    Question Extreme Security on-access scanning slows program launching

    On-access scanning, no doubt, has its benefits. However, it consumes IMHO inordinate amounts of time. My system: a 2000 Sony desktop, a quad VAIO machine at 2.8 GHz with a GBy of RAM. Not this year's Formula 1, I admit, but a simple attempt to start Internet Explorer with on-access scanning turned on takes from 30 to 40 seconds before the Yahoo screen is fully populated, or two count them two seconds with OA scanning turned off. It's nice to be protected,~~BLEEP~~ Is there some middle ground between efficiency and protection? Before someone brings it up, the depth of scanning has no effect timewise.

    (Side issue. I complained via feedback about how difficult it was to access this screen. No doubt, I made some mistake or other. Nevertheless, I have no idea how I finally got here to ask this question. Par for the course these days, I suppose. )

    Sorry it is not clear what kind of issue you are having.
    It could resamble this: http://forums.zonealarm.com/showthread.php?t=73633

    Note that ZA staff does not monitor this board, we are all users here. If you have a valid license please contact the ZA technical support, its free for registered users.

    To see if you have simply too many programs running at boot (for the 1GIGA RAM), do this:

    1.) Click Start -> Run
    2.) Type MSConfig in the run box (or search box in VISTA) and click OK (ENTER in VISTA)
    3.) Once in MSConfig, click the Startup Tab
    4.) Remove the checks from everything except ZLClient
    5.) Click the Services Tab
    6.) Place a check in "Hide All Microsoft Services"
    7.) Now remove checks from everything other than TrueVector Internet
    Monitor and ForceField (if present), and click OK.
    8.) Restart your computer

    How does it work? Is it faster?

    NOTE: You can place your computer back into a normal startup process by
    going back into msconfig and choosing the Normal Startup option on the
    General tab.

    Thanks,

    I started off on the wrong foot here, with a non-explicit thread
    title and an initial post that needed bleeping (my apologies),
    in the wrong forum. Thanks for the response.

    I'll close this thread and am starting another one in the virus
    scanning forum.

    Question Extreme Security on-access scanning slows program launching

    I'm a long-time Zone Alarm user, since before I
    acquired my current computer. Since I upgraded
    from Zone Alarm to Zone Alarm Extreme Security
    (but not before), I've noticed that programs tend to
    launch noticeably slower. I finally got around,
    during the last few days, to investigating this.

    It appears that the slowdown is strongly correlated
    with whether or not On-Access scanning is enabled.

    Clearly, I expect _some_ time to be taken up with
    on-access scanning, but the amounts of time taken
    seem large to me. I have noticed no slowdown since
    the upgrade in any other respect than when launching
    a program. Due to problems with some Media Center
    tasks, I have worked extensively with my startup
    tasks and believe I have them pruned down to those
    that are necessary; I've become accustomed to
    using WinTasks to monitor strange usage patterns
    of CPU and VM, and haven't seen any lately.


    Here are some tests. Each individual test was made
    first thing after a fresh reboot.

    (1) My browser, Internet Explorer 8, version
    8.0.6001.0187021C;

    with OAS, 19 to 28 seconds to produce a window, plus
    10 to 14 seconds to load my home page, ca.yahoo.com

    without OAS, 3 seconds to produce the window, plus 5
    seconds to load the home page

    in either case, loading another reasonably complex page,
    www.chapters.ca, takes 5 seconds (note that the home
    page takes longer with OAS on, indicating more scanning
    is being done after the blank window appears).

    (2) My mail and news program, Outlook Express 6,
    version 6.00.2900.5512;

    with OAS, 23 seconds to fully load and show the contents
    of my Inbox

    without OAS, 2 seconds to produce the same display.

    (3) My word processor of choice, WordPerfect X3, opening a
    file consisting of a complex collection of tables that are
    interrelated and take 46 pages to print -- this is an example
    of an application that really exercises my machine's
    capabilities;

    with OAS, 13 seconds to produce the first visible result, the
    WPX3 "splash", plus 9 more seconds to produce the full
    window with the first page of the application

    without OAS, 2 seconds to produce the splash, plus 6 more
    seconds to produce the full window.

    (4) For a change of pace, a really simple little application,
    one of the old Windows Entertainment Pack card games;

    with OAS, 11 seconds to fully load (I doubt there are more
    than a handful of small files involved)

    without OAS, so fast it loads virtually instantaneously,
    nominally 1 second.


    Regarding On-Access Scanning, I always use the
    recommended Scan In Smart Mode setting.

    Here's my version information:

    ZoneAlarm Extreme Security version 9.0.114.000
    TrueVector security engine version (same)
    Driver version (same)
    Antivirus/Anti-spyware engine version 8.0.1.33
    DAT file version 1017991328
    AntiSpam version 6.0.0.2383
    ZoneAlarm ForceField 1.5.36.15

    My operating system is Windows XP Media Center
    Edition, version 2002 with Service Pack 3

    My machine is a 2006-vintage Sony VAIO desktop
    with a Pentium D CPU at 2.80 GHz, 1 GBy of RAM.
    Drive C: occupies 241 GBy of a 300 GBy drive,
    almost all of the rest being an Acronis Secure Zone
    (a partition visible only to Acronis True Image, in which
    an image may be stored). I currently use 50.4 GBy
    of C:; I periodically defrag it, and it's indexed for
    fast file searching.

    Has anyone else observed similar behavior, or does
    anyone have any suggestions? Thanks for any
    thoughts.

    Moved everything in one post... to avoid dispersion.

    Please try what already suggested and update ZA Extreme to latest version, yours is very old.

    Thanks for your suggestions, which turned out to be
    very much to the point.

    Your System Configuration procedure did indeed speed
    up program launching. I'll follow this up further to see
    if I can isolate startup items or services that are
    responsible, but that will have to wait until the weekend.
    Strange that whatever combination of items is responsible
    should interact specifically with on-access scanning.

    I've downloaded the latest Extreme Security release,
    and will install it. But that too will have to wait for the
    weekend.

    I'll post further when I find out more. But for now I at
    least have a way of launching programs at a reasonable
    speed. Two, actually (the other being to disable
    on-access scanning just long enough to load things,
    and then to restore it, but that in itself takes a number
    of seconds).

    Glad to hear it worked, now you have to find the culprit. Slowly enable back, first the items in services then in startup.

    Note that your ZA version contains an old ZA antivirus engine. You should update to the latest. This may also be the problem.

    Try also NOT to keep ANY setting while updating. Start from scratch and do not touch any default settings.

    And finally you have always the official support to contact. As already said we at just users here.

    Cheers,

    Smile Re: Extreme Security on-access scanning slows program launching

    Thanks again. I had time today to work on System
    Configuration some more. After I followed your procedure
    again, it struck me, this works fine, I'll just leave all this
    stuff unchecked for now; with two exceptions, a task and a
    process belonging to Acronis True Image. The difference
    between annoyingly slow and acceptable amounts to a
    net reduction from 47 tasks to 30, resulting in a "resting"
    memory usage drop from 34% to 22%. The numbers come
    from WinTasks. I note that many unchecked processes
    become checked again as the system boots, which I
    expected. I'll recheck more Startup items only as needed
    until I try the newer ZAES in coming days.

    The effect of on-access scanning, observed in WinTasks,
    is a spike from close to zero up to 50% plus of CPU until
    launching is complete.

    Apparently my system was on the edge of losing some
    efficiency, and the extra work Extreme Security does
    compared to vanilla Zone Alarm was enough to tip it over
    that edge.

    Cheers. First real summer weather today in Vancouver BC.
