    Just installed. Will keep an eye on it to see if it becomes disabled again. Thanks.

    Did not think it would be since Andreas did not mention it. Just installed it to test. What AV are you using it with?

    Correct.
    I do not install unsigned softwares.
    I wonder if, in this case, also enabling the other rules there may be FP.
    And of course if this is necessary.

    I know but I don't want to break normal windows functionality where it forces me to disable OSArmor to achieve something, so I slowly testing them out. Example these settings....

    I tried the "BlockJavaExecution" and get an alert windows when use it...

    With "BlockTeamViewerProcesses" enabled, OSArmor block TeamViewer, but it doesn't show any alert window.

    Why wouldn't you? Malware might force shutdown and when you boot again you're screwed. Checking the box doesn't prevent you from being able to shutdown computer the normal way (i.e. alt + F4).

    Sometimes, OSA starts with protection disabled on boot. I try to enable protection but it won't. This down below is the only OSA-process running. The OSA service is not running on boot. This happens in around 50% of the boots. Known issue? I'm on Win 10 x64 and Windows Defender for protection along with NVT SysHardener and OSA.

    I am using Eset Internet Security and so far it has not become disabled. But, in the past it would take a few days for it to start happening so we shall see.

    Win 10 home 1709x64 running as Admin
    EAM
    AdGuard
    Glasswire
    SysHardener
    Heimdal

    Edit: Enabled after reboot

    I had assumed this could be some interaction with EAM, as Peter2150 and I have experienced this.

    But then shadek #1286 does not have EAM ...

    I have been running with this set up apart from SysHardener (which I installed when it was first released) for over a year and have been running OSArmor since build 3 and this is the first sign of any problems so maybe there was an EAM update that has caused the blip. Will see when I switch on tomorrow.

    @Sampei Nihira

    Great :)

    @bjm_

    That FP will be fixed in next build.

    @shadek @Antarctica @Trooper @Dark Star 72 @Charyb @IvoShoen

    We're investigating the "protection is disabled at startup" issues on OSA.

    I found an useful article that may be related to OSA issues:

    https://www.codetwo.com/kb/how-to-extend-the-timeout-for-services-if-they-do-fail-to-start/

    I would like to ask you guys if you can make two tests:

    Test 1 - Set OSArmorDevSvc to "Automatic (Delayed Start)"

    Set the "Startup Type" of OSArmorDevSvc to "Automatic (Delayed Start)".

    Then reboot the PC and see if the issue is gone.

    * Test a few reboots, just to be sure *

    Test 2 - Tweak Windows Registry value ServicesPipeTimeout

    Add or edit the ServicesPipeTimeout registry value on HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control:

    Go to Start > Run > and type regedit.
    Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
    With the control folder selected, right-click in the pane on the right and select new DWORD Value.
    Name the new DWORD: ServicesPipeTimeout.
    Right-click ServicesPipeTimeout, and then click Modify.
    Click Decimal, type '180000', and then click OK.
    Restart the computer.

    That would increase the timeout for "ServicesPipeTimeout" value.

    Then reboot the PC and see if the issue is gone.

    * Test a few reboots, just to be sure *

    Let me know the results.

    Hi there - thanks for this amazing tool! I've added it to my "install on every new PC" list. :)
    I've just wanted to mention these alerts - the first one seems to be false, as it popped up after I ran the Flash Beta installer from labs.adobe.com:

    Date/Time: 3/13/2018 9:43:14 PM
    Process: [1876]C:\Windows\SysWOW64\Macromed\Temp\{40C291C1-5489-4B96-8074-FB6F066BB16A}\InstallFlashPlayer.exe

    I'm not sure about this second one. This one appears after every startup on a fresh Asus system:

    Date/Time: 3/13/2018 9:40:37 PM
    Process: [15260]C:\Windows\SysWOW64\WindowsPowerShell\v1.0\powershell.exe

    Command Line: powershell $packages = Get-AppxPackage; $result = @(); foreach ($package in $packages) { try { $manifest = Get-AppxPackageManifest $package; $applications = @(); foreach ($app in $manifest.Package.Applications.childNodes) { if ($app.Id) { $applications += @{ Id=$app.Id; StartPage=$app.StartPage; DisplayName=$app.Properties.DisplayName; Description=$app.Properties.Description; PublisherDisplayName=$app.Properties.PublisherDisplayName; Logo=$app.Properties.Logo; OSMinVersion=$app.Prerequisites.OSMinVersion; OSMaxVersionTested=$app.Prerequisites.OSMaxVersionTested; }; }; }; Add-Member -InputObject $package -NotePropertyName "Applications" -NotePropertyValue $applications; $result += $package; } catch {}; }; ConvertTo-JSON $result -depth 10;

    The second one looks safe to me

    I'm often wrangling with this machine at startup and due to problematic hardware, the Internet connection isn't always established when it boots. At times, I discover by accident that OSArmor isn't enabled. Is there any consideration for some sort of notification to tell you OSArmor is disabled? When you've disabled it yourself without the timer also, you can forget these things if you're busy. Is making its startup Automatic-Delayed feasible?

    The tray icon changes colour when protection is disabled.

    Yes, I know, but I've hidden the taskbar. OK, just wondering. I'll have to keep an eye on it then.

    @Antarctica

    Great, thanks for testing.

    @Lorina

    Glad you like our software :)

    The 2 alerts you reported seem to be safe, I will fix them on the next build.

    Thank you for reporting them.

    //Comment about the first alert:

    Would have been awesome if also this Adobe Flash executable file could be signed by Adobe Systems Incorporated:

    Code:
    Process: [1876]C:\Windows\SysWOW64\Macromed\Temp\{40C291C1-5489-4B96-8074-FB6F066BB16A}\InstallFlashPlayer.exe
    Signer:
    
    Unfortunately it is not.

    @plat1098

    We can discuss about adding additional popups to remind you the protection is disabled.

    I wrote that in the "todo" list so we'll see.

    Got these in the log today after enabling Block execution of netsh.exe on the advanced settings. Most likely a false positive from Heimdal Pro.
