Abstract—I was intrigued by the Antivirus term, how it works,, whether its designers understand the operating system more than the operating system vendors or not as well as the big question of how safe we are in practice because we are really rely on this term to protect all sort of businesses including web servers in which the eGovernment website is hosted, and many more questions I asked at the time. Also, Tanebaum in 2009 describes the contemporary operating systems as massive, inflexible, unreliable, unsecured and loaded with bugs, and that has been happening with the very presence of antivirus and their vendors who claim 100% protection against the variously clever malware. [4]

All of that was the real motive behind conducting this paper to evaluate the practical level of protection that the commercial antivirus provides by designing an empirical test. Not only testing them generally, but also, making a design-based comparison between them, but calling it antivirus should have been changed for a while because it does not quite cover the contemporary malicious software, which includes more than just viruses. On account of this, this project will call it on a malware scanner as many professionals do so.

To conclude, it was found that there is remarkable disparity between the malware scanners’ capabilities and the advertised ones. Also, the conventional design of the malware scanner was proved to be ahead of the combination technique that many security vendors have been using to design their own scanners. The other interesting fact according to today experts is that even security vendors are selling pitches because it is mere business, so they cannot be trusted blindly.
