Cannot Rename folder or install new programs (userappdata error)

[cathay]

Hi,

I came back from a trip and my computer is acting up. So far, I've found at least 3 different problems I never had before.

1) Create new folder. Then right-click to Rename it. Type it desired name and pressed Enter. Name reverts back to "New Folder". Have full access (administrator) and took control over folder and the top level folder also. Never had this happened before.

2) Downloaded new programs - go through installation process. When it is trying to install, it reads "Internal Error: failed to expand shell folder constant "userappdata""

3) I am running Avast Anti-virus. Did all new updates. When finished running, there are many files and folders that are "password" protected so therefore Avast is not able to access those files. I never set passwords to my files and this has never happened before.

4) I noticed there was an "Unknown User" that is showing up in some of my folder property when I was checking access rights.

Here is a log from Hackjackthis...please help!!!
