I start Windows 10 and soon after startup there will be an item listed in the Apps section of Task Manager: "Firefox.exe (32 bit)". This will have a Firefox icon next to it.

I have never installed any version of Firefox. While "Firefox" is running any other program that I open will stop running after a few seconds.

I can stop "Firefox" using End Task and then everything works just fine.

I am wondering if this is caused by a virus or some other type of malware?

A built-in thing you might check: In the Windows 10 Task Manager, switch to the Details tab and add the "Command Line" column. This can be very wide. It should show where Firefox is located on the system and possibly whether it is being pointed toward a particular URL.

Tried this and found 1 program using the firefox icon called 'update.exe' see images below of task manager in 'Details' and 'Processes' views'

Ok. I have now solved this. I first disabled 'update.exe' in 'Startup' tab of task manager and then I deleted the entire folder that it was in. After rebooting there is no problem now. Thank you jscher2000 for the command line tip as it led me to where I could and eliminate the problem.

Also, I have tried searching on the internet and through several pages of results on Google and Bing can find nothing relevant to this problem.

Hi, End Task then please search and see if it is installed in Programs and Features applet of your Win10. If so please uninstall it. While there please look for anything else that should not be in the list of installed programs and remove them.

Then please use more than 1 scanner as each uses diff tech :

Save your Report and google each before deleting anything as do not want to delete something you need, If need help :

Post in only 1 forum, then wait.

Please let us know if this solved your issue or if need further assistance.

I have never installed Firefox. It is not listed in 'Programs and Features'

I understand you say you never installed it. Did you check Programs and Features though ? If so and not there please move to the 2nd part and do a scan.

A screen shot would be useful of the icon you say is Firefox.

What part of "It is not listed in 'Programs and Features'" do you not understand?

Here is an image of task manager and the 'F' and 'M' sections of 'Programs and Features'.

"Firefox.exe (32 bit)"

This should have read "Firefox (32 bit)"

Could you check the normal installation locations to see whether Firefox is there:

  • C:\Program Files\Mozilla Firefox
  • C:\Program Files (x86)\Mozilla Firefox

This Microsoft program shows a different view of running programs -- it may help connect Firefox running as a child process of another program with its master:

A built-in thing you might check:

In the Windows 10 Task Manager, switch to the Details tab and add the "Command Line" column. This can be very wide. It should show where Firefox is located on the system and possibly whether it is being pointed toward a particular URL.

Neither of these folders exist on my system

So you have Portable Firefox then. https://portableapps.com/apps/internet/firefox_portable

I seemed to have part of it. There was no executable (.EXE) file to actually start Firefox portable. There were only 2 .EXE files; update.exe and crashrepoter.exe. Crashreporter may have had an underscore or hyphen in it. At the time writing this I am working from memory as I deleted the Firefox Portable directory from my system and the problem is solved.

Keep in mind also that I never put this on my system.

Nor would the standard Firefox installer use that location.

Maybe some other program was using those files for its own purposes. A troubling prospect.

If there was I do not know what it would be and was never asked by any installer if these files could be put on my system. I have removed the entire Firefox Portable folder and nothing seems to be affected.

I agree.
