When it comes to personal protection on our personal devices, there are many preventive measure that need to be followed. A firewall must be turned on to help protect computers from hackers that might try to gain access. Installation and update of antivirus software and antispyware technology, will prevent malicious programs from embedding on the computer, most types of antivirus are set up to update automatically. Just as a company, the operating system needs to be up to date to fix security holes, this will make a computer to have the latest protection. Finally, as an individual being careful with what is downloaded in the computer is a major protection, carelessly downloading e-mail attachments can circumvent even the most vigilant anti-virus software
Or we can say that trust relationship is broken. Violates certain laws emphasised by TCP (transmission control protocol), IP (internet protocol). Creates a platform for one’s personal computer for various parasitic or very suspicious activities by targeting some other person’s computer. Parasitic computing exploits protocols in order to do computations within the communication infrastructure between server and
Introduction At present day, computers are exposed to a lot of damage due to malicious viruses circulating in the world of technology. Due to this, antivirus software was created. So, an anti-virus is a program that protects computers from malicious programs or any unknown issues. In this essay, I will cover the history of Norton antivirus, the mechanisms of it, features, disadvantages and advantages of such. History of Norton Antivirus Before Internet access was widespread, viruses were usually transmitted by infected floppy disks.
On the other hand, this does not mean they are fully protected because anyone may obtain a user’s information. In other words, the most common Internet crimes are frauds. Today, not only humans getting viruses, but computers are also. Computers are mainly getting these viruses from the Internet, yet viruses may also be transferred through floppy disks. However, people should mainly be concerned about receiving viruses from the Internet.

Moreover, Firewalls do a very good job of filtering incoming traffic from the Internet; however, there are ways to circumvent the firewall. For example, external users can connect to the Intranet by dialing in through a modem installed in the private network of the organization. This kind of access would not be seen by the
First, users create their passwords by themselves. For easy memorization, users tend to choose relatively weak passwords for all websites . This behavior causes a risk of a domino effect due to password reuse To steal sensitive information on websites for a specific victim (user), an adversary can extract her password
