How to remove an hacker from a computer When a computer has been broken into, the hackers leave behind software called a rootkit. A rootkit is used by hackers to gain administrative privileges on the computer as well as put in additional security holes to regain access if the rootkit has been discovered. Rootkits are also designed to hide themselves from the real administrators of the computer, as well as disable any anti-virus programs that might discover them. As soon as hackers gain administrative access, it is almost impossible to remove all traces of the intrusion since they may have added many extra security holes on top of what's included in the rootkit. Turn off the computer suspected of having hackers. This step will prevent the hackers from breaking into other computers on the local network. Power up the computer. Follow the on-screen instructions during the boot up to enter BIOS setup and configure boot-up order to boot up from the CD-...

Acting in a timely manner is essential when dealing with the consequences of a hacked computer. As soon as you suspect that your computer's security has been compromised, you should assess the damage caused by the computer virus or the hacker and, based on that assessment, either wipe your computer clean or attempt to remove the malicious application using a reputable antivirus program. Assessing and Addressing the Damage Before even attempting to fix your computer, your first goal should be to assess the situation and take measures to safeguard your data. Consider the following questions: Are you certain that your computer has been hacked? An application that recently started crashing, a slow computer or an unresponsive operating system, for example, may not always be caused by malicious software or a hacker.
