Sorry, don't know your name. I would like to have more explicit info & then will try to say something (hopefully) helpful.
Of course, I don't always recommend clean installs over upgrades but, that's pretty much water over the dam now.
When you say, "can't access internet via IE" Do you mean you have IE but, won't load websites OR that you can't find IE in the machine @ all? Makes a big difference as to what directions I go in replying.
As for iTunes, remove it, if it's in the P&F list... either way..re-install iTunes.
Thanks
Drew
