i never said it keeps comming back!! i just CAN'T delete the files
Sorry, I've misunderstood.
Maybe the only possibility is running chkdsk (check disk) at boot time.
Go to My Computer, choose the partition (C:\) where the file is, choose Properties and then on the window that opens, click on Tools.
Check the disk and ask for all options of fixing.
Most probably you'll be asked to 'schedule' this running on the new boot. Accept it.
Boot.
