Virus attack which disabled Regedit and Task Manager

Hey all:

Today I felt mysterious to see that the task manager in my machine was disabled & When i tried to run Regedit, an alert was shown saying the user does not have administrative privilege to run this program. Then i ran Anti virus scanning through AVG to get rid of the viruses & found the following steps to enable Task Manger & Regedit from Yahoo Answers...

All these options can be restored through the Group Policy management console.
In order to enable them, please follow the steps below:

1. Open C:\Windows\system32\gpedit.msc

2. In the Group Policy window go to the path:

Local Computer Policy >> User Configuration >> Administrative Templates

3. Find the following entries and perform the necessary adjustments:

- To enable Folder Options:

- Go to Windows Components >> Windows Explorer
- Double-click Removes the Folder Options menu item from the Tools menu
- Select Disabled and confirm with OK

- To enable Task Manager:

- Go to System >> Ctrl+Alt+Del Options
- Double-click Remove Task Manager
- Select Disabled and confirm with OK

- To enable Command Prompt and Regedit:

- Go to System
- Double-click Prevent access to the command prompt
- Select Disabled and confirm with OK
- Double-click Prevent access to registry editing tools
- Select Disabled and confirm with OK

4. Close Group Policy

Hope this should be helpful for people who went puzzled like me :)
