In most cases computer problems do not happen due to computer hacking. Firstly it has to be a virus that gets into your computer and only then it can be hacked. Though it is tough to reach out to the hackers, but whether your computer is been hacked or not can be detected through the most common signs that can be noticed if it has been hacked. These are:

1.New programs get automatically installed

Suddenly you might find new files or programs are appearing in the computer. Though there may be other reasons for new programs to get installed, like, if there are other users, if you have installed a program allowing other peripheral programs to be installed, and if a virus is there in your computer. But programs like trojans and Backdoors are the most common programs which get installed on a computer in most cases if it has been hacked. These programs allow the hackers to get access to the important information that are stored on your computer.

2.Computer passwords get changed

In most of the times, if your computer is hacked, one or more of your online accounts will show that the password you are providing is either not matching or that it has been changed. If you try to go for "forget password" assistance, and it doesn't work, then it is most probably a sign that your computer has been hacked. The chances get more closer, if the same thing happens to your offline passwords, like windows password, your computer login password etc.

3. Spam E-mail
Other than getting access to your bank accounts, the hackers also make use of your email accounts to spread spam mails and shifting the blame on you. So if your accounts show that spam emails are been sent form your email addresses, it is another sign of you being trapped by a hacker. You might also end up receiving bounce back e-mails from unknown email addresses.

4. Increased network usage

The hackers need to remotely connect to your internet network. In that case if you have a bandwidth monitor program installed on the computer, it can help help you know which programs are being using the bandwidth you are subscribed to.

5. Modem users
If you find your computer dialing the Internet on its own, it might be an indication that a program is trying to connect to the Internet without your knowledge. And in that case it can be directly indicative of a hacker trying to do so.

Apart from these there can be even some more signs that is indicative of your computer being hacked.

6) Unknown programs prompting for access
7) Security programs getting uninstalled automatically
8) Computer operating of its own.

So if you find one or more of these things happening, then it is time for you to be concerned and take the necessary precautionary steps.
