INTRODUCTION
The Internet has become an important part of the daily life of many people. More and more people are making use of services that are present on the Internet. The Internet has evolved from a basic communication network to an interconnected set of information sources enabling, among other things, new forms of interactions and market places for the sale of services and products. Online banking or advertising are common examples of the commercial aspects of the Internet. Consider as in the physical world, there are people on the Internet with harmful intentions that struggle to enrich themselves by taking benefits of legal users whenever money is involved. Malware (i.e., malicious software) helps these people fulfilling their intents.

“Malware” is a term that can be used for any software that gets installed and activated on our device and performs unwanted actions and tasks. It often does so for the benefit of the third party. Malware programs can range from being simple annoying programs like adwares (pop up advertisements) to cause serious damage or invasion on one’s system[9]. The damage can be unmentionable as it can cause various threats like stealing passwords and data or infecting other machines that network with the infected device.
Majority of the malware programs are developed with an intention of data theft. They are designed to transmit information about the user for any third party interest. They generally keep a track of the user’s browsing habits for benefit of any third

Day to day the number of malwares are increasing and approximately every day thousands of new malwares are introduced to the internet via various resources. Thus it becomes a need for the sake of one’s safety that a system to detect and curd these malwares has to be developed.
MALWARE DETECTION TECHNIQUES
Techniques used for malware detection can be broadly classified into two categories: anomaly-based detection and signature-based detection. A special type of anomaly based detection is specification-based detection. Fig. 2. Types of Malware Detection Techniques
Signature Based Malware Detection Technique
Signature based detection uses the knowledge of what is considered as malicious to finds out the maliciousness of the program under inspection.[3] Commercial antivirus scanners look for signatures which are typically a sequence of bytes within the malware code to declare that the program scanned is malicious in nature. Basically there are three kinds of malwares: basic, polymorphic, metamorphic malwares. In basic malware the program entry point is changed such that the control is transferred to malicious payload. Detection is relatively if the signature can be found for the viral code.

Detection phase After obtaining the parameters, HsMM could be used to check whether the given observation sequences of SNMP-MIB variables correspond to normal profile or bot profile by calculating their average log likelihoods. The forward-backward algorithm is used to calculate a sequence’s likelihood against a given model. ALL values of training sequences for the normal and botnet systems are computed. If the observation sequence’s ALL value lies in a particular confidence interval, then it will be considered as normal profile. Similarly confidence interval for botnets is identified.
Also upon detecting a malware, Webroot is known to run the scan on the infected system repeatedly until the system is declared clean. Webroot is a very quick install on the system and has the silent install feature as well available in case the install has to be done without the system user’s interaction. Webroot is known to be the smallest and the lightest of all the anti-virus and anti-phishing software products which are available out there in the market currently. Webroot ranks higher than other AV solutions in certain marks like, a) providing endpoint security 150 times faster than Symantec, b) writes, opens and closes files 16 times faster than Microsoft, c) Uses almost 780 times less hard disk space to install and uses 1/3 less resources than Kaspersky, d)
The fundamental spread vector is bundling. The shady instrument hitches a ride with pirated applications, shareware & freeware which mediate the installation. The host is alluded to as a download customer. It offers the stealthy program as a bonus tool. You can have it installed or deselect it.
It offers a secure fitting together between internet browsers and websites, letting you to communicate secretive data online. Physical Layout • Topologies; topology can be measured as a computer-generated nature or construction of a system. This shape does not agree to the real physical plan of the policies on the computer network. • Ring; basically in a ring system each device (workplace, waiter, and copier) is related to two other devices, this systems a ring for the signs to travel around. Each packet of data on the network trips in one way and each device collects each box in turn until the journey 's end device receives it.
Always install the application from trusted source or device manufacturer 's store. Before downloading read app description carefully and at the time of installation deny all permissions those seems untrusted. Step 02: Delete all messages received from the unknown source that inquire for your information. Do not ever open any link in the messages, a hacker may still your information and install malware on the device. Step 03: Always keep updating your device firmware.
This can help delete all the malware or malicious content on the computer’s system. This can be the only way to save a computer at times, for example if the memory storage has been filled up with worms that keep copying themselves until the system stops responding. If this is the case then deleting everything can be the easiest way to stop. Other times, the malware is not visible to the user allowing it to travel through the system’s hard drive and damage the files. It can also be disguised as useful files.
They hold information about the addresses of computers attached to the network and can forward data efficiently to the correct location via an appropriate route. They are generally used as gateways where a local area network is connected to a larger network such as the internet. Web browsers are software programs that allow a person to explore the Internet in an easy to use way. Navigating the Internet through a series of hyperlinks you can browse the Internet. Examples of popular browsers are Chrome, Internet Explorer, Firefox, Safari, and Opera.
The capsid carries DNA or RNA1 which give the virus its unique features. In this state the virus is metabolically inert, or it doesn’t use any of its resources to make energy. 1 - Ribonucleic acid: it performs as a messenger for the DNA cells; it manufactures the proteins for living cells using the DNA’s genetic information. When were viruses discovered and who discovered them?
The Trojans attacks the network by modifying blocking and even delete data. The last attack that I will describing is Worms, worms and viruses are similar in the way how fast they spread through the network, worms also fill up the storage space with junk the result of this slows down the
To identify if the disease is a virus, there must be evidence shown that the cells do not undergo binary fission; they create new particles like an assembly line. Another trait of a virus is they have a one, single nucleic acid, whether that be DNA or
It allows the user to interact with the computer in a sophisticated way such as managing files.
Being able to identify unknown microbes from systematic testing is what makes the field of microbiology so important, especially in infectious disease control. Using the testing procedure laid out by the microbiology field we are able to identify unknown bacteria present in our everyday lives, and along the way learn a lot about their characteristics that separate them from other types of bacteria. Being able to do this is vital in order for us to understand why microbes are present in certain places, how they are able to grow and what restricts their growth, that way they can be combatted if necessary. These techniques for determining unknowns are also important for isolating and testing infectious disease microbes in order to prevent spreading. Another important aspect of being able to identify unknown microbes is the
Certain applications here at First World Bank Savings and Loan are mission-critical for our organization, we will want to monitor appropriate security lists maintained by their sponsoring groups. Linux has antivirus and anti-malware systems. Some of these systems are designed to minimize the risk of Linux as a malware carrier between Microsoft systems. But such systems also address malware written for Linux, such as rootkits, Trojan horses, worms, and more.
Others ways to protect a computer from virus are: if you don’t know the sender of a message with an attachment, don’t open it; back up your files often to keep your data safe from virus; use routers and firewalls to monitor your computer activity and block unauthorized entries; disable macro security settings in working with Word or Excel to prevent running without permission.
Causes According to Amin & Noor (2013), the E-consumers generally refer to the purchaser of goods and services over electronic systems such as Internet and other computer networks. This new group of consumers is increasing in number over the years as on-line shopping become a trend and manifestation of modern life style. Based from the Paynter & Lim (2001), E-commerce would provide consumers with benefits such as interactive communications, fast delivery, and more customization that would only be available for consumers through online shopping. Product information in the Internet is more compact and it ranges from various sites.
