DotNetBrowser.Chromium.exe and Windows Installer running continuously

We have a Windows 10 and 2 days have passed that the PC is super slow.  When checking we see 'DotNetBrowser.Chromium.exe' and 'Windows Installer' running hogging the processing.

How can we know this is an actual download of windows update or malicious code?

We went into control panel to see if we could find something in 'Windows Update' or 'Check for Updates', but could fin anything relating to what's happening.

The original DotNetBrowser.Chromium.exe file is not a Malware.

Note proper Malware removal will need a lot of time, so your patient’s is asked. If this is a corporate environment I strongly recommend to reimage or reinstall your client as nobody can give 100% guarantee that all Malware is removed.

Download Farbar Recovery Scan Tool (FRST) .

Click on the 32-bit version or 64-bit version button. Note it depends on the bit type of your Windows version.

Now run a FRST Scan with the default settings .
Please upload both log's on your next reply.

If you need my help, please do not run any other tools or scanners than what I ask you to.

Do you have Windows 10 Version 1607 (Anniversary Update)?
If yes there is a known problem (the installer can hang). Can you reboot the client, download KB3189866 manually and install it?

should we have  "Windows 10 Version 1607"???
*** Hopeleonie ***IT ManagerCommented:
Windows 10 Version 1607 is the anniversary update. Normally it will take time to update. Did you search for updates?
rayluvsAuthor Commented:
yes we did, here is a pix:

It has been at 0% for a long time without no change

Is this normal?  What can we do?

Also, we downloaded ‘Farbar Recovery Scan Tool (FRST)’ but not ran it because re-reading your entry ID: 41802945 you say ‘strongly recommend to reimage or reinstall your client’.

By running FRST will it possible damage our PC?

Also, your link ‘’, when we click on it it gives the following:

What is this link for? Can you supply another link?

We just uninstalled completely after searching if its important for windows; and it's not.  We assigned the points becuase it's the right direction to go if we needed to stay with the apps and clean it out.

No FRST will never damage your system. FRST will only list Malware infections.

What is this link for? Can you supply another link? will work with IE or Firefox.
