How to Remove “ShellExecuteEx failed; code 5. Access Denied” Malware?

I cant access programs as "You may not have the appropriate permissions to access". I think I'm infected. I am running Window 7. I've tried installing Malwarebytes to check for malware and I get the "ShellExecuteEx failed; code 5. Access Denied" error come up.

I've tried right clicking it and running as administrator and then I get the " You can not access the specific device, path or file. You may not have the appropriate permissions to access the item" message.

I have also noticed I now have the hao123 site as my home page and I did not set this up...

Once you get this message, it seems that you don't have the permissions to run the programs. You should deal with it by creating a new user account as Administrator account.
