Mal/ZAUMem-C is a malware threat, which is a component of a new version of ZeroAccess malware. Mal/ZAUMem-C might be difficult to detect and uninstall from the contaminated computer by many anti-malware programs. HPmal/ZAccess-A has persistence if it automatically reloads itself when the computer user logs off and logs back on, or when he/she restarts the PC. That makes Mal/ZAUMem-C more dangerous, as it generally serves the attackers for a longer period of time. But the creators of Mal/ZAUMem-C also use the right-to-left override (RLO) and several other non-printable Unicode characters in both file paths and registry entries to further evade detection and extermination of the ZeroAccess components. RLO is often used by cybercrooks to conceal the extension of malicious .exe files. Mal/ZAUMem-C adds the files into a new location by using the ACL trick. Mal/ZAUMem-C replicates itself to two locations: in the %Program Files% folder, and in the user's local AppData area. Each copy is located in a folder that appears as though it is incorporated in a Google software product, using non-printable Unicode characters that make it difficult to notice on some versions of Windows. Mal/ZAUMem-C connects to the peer-to-peeer network and drops modules that primarily perform click fraud.
