I can't reinstall firefox, I get the "profile cannot be loaded" error and no solution I've found works. The /appdata/roaming/mozilla folder is inaccessible.

I'm on Win7, 64 bit. I originally uninstalled because a program changed my new tab page to something unwanted and I had literally no way of changing it back. Now every time I reinstall it I get the "profile cannot be loaded, it may be missing or inaccesible" error, and I cannot create a new profile. Every time I try any method of opening the profile editor, I get the "profile cannot be loaded" error then too. I can't access the folder under /appdata/roaming/mozilla at all. It says it is inaccesible and access is denied, and trying to delete it tells me that I don't have permission (even though I'm the admin). No other fix I have seen has worked. Can anyone help, please?

I ran a virus scan, cleaned up a single piece of adware, restarted, and it suddenly worked. I'm not sure what exactly caused it to begin working but it did so I consider this matter closed.
