PC unusable after entering iTunes Store.

Hi! I am running Win8 and the lastest version of iTunes. A couple weeks ago everything was fine but now when I want to enter iTunes Store on iTunes, my PC goes so slow it is unusable. It takes about 5 mins to load the iTunes Store and the CPU & HDD usage goes to 100% even when I manage to close iTunes.

I haven't installed anything new in the past month or so.

I have tried the NETSH WINSOCK RESET command but it didn't worked. The problem is also present even if I start Windows in Safe Mode, and/or iTunes in Safe Mode.

I have uninstalled everything related to Apple on my PC using Revo Uninstaller. But I can't enter the iTunes Store anyways...

I can't figure why the problem appeared. If anyone know something that can help It would be very cool! 😎

Thanks in advance!
