A rootkit is malicious malware designed to remotely access or control a computer without being detected by users or security software programs. Using rootkits, cybercriminals can execute files,steal information, modify configurations, alter software, or even install more malware. Rootkits can be included in software applications and can enter a computer through phishing attacks or through a security vulnerability. A rootkit is very difficult to remove, so prevention is key.

Trojans behave like a Trojan horse in Greek mythology. The soldiers hid inside of the horse to penetrate the city wall of Troy and waited until nightfall to attack. A Trojan works in a similar way.

Ransomware locks your files and demands you pay a ransom to unlock and access them again. This type of malware is rapidly becoming more advanced. It can immediately start deleting files as soon as you are infected, pressuring you to pay up. One of the most common ways that ransomware can access your computer is through phishing. Phishing uses email as a weapon, disguising itself as a legitimate email and tricking the user into opening the email or attachment.
