Windows 7: Cannot turn WIndows Update on

and where do those options appear?

In the Boot menu, which is accessed by pressing F12.
I also made a CD with the sweeper tool, and while it boots, the program fails to start:
"Microsoft Standalone System Sweeper cannot be started. Please contact support. Error code: 0x8004cc05".

That means you did not perfectly follow the directions I gave.

Start over and this time follow each and every step precisely.

I was able to get the CD to work. I had to disable the floppy drive (which I don't even have) on the BIOS and Device Manager.
The Sweeper found one virus, and now Windows Update is ON, but when I open it, I see a blank, unresponsive window.

Yonyz,


The results of System Sweeper will be in:
\Windows\Standalone System Sweeper\Support as one or more files with a LOG extension.

Attach those files to your next post please.

The file infected is dvm.dll, which belongs to the game Chronicles of Riddick: Assault on Dark Athena (it's a cracked file, which could be the reason the Sweeper thinks it's a virus).

The themes are by Hyperdesk this particular one is called DarkMatter Subspace.

Hyperdesk: The ultimate desktop themes for Windows 7, Windows Vista, Windows XP, skins, icons, wallpapers, widgets, desktop themes for Disney, Pixar and Star Trek, themes for the PlayStation 3, PlayStation Portable and more!

I do change themes quite regular using third party themes from Mr. Grim and others as well which take a little bit of install knowledge if your into that stuff..as for that cracked file are you not able to get rid of it?

Threat Name:VirTool:Win32/Obfuscator.XZ
came 'packed' with Program Files (x86)\GOG.com\Beyond Good and Evil\gogwrap.exe->(UPX)

No, that BGE file is not cracked. It's a Good Old Games package. No way they would put a virus inside it.
The infected cracked file is called dvm.dll, and belongs to the Riddick game. And I did quarantine the file, but now Windows Update is off again.

Honestly, I don't think it's a virus. My brother messed with the networking services a few weeks ago, trying to get sharing to work between two Windows 7 computers, though he didn't succeed at that.

run the system file checker.
SFC /SCANNOW Command - System File Checker

Believe us. The file is infected.
