i have tried to reinstall my itunes, but all it says is still,"error" when i start it up.
Urgent help needed,

Answer 1

It appears, then goes again shortly after.
That's more consistent with malware than most other things ... however the AVG Antispyware typically catches that.
Let's check to see if you've got an atypical set of symptoms of a broken QuickTime. (Following up again on that error message that you get when you click on the QuickTime control panel.)
Let's try swapping out your existing QuickTime.
let's try this technique first.
head into your Add/Remove programs. uninstall QuickTime.
Next, we’ll manually remove any leftover program files and folders.
1. On the Start menu, click My Computer (or double-click My Computer on the Desktop).
2. In My Computer, open Local Disk.
3. Open Program Files.
4. Right-click on the QuickTime folder and click Delete from the shortcut menu.
5. Navigate to C:\Windows\system32\.
6. Remove the files QuickTime.qts and QuicktimeVR.qtx.
7. Restart your computer.
next, we'll get a fresh copy of QuickTime into your PC by doing a repair install of itunes.
switch off antivirus and antispyware applications prior to the repair install.
go into Add/Remove and select itunes. click "Change" and then click "Repair".
if the repair install goes through okay, restart the PC and try launching QuickTime again. does it launch properly now?
If the QuickTime is launching properly, is iTunes launching too now?
