Firefox keeps coming up without my involvement and I find it constantly in Task Manager. I've tried to make other profiles, but it keeps on coming up. I find it in Task Manager. Can you help?
In order to fix the issue, remove the browser from your computer using Add or Remove Programs feature (Control Panel > Uninstall a program) or Revo Uninstaller. Even if it can't uninstall the application normally, it will force it to uninstall by wiping out all traces of its presence from the system. After that, perform a full system scan using your security program or a utility from Software Informer database and download and install the latest version of Firefox from an official source.
Perhaps your system is infected and it launches a hidden browser window. Try scanning your system with Hitman Pro, MalwareBytes and Super Antispyware.
