I've noticed something wrong with my PC over the last year or so. Every time I update something (Java, iTunes, Chrome, etc.) things act up pretty badly. For example, if I update any of those things, my internet would act up. By that I mean certain pages won't load (I'd have to refresh once or twice), there would be random toolbars/plugins I didn't even ask for in my browser, anything that I stream (YouTube, pandora, etc) will stop loading randomly or buffer very slowly (it's not my internet speed that's the problem), and sometimes iTunes won't recognize my iPhone that is linked to it, giving me unknown errors. The only solution I've been using is System Restoring my PC to an earlier point to where it was working properly (it would have to downgrade my iTunes, chrome, etc.) The thing is, I need these things updated at this point, I can't have them downgraded anymore. Does anyone know why my computer does this to me every time I update anything? Any help will be immensely appreciated.
