and, in order to improve the anti-virus effect, it is also used as the main theoretical basis to be connected with current anti-virus technology.
