Not all anti-malware investigative and disinfection tools will work on a 64-bit system
Microsoft created a new folder (C:\Windows\SysWOW64) that contains all the 32-bit .dll files required for compatibility which run on top of the 64-bit version of Windows. 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
and WOW64 Implementation Details
. 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
always the case. Anti-malware scanners and many specialized fix tools have problems enumerating the drivers and services on 64-bit machines so they do not always work properly.
If you cannot complete a step, then skip it
