Microsoft Office SDX helper- High CPU in background

Anonymous

Today while I was doing work my computer fans started whirring for seemingly no reason- all I had open was google chrome. I checked task manager and found on program, Microsoft Office SDX helper, was using large (as in 70%) CPU out of the blue. Worried that it would crash my computer, I hit end process and nothing happened, so I thought I had solved the problem. However, this evening went I went to do more work the same issue happened, and again SDX was the culprit. And now it just happened a third time.

I can't imagine what is causing it to do this. I had not opened any office programs since I last restarted the computer and it has not happened before today. For a short term fix, I uninstalled Office for my sanity and not needing to keep the task manager tab open all day. Does anyone know of this problem/how to fix this?

I solved the same problem, first open programs and features, select Microsoft office, then select change button and automatically office repair tool appear, select deep repair, it reinstall's office, and the problem is solved.

    I think SDXHelper.exe  is a spyware when MS Office is not running

    Just rename the exe file of your choice.

    I did

    sdxhelper.exe to sdxhelper1.exe

    I simply did this and never saw this app in the background.

    I tried this and it worked for two days.  Then Microsoft Office SDX helper was back, burning up my CPU.  How can I kill that miserable piece of cyber-junk permanently?  That's what I'd like to know.

    No, it does NOT solve the problem.  I did exactly that and Microsoft Office SDX helper was back chewing up my CPU two days later.
