    ok first is first I am using a HP Pavilion dv6000 laptop, windows vista home
    premium, 1GB of RAM and 3.1 GB redyboost, but for some reson 80% of memory is
    used up and what is using it up is 12 svchost.exe 5 in system 3 in network
    services and 4 in local services.
    I already know that svchost.exe is a backdoor program.
    now what I am wondering is there any way to fix this so that I can start
    programing?

    You need to control what you have running in the background. Svchost.exe
    is not a "backdoor program" although it can be used by malware; it is a
    legitimate part of Windows and it is normal to have several instances
    running. Twelve is rather a lot, and I'd start by checking the computer
    for viruses and malware:

    http://www.elephantboycomputers.com/page2.html#Removing_Malware

    If the computer is clean, examine your startup and remove unnecessary
    programs from it. You can see what is starting with Windows by using the
    System Configuration Utility and/or the free AutoRuns program:

    Start Orb>Start Search box>msconfig [enter]

    If you are prompted for an administrator password or for a confirmation,
    type the password, or click Continue. Then see what is on the Startup
    tab. You don't need to restart immediately, but the next time you do
    you'll get a dialog saying you've used the Utility. Usually in Vista
    this will be blocked by Windows Defender and you'll need to allow it so
    you can then tick the box that says in effect, "don't bother me about
    this again".

    Important - Do not use the System Configuration Utility to stop
    processes. Instead, use Start>Run>services.msc [enter] and do not stop
    any services unless you really, really know what you're doing.

    http://www.microsoft.com/technet/sysinternals/default.mspx - for AutoRuns

    It is always preferable to manage programs startup from within the
    programs themselves and only use msconfig/AutoRuns if it is impossible
    to do that.

    Also, 1 GB of RAM is not enough to have a good experience with Vista and
    the Ready Boost will not help appreciably. Increase your physical RAM to
    2GB.

    My Pavilion m8047c desktop has 2GB Ram and also 4GB readyboost. Memory
    usage is usually 45% to 55%, sometimes higher or lower, 55% as I type this,
    so I would think that 80% on 1GB Ram would be normal. Readyboost does not
    increase memory, it just makes your computer more responsive because
    readyboost cache is faster than disk cache.

  4. Read Malke's good answer, but also note that having 80% of memory
    "used up" is not any sort of problem at all. Wanting to minimize the
    amount of memory Windows uses is a counterproductive desire. Windows
    is designed to use all, or nearly all, of your memory, all the time,
    and that's good not bad. Free memory is wasted memory. You paid for it
    all and shouldn't want to see any of it wasted.

    Windows works hard to find a use for all the memory you have all the
    time. For example if your apps don't need some of it, it will use that
    part for caching, then give it back when your apps later need it. In
    this way Windows keeps all or most of your memory working for you all
    the time.

    Svchost.exe is not a backdoor program. Svchost.exe does nothing on its own.
    It's the messenger for O/S's programs and other programs. Svchost as its
    name implies host other programs and does the biding for other programs,
    acts on their behalf, and provides the means, including malware.

    You can use Process Explorer (free) to view all processes any given process
    like Svchost.exe is hosting. PE --- View/Show Lower Pane, Show All Dll(s) --
    that will show everything in the lower pane that a process in the upper pane
    is hosting. You can right-click a process in the upper pane and go to
    Properties to get more information about a running process. You can do the
    same thing in the lower pane.

    <http://www.windowsecurity.com/artic...d_Rootkit_Tools_in_a_Windows_Environment.html>

    Active Ports doesn't run on Vista. You can use CurrPorts, if you need to be
    in that area.

    If Svchost.exe is not running out of the C:\windows\system32 folder, then
    it's a Trojan, a backdoor, and an impersonator.

    If you're going to be programming, then you should know who is what and who
    is doing what in regards to the O/S.
