HP Pavilion dv9000 notebook
Vista
used at office on network

I was searching on Google Video using the new Google Chrome browser.
Search was LIMITED to "videos playable on Google".
I got a drop-down on the browser stating that I needed to install Quicktime plug-in, which I proceeded to do.
After a few minutes of download, the Chrome browser froze, and would not close using Task Manager.
Tried a restart....desktop came up EMPTY except for recycle bin and desktop.ini
No programs show under the start menu.  Almost EVERYTHING in My Documents has disappeared.
Windows explorer still shows some program files, but others are missing.
Windows Defender will not start.
Windows Restore shows no restore points available.
Could not access my computer thru the Symantec Client software on the network server


I've downloaded and run the following:
AntiVir Personal...nothing detected
Nothing unusual in Add/Remove programs
CCleaner Slim...nothing unusual
SuperAntispyware...nothing detected
Malwarebytes Anti-Malware...see attached log
Tried to update with latest Java...kept getting message that it could not access network resource.  Removed old versions using JavaRA
HijackThis...see attached log


Thank you for your HELP
