The registry contains settings for low-level operating system components as well as the applications running on the platform: the kernel, device drivers, services, SAM, user interface and opulent third party applications all make employ of the Registry.

Some viruses, however, disable system restore and other important tools such as Task Manager and Command Prompt. An example of a virus that does this is CiaDoor. The computer Registry Keys are similar to folders – in addition to values, each key sometimes contains subkeys, which may contain further subkeys.
The registry also provides a fashion to access counters for profiling system performance statistics. The Windows Computer Registry is an important configuration database that holds and stores settings and options on Microsoft Windows operating systems.
One method is to employ a heuristic algorithm to locate viruses based on common behavior traits. The disadvantage of some detection methods is that users are only protected from viruses that pre-date the last virus definition update.
Many users install anti-virus software that can detect and eliminate known viruses after the computer downloads or runs the executable. A virus attempts to modify the registry, except, when the Administrator is controlling the computer, it blocks all users from accessing the tools.
Reinstalling the operating system is another approach to virus removal. Once a computer has been compromised by a virus, it is usually unsafe to continue using the same computer without completely reinstalling the operating system especially if the computer lives on a shared network.
Often a virus will cause a system to hang, and a subsequent hard reboot will render a system restore point from the same day corrupt. Anti-virus software also needs to be regularly updated in order to prevent the latest threats from infecting the PC.
The on-disc structure of the registry is entirely unique on the NT line of Operating Systems (including Windows XP and Vista) than Windows 9x series OS, slowdown due to registry bloat or Rot now occurs much less frequently.
With regular back ups, if data is lost through a virus, one can start again using the backup (which should preferably be as recent as doable). Restore points from recent days should work provided the virus is not considered to corrupt the restore files or also exists in previous restore points.
One may also minimize the damage completed by viruses by making regular backups of data (and the operating systems) on specific media, that are either kept unconnected to the system (most of the time), read-only or not accessible for other reasons, such as using distinct file systems.
