First of all open up the command prompt. For that go Start Run cmd.
Now press CTRL + ALT + DELETE to bring up the task manager.
In the task manager, go to processes and click on explorer.exe.
End the “explorer.exe” task.
All the windows will be closed down.
Don’t panic. You can still see the command prompt. In the
command prompt type the following command exactly as it is:
Del "C:\Documents and Settings\\Local Settings\Temporary

Note is the name that you use to log in to your windows. Some
log in as “administrator” while some with another name eg: Sandeep.
Whatever it is, type that name. This will also help in fixing all the issues related to browser
performance, especially the ones that cause browser to hang frequently.

Microsoft has made available a program to analyze and decrease the time it takes to boot to WindowsXP
The program is called BootVis
Uncompress the file.
Run BOOTVIS.EXE
For a starting point, run Trace / Next Boot + Driver Delays
This will reboot your computer and provide a benchmark
After the reboot, BootVis will take a minute or two to show graphs of your system startup.
Note how much time it takes for your system to load (click on the red vertical line)
Then run Trace / Optimize System
Re-Run the Next Boot + Drive Delays
Note how much the time has decreased
Mine went from approximately 33 to 25 seconds.

Domain Pigeon Is a software program through which you can search for available Domain names and the available twitter names.
As there are a lot of domain bieng booked daily, so its getting worst for gettin a unique name which is available.
The same goes for Twitter as its usage is increasing day by day as well.
On Twitter New accounts are being created every day, not to mention the millions of unique visitors of the site each month. It means Twitter account is becoming a valuable web real estate. A website or a blog post being retweeted on Twitter can have the same effect as being on the first page of the popular social voting site, Digg.
So if you are plannig to start twittering with a unique name, or you are finding a unique name for your domain, you must at least once go looking for Domain Pigeon.
I hopes it would help you a lot.
Any queries or suggestions , Please do write as comments.

Gmail has an option to integrate multiple email accounts (email addresses) into a single Gmail account. Once you integrate multiple email addresses into your Gmail account, you can use the same account to send emails from different addresses and receive emails for different addresses. Let’s take a simple example
Suppose you have three email addressess (email accounts)
1. gohacking@gmail.com
2. gohacking@yahoo.com
3. hacker@hotmail.com
You can integrate the emails gohacking@yahoo.com and hacker@hotmail.com to gohacking@gmail.com and operate all the three accounts from your single gmail account. Here is a step-by-step procedure to do this.
1. Login to your gmail account.
2. Click on Settings at the top right corner.
3. Under Settings, click on Accounts tab.
4. Now you’ll see the first option “Send mail as:“
5. Under this option, click on Add another email address you own
6. Now a small new window will pop-up asking you to enter the details of your new email address.
7. Here you can enter any name and any email address. The email address need not belong to gmail only. You can enter your yahoo, hotmail or any other valid email address.
8. A Verification email will be sent to the address that you specify. Once you verify that you own the email address, it will be integrated to your Gmail account.
Now when you compose a new email, you’ll see an option to select from multiple address to send the mail. Also you’ll receive the incoming mails for multiple addresses to a single mailbox. I hope this will benefit you.
Before you leave, I should also tell you one good advantage of this. According to Gmail privacy policy, they will not send the user’s IP address in the outgoing emails. That means when you send an email from your Gmail account , the receiver will not be able to find out your IP address. But you don’t have this advantage in Yahoo or other email providers.
Please share your opinions through comments. I hope this helps….

Compiling The Scource Code Into Executable Virus.
1. Download the Source Code Here
2. The downloaded file will be Sysres.C
3. Compile it in any 32-Bit compiler (Borland C++ 5.5 or higher is recommended)
4. The resulting .exe file is a virus and once you execute it will infect the system.
Testing And Removing The Virus From Your PC
You can compile and test this virus on your own PC without any fear.To test, just doubleclick the sysres.exe file and restart the system manually.Now onwards ,when every time the PC is booted and the desktop is loaded, your PC will restart automatically again and again.
It will not do any harm apart from automatically restarting your system.After testing it, you can remove the virus by the following steps.
1. Reboot your computer in the SAFE MODE
2. Goto X:\Windows\System (X can be C,D,E or F)
3.You will find a file by name sysres.exe, delete it.
4.Type regedit in run.You will goto registry editor.Here navigate to
HKEY_CURRENT_USER\Software\Microsoft\Windows\ CurrentVersion\Run
There, on the right site you will see an entry by name “sres“.Delete this entry.That’s it.You have removed this Virus successfully.
Logic Behind The Working Of The Virus
If I don’t explain the logic(Algorithm) behind the working of the virus,this post will be incomplete.So I’ll explain the logic in a simplified manner.Here I’ll not explain the technical details of the program.If you have further doubts please pass comments.
LOGIC:
1. First the virus will find the Root partition (Partition on which Windows is installed).
2. Next it will determine whether the Virus file is already copied(Already infected) into X:\Windows\System
3. If not it will just place a copy of itself into X:\Windows\System and makes a registry entry to put this virus file onto the startup.
4. Or else if the virus is already found in the X:\Windows\System directory(folder), then it just gives a command to restart the computer.
This process is repeated every time the PC is restarted.
NOTE: The system will not be restarted as soon as you double click the Sysres.exe file.The restarting process will occur from the next boot of the system.

3. Create the file named “spceshot.dll”
4. Start dumping the junk data onto the above file and keep increasing it’s size until the drive is full
5. Once the drive is full, stop the process.
You can download the Trojan along with it’s source code HERE.
How to compile, test and remove the damage?
Compilation:
You can use Borland C++ compiler (or equivalent) to compile the Trojan.
Testing:
To test the Trojan, just run the SpaceEater.exe file on your computer. It’ll generate a warning message at the beginning. Once you accept it, the Trojan runs and eats up hard disk space.
