Hi, Yes, you are right !, your system is infected with a serious virus and you cannot use your computer unless you remove the visus.
This problem happens when there is no updated antivirus running.
To fix it, download/ aquire MacAfee antivirus and its latest update.
Boot the system to safe mode, and install the macAfee and update. Run the scanner and remove the virus.
Try and let me know if its not succeeded.

thank you

Tip

Enable the Registry Editor, Task Manager and Folder Options Disabled by Viru


Virus attack is common these days and we often come across the problems like Disabled Folder Options or like Task Manager and Regedit disabled by Administrator. These problems are nothing but virus activities. The virus has infected our system and stopping us from accessing these options.

Pressing keys Ctrl+Alt+Del opens up a dialog saying that “Task Manager has been disabled by your Administrator” whereas you are the Administrator yourself. It becomes very annoying when you think that you can fix this problem by going into the Registry Editor but it doesn’t show up. Even the Folder Options gets disabled.
This problem is generally caused by a virus named “Brontok” but don’t worry just use RRT (Remove Restrictions Tool) that can easily solve this problem. RRT is free and can successfully enable:
1. Folder Options
2. Regedit (Registry Editor)
3. Task Manager
4. Show Hidden Files option
The tool will come more useful if you use it in Safe Mode.
Download RRT

My task manager has been disabled due to virus attack. help me


There is a registry hack to enable or disable Windows NT TaskManager. The same registry hack applies to Windows 2000 and Windows XP. Hive: HKEY_CURRENT_USER
Key: Software\Microsoft\Windows\CurrentVersion\Policies\System
Name: DisableTaskMgr
Type: REG_DWORD
Value: 1=Enablethis key, that is DISABLE TaskManager
Value: 0=Disablethis key, that is Don't Disable, Enable TaskManager

As part of the enhanced management available in Windows 2000 and Windows XP, rather than risking a registry change, as an administrator you can enable or disable Windows 2000 Pro or Windows XP Pro's TaskManager using Group Policy Editor. This can be applied to the local policy. Note: if you are trying to override your organizations group policy, you can't. As soon as you re-authenticate to the domain, the domain or OU Group Policy will rewrite the registry setting. But if the TaskManager was accidently disabled or you need to control this item for a set of standalone boxes this is for you:
  • Click Start
  • Click Run
  • Enter gpedit.msc in the Open box and click OK
  • In the Group Policy settings window
    • Select User Configuration
    • Select Administrative Templates
    • Select System
    • Select Ctrl+Alt+Delete options
    • Select Remove Task Manager
    • Double-click the Remove Task Manager option
And as I mentioned above, since the policy is Remove Task Manager, by disabling the policy, you are enabling the Task Manager.

I am very much impressed by ur suggestion on my task manager problem.


So the task manager is now working.

if you want todo the same thing for regedit then you need to copy this text into the run menu and press ok

REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /t REG_DWORD /d 0 /f

That should get the registry editor working again.
