Abstract: Lists of keywords by type are collected that are associated with fake antivirus software. One more rules are created including the keywords that likely indicate fake antivirus software. The keywords and rules are stored in a local database on a computer. Each executing process of a computer is scanned using the rules. A match indicates that the scanned process is likely fake antivirus software. A check is then performed to determine if the scanned process is actually legitimate antivirus software (using a digital certificate, a white list, or a call to a function). If the check fails a determination is made that the identified process is fake antivirus software. The process may then be displayed, cleaned, quarantined, or permanently removed from the computer. The cursor may be dragged into the window of an executing process in order to selectively scan that process only. Or, any number of executing processes may be selected to be scanned by the rules.
