Nowadays, there’s absolute confidence that the Internet has become an important a part of every organization, home, and even for everybody. extra than millions and millions of customers around the world use the Internet on each day basis. Recently, the Internet has become used in advertising and has enormous financial power in marketing and technology over the Internet. The primary goal of the ad is to target the advert to intentional or unintentional users. Consequently, users are vulnerable to malicious software which known as “Malware”. Malware is a software which brings threat to a computer system. Malware is classified into several forms worms, viruses, trojan horses, hijacking, logic bombs, spyware and adware and so on. Which steal protected data, delete documents or add software not approved by a user. This research will discuss two types of malware: spyware and adware.
Before talks about spyware and adware, we need to know that threats vary by forms, sources, and degree of severity. Also, it is classified into three levels of information protection from attacks. First, is the easy level that depends on the consequences that could result from system intrusion and access to protected data, for example, access to student flags by an unauthorized party. Second is the medium level which depending on the consequences as well, but here the consequences are higher than the previous level when unauthorized access to this data can affect the lives of some people and cause them harm. For instance, access to data can cause limited financial losses to unauthorized persons. Finally, is the complicated level. The consequences are at such a high level that such leaks sometimes kill people and therefore need high protection against unauthorized access. For example, access to patient data in the hospital, and deliberately change the type of disease, which entails that the doctor to treat the patient because the name of the disease is suffered by the patient and therefore may cause the wrong treatment of the patient’s death! ranging from easy, medium to complicated threats. These attacks target several fundamental aims which should be characterized by any safe system. Scientists named three important part of information security that called CIA triad.
Figure 1. CIA triad.
Integrity, which means guarding against improper information modification or destruction, and includes ensuring information nonrepudiation, accuracy, and authenticity;
Confidentiality, which means preserving authorized restrictions on access and disclosure, including a means for protecting personal privacy and proprietary information; and
Availability, which means ensuring prompt and reliable access to, and use of, information.
In recent years, there are certain types of malware, known as spyware and adware there are most widespread threats on the Internet, secretly infecting user computer without permission to start a variety of illegal activities. These programs are created by manufacturers with professional developers instead of amateur virus writers. Spyware gets on a user’s computer while browses the Internet or by recording keystrokes. Which leads to slow down the Internet and create some of the sudden changes in the system due to many pop-up ads and their background behavior. At worst, this can lead to the need to reload the system software. If the computer affected by spyware or adware all the user’s credit card, bank account and other personal data which are registered can be stolen. So, we should know what are spyware and adware? how to get them, how to prevent them and get rid of them.
4.History of spyware:
“Public references to the term “spyware” date back to late 1996, when it appeared in an industry article. By 1999, it was used in an industry press release, described as we define it today. The term was an instant hit in the mass media and among its audiences. Soon after, in June 2000, the first anti-spyware application was released. In October 2004, America Online and the National Cyber-Security Alliance performed a survey. The result was startling. About 80% of all Internet users have their system affected by spyware, about 93% of spyware components are present in each of the computers, and 89% of the computer users were unaware of their existence. Out of the affected parties, almost all, about 95%, confessed that they never granted permission to install them. ”
Table 1. Which Phrase Best Describes What “Spyware” Could Be?
Conversely, for the respondents that had heard of Spyware, Table 1 shows the survey data details. As such the user groups who understood what Spyware is unsurprisingly the Advanced Users and IT Professionals; however, there does seem to be some misunderstanding of what Spyware is. From the data, 18% (35 respondents out of the 196 respondents that know what Spyware is) misidentified Spyware as either a ‘Virus’ – 9 respondents, or ‘Adware’ – 7 respondents, or finally a ‘PopUp’ – 19 respondents. Survey respondents, in general, do seem to know from this survey what Spyware is, as can be seen in Table 1, where 79% or 161 respondents out of the total of 205 respondents correctly knew what Spyware is.
5.The Concept of Spyware:
Spyware is any software that covertly gathers user information through the user’s Internet connection without user knowledge. Spyware applications are typically bundled as a hidden part of freeware or shareware programs that can be downloaded from the Internet advertisement. After installed, the spyware detects user activity on the Internet and transmits that information in the background to someone else.
M. Jaeger and N.L. Clarke, Network Research Group, University of Plymouth, Plymouth, UK, The Awareness and Perception of Spyware amongst Home PC Computer Users.
There was a survey published through email and completed by 250 users. The purpose of that to figure that if consumer knowing or understand spyware.
The following table shows that.
Table 2: Home PC Users Opinion of Website Categories That Have Spywar.
Example of spyware:
Figure 2. Source: Wikipedia Bonzi Buddy.
Users are invited to install Bonzi Buddy on their computer. Then, Bonzi will explore the Internet with a user as a friend for the user and sidekick! Bonzi can talk, walk joke, browse, search, e-mail, and download. A best friend! Also, he could compare prices on the products which the user like and help to save money! In addition, it is free; So, most of the people would think this is a great add-in to download and unfortunately, children are the target.

For this reason, they are usually referred to as annoying ads. Adware is hard to remove once installed on a computer, it may be in the user interface of the program. Additionally, it will be presented to people on the screen during program installation.

13.How Do Spyware and Adware Work?
Adware: Adware for the most part enters a client’s PC amid routine Web surfing. Developers make programming that runs like an infection or Trojan steed through download a distributed document sharing customer that has shrouded adware. At that point, the promotions start to appear after the program documents are stacked onto the framework. From that point onward, the program may plant following treats, keyloggers or perform meddling hard drive checks. Along these lines, vindictive adware program may send Visa numbers, passwords, pictures and other touchy data to untrusted part who may exploit this data to take from the client.

Then, will report back to web sites the user has visited to build a marketing profile about him to use to sell targeted advertisements which user interesting on. In addition, Spyware will download software and other components that affect system performance which leads to affect computer performance.
14.Methods Used for Installation Adware and Spyware:
Note: Spyware will infect the computer just when it has an adware in the system.
There are many ways for downloading them here are the most commons ways:
Drive-by-downloading: Drive by downloaded is the act of provoking an individual to install software when the user browses the website without the individual, in fact, wishing setup different software at the beginning.
