Computer use is becoming part of our lives every other day however there have been considerable threats of computer viruses in the recent past. Viruses have had adverse effects on data and programs ranging from formatting hard disks, damaging information infrastructure, suddenly restarting machines, deleting or modifying data and in some cases mild effects such as slowing down machines or producing irritating sounds. Viruses have been a major cause for worry especially with the advances in data processing, storage and movement of information technologically. Many computer users and organizations especially the computer intensive organizations have had to invest heavily in dealing with viruses particularly those organizations running the windows platform. These computer viruses have been defined by their characteristics of entry and multiplication without the user’s notice as well as diverting the normal functioning of the computer. This paper seeks to define a virus and explain its related terms such as malicious software, worms, and Trojan horses. It explains vulnerabilities of operating systems in relation to viruses, it makes an observation on strengths of Linux versus Windows, outline the present state of affairs, apart from using anti-virus software, there are other procedures which can help protect against viruses which are also mentioned, the future of computer viruses and the conclusion that the Internet is serving its purpose of interconnecting computer and hence promoting distribution of viruses then makes some recommendations on viruses.

User Awareness

Despite the recent increased attention afforded malware by the popular press, there appears to be a dearth in user awareness and understanding of certain aspects of the security paradigm. This chapter presents a comparison of user awareness levels of rootkits, spyware, and viruses between U.S. and Chinese users. The results of a survey of 210 U.S. respondents and 278 Chinese respondents indicate that respondents’ awareness and knowledge of rootkits is well below that of spyware and viruses. Data analysis further reveals that there are significant differences in Chinese and U.S. user perceptions with regard to spyware and computer viruses. However, there is no difference in cross-cultural awareness with regard to rootkits. Due to the ubiquitous nature of the Internet, rootkits and other malware do not yield at transnational borders. An important step to mitigate the threats posed by malware such as rootkits is to raise awareness levels of users worldwide.

Some words about attitudes to technology: many people are afraid of new technology and, with the increasing presence of the Internet and computers, the term technophobe has appeared to refer to those of us who might be wary of these new developments. More recently, the term digital native has been coined to refer to someone who grows up using technology, and who thus feels comfortable and confident with it there is a tendency to call computer users either technophobes or technogeeks ( a term for a technology enthusiast) the truth is that most of us probably fall somewhere between the two extremes. A large part of the negative attitudes teachers have towards technology is usually the result of a lack of confidence, a lack of facilities or a lack of training, resulting in an inability to see the benefit of using technologies in the classroom. It is also often the case that teachers may not be fully in control of their work situations. A teacher may want to use more technology in their teaching, but the school may not have the facilities, or, on the other hand, a teacher may be instructed to start using technology for which they feel unprepared or untrained.

Share Information

People have always shared information through chains and networks of testimony. It is arguably part of what makes us human and enables us to live in cooperative communities with populations greater than 150 or so. The invention of the internet and the rise of social media have turbocharged our ability to share information. This chapter develops a normative epistemic framework for sharing information online. This framework takes into account both ethical and epistemic considerations that are intertwined in typical cases of online testimony. The authors argue that, while the current state of affairs is not entirely novel, recent technological developments call for a rethinking of the norms of testimony, as well as the articulation of a set of virtuous dispositions that people would do well to cultivate in their capacity as conduits (not just sources or receivers) of information.

Analyze Data

With the ubiquity of web tracking, information on how people navigate the internet is abundantly collected yet, due to its proprietary nature, rarely distributed. As a result, our understanding of user browsing primarily derives from small-scale studies conducted more than a decade ago. To provide an broader updated perspective, we analyze data from 257 participants who consented to have their home computer and browsing behavior monitored through the Security Behavior Observatory. Compared to previous work, we find a substantial increase in tabbed browsing and demonstrate the need to include tab information for accurate web measurements. Our results confirm that user browsing is highly centralized, with 50% of internet use spent on 1% of visited websites. However, we also find that users spend a disproportionate amount of time on low-visited websites, areas with a greater likelihood of containing risky content. We then identify the primary gateways to these sites and discuss implications for future research.

Heuristic Analysis

Backdoor or commonly also known as web shell is one of the malicious software that hackers use to maintain access systems that they have entered. Relatively few programs like Anti Web-Shell, PHP Backdoor Scanner circulating on the Internet, and can be obtained free of charge to deal with the issues above. But most of these programs have no actual database of signature behavior to deal with PHP backdoor / Shell nowadays. Then comes the contemporary Anti Web-Shell program that can deal with today's backdoor shell. This study uses an experimental method concerning previous similar studies and is implemented directly into the world of cyber security professional industries. By enriching the Regex dictionary signature and String Array Matching the actualized Anti Web-Shell program can detect more backdoor than similar programs that have existed in the past. The results of this study are in the form of a web application software in PHP extension. The application can minimize 100% of false positives and is twice as fast in scanning files because it is more specific in heuristic analysis scan.

The Impact

The internet is a basic source of information for many specialities and uses. Such information includes sensitive data whose retrieval has been one of the basic functions of the internet. In order to protect the information from falling into the hands of an intruder, a VPN has been established. Through VPN, data privacy and security can be provided. Two main technologies of VPN are to be discussed; IPSec and Open VPN. The complexity of IPSec makes the OpenVPN the best due to the latter’s portability and flexibility to use in many operating systems. In the LAN, VPN can be implemented through Open VPN to establish a double privacy layer(privacy inside privacy). The specific subnet will be used in this paper. The key and certificate will be generated by the server. An authentication and key exchange will be based on standard protocol SSL/TLS. Various operating systems from open source and windows will be used. Each operating system uses a different hardware specification. Tools such as tcpdump and jperf will be used to verify and measure the connectivity and performance. OpenVPN in the LAN is based on the type of operating system, portability and straightforward implementation. The bandwidth which is captured in this experiment is influenced by the operating system rather than the memory and capacity of the hard disk. Relationship and interoperability between each peer and server will be discussed. At the same time privacy for the user in the LAN can be introduced with a minimum specification.

Long Time

Computer viruses have been studied for a long time both by the research and by the application communities. As computer networks and the Internet became more popular from the late 1980s on, viruses quickly evolved to be able to spread through the Internet by various means such as file downloading, email, exploiting security holes in software, etc. Epidemiological models have traditionally been used to understand and predict the outcome of virus outbreaks in human or animal populations. However, the same models were recently applied to the analysis of computer virus epidemics. In this work we present various computer virus spread models combined with applications to e-health systems.

One of the significant advances in software design afforded by the internet has been the open source movement, an effort to collaboratively create software and make it widely and freely available to the online community. Although the open source movement started with Unix-like computer operating systems, it has expanded to include a wide variety of software programs, including tools to publish and analyze online surveys. This article introduces the open source movement and then profiles three leading open source survey programs: php Easy Survey Package (phpESP), PHP Surveyor, and the Moodle course management system.
