It makes my pc runs inefficiently.
It Kills Your CPU
  Robert Ward  
is a quicktime application
By removing it from my task tray my windows 7 display immediately turned to normal and prevented all the processes from running at start up that were using my power. Only then was I able to delete it. Could not delete it using control panel as it does not show up on the list given for uninstalling/repairing etc.
it is a hijacker on some computers
it's quicktime, therefore you should get rid of it and use something else.
It is the Quick Time Task and it turns Windows 7 theme to basic

Best practices for resolving qttask issues

A clean and tidy computer is the key requirement for avoiding problems with qttask. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
