System and method for securing computers against computer virus

摘要

In one embodiment, an antivirus mechanism builds an automaton of a virus using a pattern and a set of rules. The antivirus mechanism may then scan a binary file to detect an engine of the virus by matching the automaton with a plurality of disassembly codes derived from the binary file. The pattern may comprise a data structure including a name of a particular virus, and information for detecting the virus using the disassembly codes.
