Title

McAfee VirusScan On-Access Scanner All Processes settings actions, When an unwanted program is found must be configured to delete files automatically if first action fails. (Cat II impact)

Discussion

Potentially Unwanted Programs (PUPs) include Spyware, Adware, Remote Administration Tools, Dialers, Password Crackers, Jokes, and Key Loggers. While PUPs do not typically have any infections capability on their own, they rely on malware or other attach mechanisms to be installed onto target hosts, after which they will collect and transfer data from the host to an external host and/or will be used as attach mechanisms. Configuring the antivirus software to attempt to clean the file first will allow for the possibility of a false positive. In most cases, however, the secondary action of delete will be used, mitigating the risk of the PUPs being installed and used maliciously.
