    Default VSMON Intense I/O Reads culprit (maybe)

    I think this is a Clue.
    I've been experiencing high hard drive activity for a while and using Process Explorer discovered the primary actor was VSMON.
    Using the System Information screen I could see that VSMON was reading many GB of data periodically.
    That didn't make much sense to me as I thought this was the firewall component of ZA 7 and didn't expect it to behave like a scanner.
    The only change I could identify was the switch from AUTO program control to MAXIMUM.
    I turned it back to AUTO and shortly I/O activity DROPPED OFF THE CHART.
    The chart had previously shown a sawtooth pattern
    of increasing I/O activity and than a drop off.

    Again this may be a clue.
    Since then I have turned it back on and nothing untoward has happened but it may take some other trigger or a reboot to recreate the previous issue.
    I'll let you know if it reoccurs.
    Does anyone know what causes this.
    Is it a bad thing or just the price of freedom (from nasty hostile code)?

    Operating System:Windows XP Pro
    Software Version:7.0
    Product Name:ZoneAlarm Internet Security Suite

    <p align="left">vsmon is the culprit, along with system.exe.
    I have been working this problem for the better part of the day and am quite annoyed.
    I downloaded a utility from PCMagUtilities called &quot;DiskAction 2&quot; that proves these two ZoneAlarm programs are grinding my system to a stand still for as long as 20 minutes at a time.
    From my last restart (which is really painful since this mess starts right from boot up and has increased startup time from 2-3 minutes to 30 at the worst) they have a combined Total I/O of more than 4 Gbytes.

    ZoneAlarm has crippled my system s start up since I began using it, but given that
    I usually leave my system on all the time I've just lived with it.
    This massive attack on my hard drive is a recent development and has caused me to seriously consider researching and purchasing a different security suite solution.

    I am running version 7.0.337.000, not running the Anti-virus (using my corporate Symantec license).

    Presently the file view shows vsmon.exe and system.exe reading a large game demo I downloaded last week.
    This is odd behavior at best.
    I haven t accessed that file since I downloaded and installed the demo.

    My major system components:
    1. Intel Core2Duo E6750 2.66 GHz
    2. 2 Gbytes Corsair DDR3 RAM
    3. MSI 7800GTX 512 PCIe
    4. Seagate SATA3 500 GB HD
    5. Seagate SATA2 160 GB HD x3

    I uninstalled, cleaned the registry with 2 cleaners, downloaded a new copy of the .448 version (the most recent) and reinstalled.
    So far, there has been no reoccurrance.
    I'm monitoring it with Process Explorer and this appears to correct the problem.
    However, only time will tell.
    This didn't occur for a month after the initial installation.
    I suspect that some other installation or defraging etc has damaged a file resulting in this behavior.
    I'm like you in that I can't understand why VSMON would scan everything.
    Maybe it is looking for a component .dll that has been moved.
    Possibly a cleaner removed somethat of value that led to this hunting trip.
    I'm pretty sure that reinstalling clean corrects the problem.
    Until something causes it again.
    Let me know if you have any success with this.
