How do you manually delete a file that may or may not be on the system without having to manually search for an unknown number of potential possibilities? I am asking this question in relation to Windows malware that includes a Java downloader component. Boonana used a Java downloader and it was cross platform. It was not particularly dangerous to Macs as the downloaded payload required authentication. But, it is not something you would want on your system. Malware writers could modify the payload downloaded by other Windows malware that uses a Java downloader to include Mac payloads. This could be done simply by modifying the contents at the download location and leaving the name unchanged. This would be a method to convert the malware to being cross platform on the fly. These potentially convertible Windows malware are also something you most likely do not want on your system. Especially, in the event that the payload includes privilege escalation as then it would not require authentication (priv esc very rare in OS X but still possible). I want to know whether it would be more efficient to manually search for all the possibilities or if it would be easier to find some app that would be able to locate this type of Windows malware and help remove it from the system? If using an app is more pragmatic, then any suggestion would be highly appreciated.
