No taskbar, Internet access, can't run programs, and other problems

Thank you in advance for helping with this!

Desktop looks normal except that there's no taskbar (just a thin grey bar across the entire bottom of screen; and CTRL + ESC doesn't work). IE won't open but Firefox will, but no Internet access because of the virus. I can open Task Manager (CTRL + ALT + DEL) and run Explorer or Command, etc. and have been able to install AVG, HijackThis, Malwarebytes.

Malwarebytes installed but got this error during installation and when I run it: Run-time error '372': Failed ot load control 'vbalGrid' from vbalgrid6.ocx.

AVG installed without any error messages but won't run.

Here's what I've done so far from your list of "must do this before posting":
1. ATF cleaner ran successfully
2. Can't get on the Net to run Kaspersky WebScanner
3. Can't get on the Net to get any Windows updates
4. Have rebooted many times in the course of working on this
5. HijackThis log is posted below
