At many sites on my PC, HP w/Win 7 Home Premium, 64 bit, IE9, I am unable to access and receive this message: "You may not have the appropriate permissions to access the item".
I am not PC literate and have no idea what this means and how to correct it.
Any help would be appreciated. Thank You.

Are you the only user on your machine?

Yes, I am the only user on this PC. The probhlem continues. I had d/l a free registry cleaner, ID Vault, and started to experience problems then. It tooki a bit to get rid of it as it would not let me uninstall. But, I believe I was able to get ri8d of it, I think. But, the problems continue.
Help. Thanhks.
