Discuss different types of threats and malicious program (malware) that can damage a computer, mobile device or disrupt any system. Search for information on current known malware program. Based on the information that you have found, create a table to list different types of malware, what it does, and how it can be repaired or removed. These information is useful for you to prevent any malware from damage your computer system

Types	What it does	How to repair
viruses	Viruses infect files which are used by others on a network, through removable storage devices, or via email attachments.	Install anti-viruses
worms	Worms penetrate remote machines and launch infected copies using email, instant messages, file sharing (P2P), IRC channels, and network transfer on LANs and WANs. They can be carried in email attachments and can attack insecure network access points or attack vectors – vulnerable entry points in applications or the operating system. Some worms are known as "fileless" or packet worms. These spread on a network and directly target and penetrate the computer RAM.	Use a firewall. Either make sure your Windows Firewall is turned on (run a search for Windows Security Center on your computer to configure) or install a trustworthy firewall program to help block unwanted internet traffic. Note that you should not run two firewalls at the same time, as this will cause errors and can actually make your computer more vulnerable
trojan	Trojan horse appear benign until they are downloaded and become resident on your computer system. Trojans are a serious threat to security. Once resident on the system they can open a "backdoor" to the computer (for example, port 21). By doing so they gain remote access and other security breaches can be performed. Trojans are one of the most common tools of the malware trade and are used in conjunction with other malicious software. As a result, there are numerous activities that these items can perform including collecting sensitive data such as banking information and using the host machine as a proxy so that other remote attacks can be performed such as a Denial of Service (DoS) attack.	Install anti-virus software.
hoax	Designed to trick an intended audience into believing a falsehood; it falsely warns the user about a virus and encourages the message to be forwarded.	Install a security program. Boot your system in safe mode. Run the security program to eradicate the hoax from your computer
Denial of Service (DoS) / Flooder	sending massive quantities of data to an Internet connection such as a server or a network so as to disrupt or flood the service	Activate firewalls.
Bot	Gather information (such as web crawlers), or interact automatically with instant messaging(IM), Instant Relay Chat (IRC), or other web interfaces. They may also be used to interact dynamically with websites.	Install a bot remover program.
Spy-ware	Spyware attach themselves to your operating system in nefarious ways. They can suck the life out of your computer's processing power. They're designed to track your Internet habits, nag you with unwanted sales offers or generate traffic for their host Web site.	Installing anti-virus or anti-spyware
Exploit	An exploit is a piece of software, a command, or a methodology that attacks a particular security vulnerability. Exploits are not always malicious in intent—they are sometimes used only as a way of demonstrating that a vulnerability exists. However, they are a common component of malware.
