Sek,
Just to be safe, I would recommend to do a full scan of your system with Malwarebytes free (if not the one you already have) to see if it finds anything.
You might also run a sfc /scannow command to see if it may be able to find and fix any bad system files that may be responsible.
I'm afraid that I don't know amything about iTunes other than a lot of people have issues with it.
