Last night I succesfully installed Ubuntu 12.04 64bit, and then I tried to install Mac OSX Theme from this site

But after and after I followed I don't know what's going on terminal, after I installed the last thing, thats gnome tweak tool, I run compiz and I don't know why it's like something going wrong, my Ubuntu bar dissapear, then it's frozen, so I restart my Ubuntu. After the Ubuntu is showing up, all I see is wallaper, do icon, no bar.

I think the way is to recover the Ubuntu system files like new, if you may help me I really appreciate

Now I'm using Ubuntu 12.04 Live CD. It's all I can use, live CD.

And one other thing, I got Windows 7 64bit, and it's full of spyware (Trojan), I want to clean it, but can I clean it from my Ubuntu? , is that any software that could clean Windows viruses or spywares from Ubuntu?

there is many anti-virus for linux which can be used to clean windows viruses and trojans.

You should do clean install because there would be so many files that are changed or created. It would be very quick solution.

I too vote for a clean install and to make sure you know what you are doing each time you issue a "sudo" command in the terminal. – harisibrahimkv May 27 '12 at 6:12

I also would recommend a clean installation because your system files are mainly corrupted . And it's possible to wreck your Ubuntu install with Compiz or GNOME-Tweak alone if you don't use it properly. So this should give you a lesson to not install anything anonymous.

And if you really want to install a Mac Ubuntu Theme, read this. It's much more easier.

But first, do a clean install of Ubuntu. Here are the steps.

  1. Grab a Windows recovery media or installation CD. You should see this on a recovery media and if you have a Installation CD choose the Repair Your Computer option. enter image description here

  2. Open the Command Prompt, then type bootrec /fixmbr into the Command Prompt. enter image description here

  3. Reboot and boot into Windows. If your Windows is full of viruses and you can't even boot into it, try starting your computer in safe mode, or scan your windows drive with the tools that virpara provided.

  4. Go to Start, right click Computer, then select Manage. Then select Disk Management from the sidebar. Image

  5. Right-click your Ubuntu partitions and select "Delete" . Check before you delete!

  6. Then, right-click the partition that is on the Left of the free space. Select "Extend Volume". Go through the Wizard and Finish it. enter image description here

  7. Install Ubuntu the usual way.

  8. Reboot!
