Computer Tricks

If you don’t have a copy of the Ubuntu 9.10 CD downloaded, then click on the checkbox to Download the ISO. You’ll be prompted to launch a web browser; click Yes.

Select the drive letter that corresponds to the flash drive that you would like to use from the dropdown box. If you’ve backed up the files on this drive, we recommend checking the box to format the drive.

Finally, you have to choose how much space you would like to set aside for the settings and programs that will be stored on the flash drive. Considering that Ubuntu itself only takes up around 700 MB, 1 GB should be plenty, but we’re choosing 2 GB in this example because we have lots of space on this USB drive.

Click on the Create button. It will take some time to install even on super fast PC.

Eventually it will finish. Click Close.

Thats it Now you have made bootable ubuntu.

Now you have a flash drive that will boot into a fully capable Ubuntu installation, and any changes you make will persist the next time you boot it up!

Pls do comment for anyqueries..

This is a simple virus written in C. It will block websites on victim's computer system. This C code is only the implementation of my previous post How to block a website without any software
I am implementing that process by a C program to create it as a virus. Once the virus is clicked, it will block the some specific websites on victim's computer. The website which you want to block is mentioned in the source code of the program. Change the list according to your choice.


Download source code of  C program (virus)  :Download here


How to use:

You need to have a C compiler for that.

• Compile and build the C program and generate the EXE file.
• Run the EXE on your computer to check it's working.
• Go to the browser and try to open google or facebook. ;)
• to unblock those websites. try the procedure given in my older post How to block a website without any software and delete the new entries in the file hosts created by this virus.
• Now send this EXE to the victim as a game or any other software.
