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
Do not have this app on your computer, delete it immediately!! Especially with Windows 7. Restart and watch the immediate improvement without it !
it starts running hundreds of qttask.exe processes and i dont know what to do. uses 100% cpu, im barely able to make my computer function
I'm concerned because it is located in a Run- folder not the Run folder

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 cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the QTTask.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
