More Information
W32/Porex-C infects files with EXE file extensions by prepending itself to them. The virus attempts to terminate several anti-virus and firewall related processes.
W32/Porex-C tries to gather password information in the background by scanning the content of open windows for keywords and emails the collected information to a mail account in Russia.
When an infected program is executed, the virus extracts itself to a file with the extension RNT and the same filename.
The virus creates the files:
<Windows folder>\logger.bin (containing the gathered information)
<Windows folder>\poserv.exe (containing the virus code)
The file poserv.exe is registered as a new system driver service named "PO system service", with a display name of "PO system service" and a startup type of automatic, so that it is started automatically during system startup. Registry entries are created under:
HKLM\SYSTEM\CurrentControlSet\Services\PO system service
HKLM\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_PO_SYSTEM_SERVICE
