In line with technological and information advances, the more complex
types of attacks that occur in cyberspace. Apart from the various types of attacks

and AdBlock applications. Based on the results of trials and comparisons,
applications that have been made are able to detect 6 or 60% of the 10 URLs.
Kaspersky and McAfee applications can detect 70%, while AdBlock only detects 3
or 30% of 10 URLs that contain phishing
