firefox.exe running in the background whenever I open Firefox, high CPU consumtion

Hi,

Whenever we open Firefox, there is a firefox.exe running the background that CANNOT be stoped no matter what we do. We are using ADMINISTRATOR account with elevated privileges, but if we try to close it, it simply doesn't react at all. Sometimes it even states that we do cannot perform the action. It consumes high CPU and sometimes it even crashes the browser, and whenever we restart it, the process "pops ups" again.

We have done the following checks: - Scan the Server with multiple anti-viruses: no viruses to be found. - Disabled the plugins: no luck in doing that - Uninstalling and reinstalling Firefox: the process is still there

Any help Will be much appreciate it.

Hi dmartinezn, I'm puzzled that there are so many different user names listed. Are these all legitimate Firefox users?

How recently did this problem start?

Could you use Microsoft's Process Explorer tool to check whether any of your firefox.exe processes are being launched by other programs?
