Abstract
Systems and methods for protecting client computers are described. One method includes receiving webpage data at a proxy from a webpage before the data reaches an intended recipient; gathering scripting-language-data from the webpage data; normalizing the scripting-language-data so as to generate normalized data; emulating execution of the normalized scripting-language-data with a inspection-point-script-execution engine that that is adapted to provide inspection points instead of effectuating particular functions, and determining whether to block the data from the intended recipient by analyzing inspection-data collected from the inspection points.
