Techniques for categorizing programs running on an information handling system. One method includes, while a program is running on an information handling system in a manner that permits the program to infect the information handling system, calculating a first score and a second score. The first score is indicative of the likelihood that the program is malicious; the second score is indicative of the likelihood that the program is valid. This method further includes categorizing the program with respect to the likelihood of the program infecting the information handling system, including by categorizing the program as valid code based on the second score being above a threshold value, regardless of the first score.

Method, computer software, and system for providing end to end security protection of an online transaction

A method for implementing an online transaction security product includes downloading an online transaction security product program from a web site to an information handling system. The security product program includes an anti-malicious code program configured to detect malicious code on the information handling system. Lastly, the security product program is executed, wherein the anti-malicious code program of the security product program operates to detect malicious code on the information handling system.

A method for detecting malicious code on an information handling system includes executing malicious code detection code (MCDC) on the information handling system. The malicious code detection code includes detection routines. The detection routines are applied to executable code under investigation running on the information handling system during the execution of the MCDC. The detection routines associate weights to respective executable code under investigation in response to detections of a valid program or malicious code as a function of respective detection routines. Lastly, executable code under investigation is determined a valid program or malicious code as a function of the weights associated by the detection routines. Computer-readable media and an information handling system are also disclosed.
