How do I know if my computer has been hacked?

The most common thing in computer's hacking is, a computer to be hijacked first then hacked. Sometimes it can be difficult to detect a hacker on a computer. We have featured some of the most common things that change after a computer is hacked. Take a look:

Automatic installation of new programs:
In such critical situations, you will see some new programs or files in your computer system without manual installation. If you are the only user on the computer and new programs are installed, this could be an indication of a hacked computer. Following is the list of indications, take a look:

• program received updates that included new programs or files.
• Modifications in Registry settings.
• Error message or indication in Registry settings.
• Automatic executions of unnecessary programs.

Unsuccessful Admin Login:

If you are unable to log on to administrator account without playing with password, it may have been hacked. There is no reason why a password would change on its own. Log into an administrator account to change your accounts password. 

Computer doing things by itself:

When someone is remotely connected to a computer via network, they can remotely control any device. For example, a mouse cursor could be moved or something could be typed. It can be done via Trojan programs. If you see the computer doing something as if someone else was in control, this can be an indication of a hacked computer.
