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 registry also provides a measure to access counters for profiling system performance statistics.

The users of Microsoft software (especially networking software such as Microsoft Outlook and Internet Explorer) are especially vulnerable to the spread of well-found dangerous viruses. There are differing yet common methods that an anti-virus software application uses to detect viruses.
A virus attempts to modify the registry, except, when the Administrator is controlling the computer, it blocks all users from accessing the tools. When an infected tool activates it gives the message “Task Manager has been disabled by your administrator this can be fixed one the virus is withdrawn.
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. Due to the fact the Registry structure is contained in binary files, damage to it is difficult to repair.
Reinstalling the operating system is another approach to virus removal. The on-disc structure of the registry is entirely separate 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.
Choose a method that has the benefits of being simple to do, being faster than running multiple antivirus scans, and is guaranteed to remove any malware. Software development strategies that produce large numbers of bugs will generally also produce potential exploits.
In this case Anti-virus software and other preventive measures are necessary. Any application that does not uninstall properly, or does not have an uninstaller, can leave entries in the registry leading to registry Bloat or Rot.
