An attacker can intentionally install malicious software on your computer.
Computer users can be tricked into installing malicious software themselves, believing they are installing some piece of “necessary” software. Computers can be infected with malware that actually installs other forms of malware.
If a computer’s security software is out of date, it could be exploited either by visiting a malicious website or by being attacked by a malicious or infected computer.
Take security steps to prevent an attacker can intentionally install malicious software on your computer.
Always keep your antivirus software and Web browser versions up to date and use a firewall. Antivirus software stops threats by scanning your computer for suspicious files. A firewall makes your computer invisible to attackers. It also makes it harder for criminals to get data into and out of your machine.
