| 1. A method, comprising:
receiving a first request via a browser application running on a first client computer system, wherein said first request
is for a first website usable by said first client computer system for performing an online transaction;
subsequent to said first request and prior to completion of the online transaction, sending a first program to said first
client computer system, wherein said sending causes the first program to automatically execute repeatedly within said browser
application during the online transaction in order to determine whether malicious code is currently running on said first
client computer system;
wherein, if the execution of the first program indicates that malicious code is currently running on the first client computer
system, perform a corrective action with respect to the malicious code.
