i get this error message when i open itunes and then it comes up frequently while itunes is open. itunes will still work properly but it keeps me from being able to sync my ipod.

I can tell you thats a driver.
Go into search
Type device manager
In device manager look for any small yellow warning markers (especially around graphics)
Make sure drivers are up to date.
This driver is commonly used in most programs. It is a prime target for malware writers
Run a full anti virus scan
Download and run malwarebytes, full scan and updated.
Make sure that Windows Automatic Update is turned on and allowed to accept drivers.
