摘要
Systems and methods for protecting client computers are described. One exemplary system includes an initial filter that gathers scripting-language-data from webpage data and a signature database of signatures of known scripting-language-data exploits. In addition, a parser generates a parse tree from the scripting-language-data, and a normalization and signature matching component reduces a complexity of the parse tree, generates a representation of at least a portion of a structure of the parse tree, and prevents the scripting-language-data from reaching an intended recipient if the representation matches one of the signatures of known scripting-language-data exploits.
