my windows security just blocked cltLMH.exe does anyone know what it is? it seems like my windows security blocks cltLMH.exe everytime my computer needs to update.

Hi, my name is Nigel and I am an Independent Advisor for Microsoft here to try and work with you on this issue you are having.

This file is part of Symantec Shared Components. CLTLMH.EXE is developed by Symantec Corporation.

First question is do you have any Symantec software running on your machine?


Hope this helps!

Hello.

I would uninstall both Norton Security (Which is owned by Symantec) and Malwarebytes. There are issues with compatibility with Malwarebytes and the latest Windows 10 update.

The best way to remove Norton completely is using the following tool.

Windows Defender is sufficient to protect against Virus and Ransomware.

Thanks

Hello,

If the Norton has expired, just uninstalling that using the tool will be sufficient.
For now lets keep Malwarebytes and retest again

Thanks
