But most of them use same basic detecting methods such as real-time protection, signature-based on detection, heuristics detection and rootkit detection. In antivirus industries, the most significant job is to classify the known viruses based on their activities, even one single malicious programs have several malicious activities and propagation routine.

Week 3 Submitted by: Sandeep Kaur (100574107) QUESTION 2: What are the security services of windows network security? ANSWER: The services which are working together to maintain Window network security are: • Active Directory: These directory is a container of information about objects, people, places, and things. A directory gives users a logical view of these objects, but in a form that makes the information searchable, useful and reusable. • Kerberos: The Kerberos is a protocol which defines how
Anti-Malware Free have some security features such as Anti- Malware/Anti-Spyware, Malwarebytes Anti-Rootkit and Advanced Malware Removal. [9] Anti-Malware/Anti-spyware feature as usual, this is for detects and delete malware such as, viruses, Trojans, worms, rootkits, adware, and spyware in computer system to make sure information security integrity. Malwarebytes Anti-Rootkit is for removes rootkits and repairs the files they damage. This feature is useful for the computer system which is after infected
need of the company structure. Antivirus software is computer software used to prevent, detect and remove malicious computer viruses. Most Antivirus software also works against other types of malware, such browser hijackers, keyloggers, backdoors, rootkits, trojan horses, worms, malicious adware and spyware. There are numerous types of Antivirus protection software to choose from. Signature-based detection: relies upon signatures to identify malware. This can be very effective, but cannot defend against
Malicious software, or simply malware, can be described as software that a computer user never authorized to be loaded. This means that the software can be found on user’s computer without his or her knowledge. Furthermore, a malware can be described as software that collects private information from any computer without user’s knowledge and authorization. As the name suggests, this software is malicious and can do great damage to a computer, mobile device, or other related devices. This damage can
Hacker subculture[1] is heavily dependent on technology. It has produced its own slang and various forms of unusual alphabet use, for example l33tspeak. Such things are usually seen as an especially silly aspect by the academic hacker subculture.[citation needed] In part due to this, the slangs of the two subcultures differ substantially.[citation needed] Political attitude usually includes views for freedom of information, freedom of speech, a right for anonymity and most have a strong opposition
for software that may harm your computer. People often use malware and viruses interchangeably, but they are not the same thing. Viruses are a form of malware. There are many forms of malware, but the most common types are viruses, worms, spyware, rootkits, and trojans. A virus is a piece of code that spreads through some user interaction(going to a shady website or downloading a file), usually written with evil intentions. A virus infects files that already exist on systems. They are not their standalone

1.0 Introduction In our modern society where technology is evolving, the people who are exposed to computers each day are also increasing. Using computers have become part of our daily lives to the extent that the world would not function as it would now without the use of computers. With that, criminals are moving on to using computers for their criminal activities and thus computer crimes are born. Every now and then we will hear news of companies getting hacked, government websites being defaced
The history of cybercrime goes back to 1971 and the first computer virus called the Creeper which was created by Bob H. Thomas, who was a BBN engineer (Dalakov, Meltzer, and Phillips). BBN which stands for Bolt, Beranek and Newman, is now Raytheon BBN Technologies (“About”, Dalakov). A computer virus is a program that is created to cause damage to a computer or perform other malicious acts (204). The Creeper virus was designed to infect the ARPANET network. The ARPANET, which stands for Advance
• A computer virus is a program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes. They have the ability to replicate themselves to the point of using all the available memory, slowing the machine or bringing down the system. All computer viruses are man-made. An even more dangerous type of virus is one capable of transmitting itself across networks and bypassing security systems. Type of Virus • File infecting virus This type of computer virus
program, which has the capability of exploiting other software programs in order to piggyback[1]. The terms viruses and malwares are used interchangeably, however, in technical terms, the viruses are a subset of malware and so are trojans, worms and rootkits. The name for the “Computer Virus” has actually derived from its biological counterpart because of their proximity in properties. Similar to the functioning of biological viruses, a computer virus must use another program to exploit some other program
Antivirus programs can have many differences between applications or they can be very similar. There are programs that can be paid for or programs that can be acquired for free. Because having an antivirus program installed to protect the computer and its user is essential for optimal performance and online safety, a program must be evaluated to make sure it fits the requirements for each user’s need and that the computer meets the software’s requirements for installation. One such antivirus program
encryptions which sometimes cause problems for the honest user who actually purchased the software. They sometimes go as far as to invade your own privacy by installing surveillance software without you knowing about it. This software is called a rootkit and any common anti-virus program would detect it. It is a program which can prevent you from removing it and can perform various functions, such as preventing you from installing certain software. It is a total invasion of privacy and the companies
A firewall is a hardware or software device, or sometimes a combination of the two, that monitor, record, and filter all data that is coming into or out of the network they are connected on based on a set of rules implemented on the device or software program. A hardware firewall is used most often when multiple devices on a network need to be protected by a firewall. Hardware firewalls are a necessity if you need to have a centralized point for protection and easy management of the firewall. You
