i cannot open any other program besides internet explorer. i cannot even open pictures. when i delete files, it asks if i want to delete it permanently, it does not even go to the recycle bin. i can't even edit the settings of my taskbar, or even the folder options. i tried installing hijackthis but then it would only say "installation directory must be on a local hard drive" even tried using rkill, when i run it, it says "there was a problem retrieving a necessasry environment variable: appdata. rkill has terminated" then i used mbab. and scanned my computer and removed the threats, and yet i cannot open anything. need help. thanks.
