Windows 10: HELP! Windows Security Message - "Enterprise unwanted application found. This application...

BruceBrecht · Oct 6, 2021

This is my personal desktop running Windows 10 Pro latest version as of today.Some apps I look to install get this message and the install fails. I had some work applications on here previously but have removed them and the work account form my PC as well.Is this message caused by some left over security feature from an enterprise security feature that I can locate and remove? I don't see any remanants of the work account or applications and would like to stop this from happening. Any help is appreciated.

Windows fails to open applications

Hi,

Once I have several applications open Windows XP Professional Service Pack 2 refuses to open further application. I have heavy-weight applications like Delphi and Eclipse open, but the OS has coped with this in the past.

No error messages are reported by the application I am attempting to open, and there are no messages in the event viewer. What is really strange is that once the OS gets itself into this state, it appears that the OS can't allocate enough memory to perform simple API calls. If I go into an application that is already open and try to open the file menu, or right click on the taskbar to open the context menu, nothing happens.

If I close a few applications, then the problem goes away. The Task Manager performance tab indicates that I still have ~1Gb of physical memory available.

I think this could be caused by:

- A memory module is damaged. My memory is comprised of 1x1Gb modules. When the system attempts to allocate memory in the second module, it is unable to. I think this is a bit of a long-shot because I wouldn't expect my PC to boot if a memory module was playing-up

- I've installed something that has put something malicious on my PC. The only things I've installed recently are PRGrep and WinGrep, but unfortunately I didn't make a system restore point, and windows hasn't retained those old restore points. However a full Sophos scan doesn't show-up anything.

Any suggestions on how to diagnose/fix this welcome because I'm baffled as to what is going on.

Thanks,

Frank.

Good Applications/Utilities

What are some good applications/utilities that would help my computer in any way. That includes speed, performance, security - anything. Even simple things that you occasionally need, for example, a video encoder or even benchmark programs...just anything *Big Grin

Check my recommended programs thread. But I haven't updated it in a while but it's still a good list.

Windows Defender Application Guard extensions for Chrome and Firefox

The hardware-based isolation technology on Windows 10 that allows Microsoft Edge to isolate browser-based attacks is now available as a browser extension for Google Chrome and Mozilla Firefox.

We introduced the container technology in 2017. Since then, we have been evolving the technology and engaging with customers to understand how hardware-based isolation can best help solve their security concerns. We know that many of our customers depend on multi-browser environments to allow enterprise apps to meet various compatibility requirements and enable productivity. And while modern browsers are continuously working to mitigate vulnerabilities, there are still exposures across these complex engines that can lead to irreversible and costly damages.

To provide customers with a comprehensive solution to isolate potential browser-based attacks, we have designed and developed Windows Defender Application Guard extensions, now generally available, to allow customers to integrate hardware-based isolation with Google Chrome and Mozilla Firefox.

How it works

The extensions for Google Chrome and Mozilla Firefox automatically redirect untrusted navigations to Windows Defender Application Guard for Microsoft Edge. The extension relies on a native application that we’ve built to support the communication between the browser and the device’s Application Guard settings.

When users navigate to a site, the extension checks the URL against a list of enterprise sites defined by enterprise administrators. If the site is determined to be untrusted, the user is redirected to an isolated Microsoft Edge session. In the isolated Microsoft Edge session, the user can freely navigate to any site that has not been explicitly defined as enterprise-trusted by their organization without any risk to the rest of system. With our upcoming dynamic switching capability, if the user tries to go to an enterprise site while in an isolated Microsoft Edge session, the user is taken back to the default browser.

To configure the Application Guard extension under managed mode, enterprise administrators can follow these recommended steps:

Ensure devices meet requirements.

Turn on Windows Defender Application Guard.

Define the network isolation settings to ensure a set of enterprise sites is in place.

Install the new Windows Defender Application Guard companion application from the Microsoft Store.

Install the extension for Google Chrome or Mozilla Firefox browsers provided by Microsoft.

Restart the device.

Intuitive user experience

We designed the user interface to be transparent to users about Windows Defender Application Guard being installed on their devices and what it does. We want to ensure that users are fully aware that their untrusted navigations will be isolated and why.

When users initially open Google Chrome or Mozilla Firefox after the extension is deployed and configured properly, they will see a Windows Defender Application Guard landing page.

If there are any problems with the configuration, users will get instructions for resolving any configuration errors.

Users can initiate an Application Guard session without entering a URL or clicking on a link by clicking the extension icon on the menu bar of the browser.

Commitment to keep enterprise users and data safe

Hardware-based isolation is one of the innovations that enhance platform security on Windows 10. It is a critical component of the attack surface reduction capabilities in Microsoft Defender Advanced Threat Protection (Microsoft Defender ATP) and the broader unified security in Microsoft Threat Protection. With the new Application Guard extension for Google Chrome and Mozilla Firefox, customers can extend the security benefits of isolation in their environments and further reduce attack surface. Customers can confidently navigate the expansive internet with protection for enterprise and personal data.

The Windows Defender Application Guard extensions for Google Chrome and Mozilla Firefox are now available for Windows 10 Professional, Enterprise, and Education SKUs, version 1803 and later with latest updates.
