Why is Java under Program Files and Windows?

I have moved on from discussing whether the Java files under the Windows folders are virus/trojan, because I have scanned them and they are the same size as those under the Program Files folders...


My question now is WHY does Java appear under both folders?


I have Java files under:


1) Program Files

2) Program Files (x86)

3) Windows\System32

4) Windows\SysWOW64


I've been told that Java will install under both Program Files and Program Files (x86) because there are 32-bit and 64-bit versions...but that doesn't explain why there are files under the Windows folders.





Hi MonarchDJ,


·         I presume you’re running 64-bit Windows 7, is that correct?


64-bit version of Windows has two directories: Program Files and Program Files (x86) for 64-bit and 32-bit applications respectively.


With respect to java appearing under Windows\System32 and Windows\SysWOW64, read on...


WOW64 stands for "Windows on 64-bit Windows", and it contains all the 32-bit binary files required for compatibility, which run on top of the 64-bit Windows.


File activity from a Win32 process that would normally go to the System32 directory instead goes to a directory named SysWow64. Under the covers, WOW64 silently changes these requests to point at the SysWow64 directory. A Win64 system effectively has two \Windows\System32 directories—one with x64 binaries, the other with the Win32 equivalents.


I’d suggest you to refer the following MSDN article for more information:
