Your log indicates that you are using a 64-bit system. WOW64 is the x86 emulator that allows 32-bit Windows-based applications to run on 64-bit Windows but x86 applications are re-directed to the x86 \syswow64 when seeking the x64 \system32. For a more detailed explanation, please refer to Making the Move to x64: File System Redirection. Be aware that many of the tools we use for malware removal are designed for 32-bit systems and do not work or can give misleading results on 64-bit machines. For instance, running HijackThis on a 64-bit machine may show log entries which indicate indicate (file missing) when that is NOT the case. Anti-malware scanners have problems enumerating the drivers and services on 64-bit machines so they do not always work properly. Since this is the case, any assistance we can offer is limited.
