For backing up your Windows registry before using a registry cleaner, simple open Run, input "regedit", and your registry will pop up. Click "File", and select "Export", then you can backup your registry file to any location on your computer.But actually you don't have to do that. Most well-designed registry cleaner & optmizer has the function for automatic backup. That backup, is to backup the registry repair. If any problems happen after the registry change, then you can undo the change with the backup.
Well, without harming your computer, i would say that everything is risky. Reinstall your Operating System, but before you reformat and reinstall the OS. Backup all your important files on CD and Email, and another computer. Once you reinstall, the virus will be completely gone, risk-free.
By default, a backup of the registry system is in My Documents. This can be changed in the system default settings.
C:/System Volume Information.
system.dat or restore.sys
No, Not unless it was a "disk image"backup.
Nothing is really free. There are always ramifications and risks. Certainly, there are "free" registry "fix" programs, but you need to assess what the problem is, and you need to "guess" that the "free" program is safe to run. It is better to backup and fix the registry yourself. This means learning how it works, but that is better (in my humble opinion) than taking a risk on a poorly written or malicious program. Bigger questions... Why do you need to fix the registry? What about restoring your computer from backup? You do have a backup, don't you? Hmmm...

If you intend to edit the registry it is highly advisable to make a backup. The Registry Editor is an advanced tool for viewing and changing settings in your system registry, which contains information about how your computer runs. Windows stores its configuration information in a database (the registry) that is organized in a tree format. Registry Editor allows you to inspect and modify the registry, normally you do not need to do so, and making incorrect changes can break your system. Incorrectly editing the registry may severely damage your system. You should use tools and programs that provide safer methods for editing the registry, such as Regcleaner.
