Windows Defender Issue

Hi,

I'm getting the attached message when opening linqpad, and it is almost certainly related to Windows Defender and real time threat protection. (https://us.v-cdn.net/5019392/uploads/editor/bb/o68ui3i7o5y8.jpg "")

I am definitely seeing timeouts and odd behavior on occasion. Do you have any whitelisting or other strategies that can help mitigate anti-virus software getting in the way?

Thanks,
Ryan

  • There are a couple of things you can try. The first is to disable cloud-delivered protection under "Virus & threat protection settings". There appears to be a bug in Windows Defender's cloud-delivered protection that sometimes causes it to go overboard in choosing which files to submit for online analysis. This is an intermittent bug that comes and goes, sometimes causing a problem for several days/weeks before disappearing. It can also affect build and run times in Visual Studio.

    The second is to whitelist LINQPad. You will need to whitelist the following executables:

    LINQPad7.exe
    LINQPad7-x64.exe
    LINQPad7.Query.exe

    You should also check that there is no other antimalware software on the machine.

    Let me know how you get on.

  • Thanks for the information Joe. The cloud-delivered protection issue sounds quite similar to what I'm experiencing. Unfortunately I don't have rights to disable that feature on this machine. I have been able to get those executables whitelisted.

  • Love linqpad by the way, use it constantly
