Firefox will open in the background and I do not know it. It is only when I notice how slow my computer is running that I check the Windows Task Manager and notice Firefox running when I never went to the internet all day. I ran Kasperski and it doe not find a virus. I believe the problem is a file named cloudctl.xex*32. when I close that file it stops Firefox from opening in the background. Any incite on how to repair this problem? Attached is a link to the problem with no fix. https://support.mozilla.org/en-US/questions/1213921 I deleted Firefox and ran chrome and windows Internet explorer. Both had the same issue. thank you dave P.
