    Can anyone please advise of the nature of the sub folder 'SysWOW64' on a
    Window Vista 64bit computer. It would seam to have attracted a large amount
    of viruses, but only to this area.

    Probably more than you are looking for, but:

    Everything You Need To Know To Start Programming 64-Bit Windows Systems

    Basically you have two (2) system folders, one for legacy 32bit
    dlls/coding [sysWoW64 - "W"indows "o"n "W"indows"64"], the other for
    64bit [system32 - old carry-over].

    What AV/anti-malware application(s) are you using and what are they
    supposedly finding?

    Is the system fully updated?

    64bit malware is a bit "newer" and requires a bit more to work
    effectively, so most likely you have 32bit malware/crimeware [not that
    that makes any difference now]..

    So what EXACTLY is it that you have found?

  3. [Crosspost to Win64-bit newsgroup]

    Always state your full Windows version (e.g., WinXP SP3; WinXP 64-bit SP2;
    Vista SP1; Vista 64-bit SP2; Win7; Win7 64-bit) when posting in a forum or
    newsgroup. Please do so in your next reply.

    What anti-virus application or security suite is installed and is your
    subscription current? What anti-spyware applications (other than Defender)?
    What third-party firewall (if any)?

    Has a(another) Norton or McAfee application ever been installed on the
    computer (e.g., a free-trial version that came preinstalled when you bought

  4. Robert is going after your basic virus questions, but to answer your
    question about what the SysWOW64 folder is -- it's the 32-bit version of the
    "system32" folder in a 64-bit version of Windows. Any 32-bit Windows
    applications, DLLs, etc, on your 64-bit Windows computer go in that folder.
    So it has 32-bit versions of CMD.EXE, for example, along with lots of other
    system applications. When you are running a 32-bit application, the SysWOW64
    folder _appears_ to be located at \Windows\system32, not at
    \Windows\SysWOW64. Only a 64-bit application can tell that the folder is
    located at SysWOW64.

    It is highly likely that you got infected by something nasty that was only
    32-bit aware.
