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.

 Integrity, which means guarding against improper information modification or destruction, and includes ensuring information nonrepudiation, accuracy, and authenticity;

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.

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.
