    Default ZAX Excessive vsmon.exe CPU usage while downloading

    I've been using Zonealarm for years without issues. Today I decided to download the 6/25/2010 update and I noticed whenever I start downloading something vsmon.exe IMMEDIATELY spikes in CPU usage (ramping up as download speed increases) up to 50% and my whole OS starts getting laggy. The second I pause or stop downloading it goes away.

    Is there any way to fix this problem? If not, please direct me to a link to download the pre 6/25/2010 version of Zonealarm Extreme Security.

    as ever vsmon is the filter to all activities in your system. Historically two are the main issue related to vsmon picks. Potentially corrupted settings in ZA and conflicts with third party software.

    Granted you don't have other issues on the system (corrupted OS or not updated), malware related problems, you are on the latest ZA version and that you are not running other security tools.

    For issue related to ZA databases corruption you can reset them by:

    1.) Hold down the Ctrl and Shift keys together
    2.) Right click on the ZA icon near your clock
    3.) Choose 'Reset' from the box that comes up
    4.) Choose Yes on the Reset Settings dialog box
    5.) When prompted, choose OK to restart your system
    6.) Follow the on screen configuration prompts after reboot

    For issue related to conflicts with third party software:

    1.) Click Start -> Run
    2.) Type MSConfig in the run box (or search box in VISTA or windows 7) and click OK (ENTER in VISTA or in windows 7)
    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?

    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.

    It is also not recommended to run old versions of ZA. Please contact the official ZA support for troubleshooting your issue and, if the case, downgrading to an old version. Link to support in my signature.

    You didn't mention what version you upgraded from?

    Anti-virus took a major change in 9.x

    We no longer have separate processes running for AV its all now contained in VSMON.

    So you very well could see more cpu cycles being used by vsmon when compared to your previous version but that's normal and collectively we are not using any more resources than before. In fact we use less now by getting rid of the extra applications running.
