Packet Filters and Firewalls
From the December 1990s up until around January 2012, it was very similar to see a new type of malware, called worms, that harmed one or more remote vulnerabilities in some beleaguered software products. Sometimes these worms simply used default username-and-password combinations to infect network environment.
Famous Virus Catchy Names
In Windows CIFS networks by copying themselves with catchy names. Famous examples are “I love you,” Conficker, Melissa, Nimda, Slammer, and Code Red.
Computer and cyber network resources
Because many worms used the computer and cyber network resources to infect computers and other associated devices, then Antivirus Industry decided to examine networks for incoming and outgoing traffic. To do so, Antivirus software installed drivers for network traffic analysis so they can antivirus a check on the worm which was used to infect network along with cyber-security threats, and firewalls being used to block and detect the most common known attacks on computer systems. As with the previously mentioned features, this is a good source of bugs, and today worms are almost gone and new threats keep on appearing. This is a feature in Antivirus products that antivirus not been updated in years; as a result, it is likely suffering from a number of weakness because it has been practically abandoned. This is one of the remotely exposed attack surfaces that are analyzed in the coming articles.

As Antivirus software tries to protect the computer and network users from malware, the malware also tries to protect itself from the updating of the Antivirus software. In many cases, the malware will try to kill the processes running in the computer systems of the installed Antivirus product in order to disable it and to stop running inside the computer system. Many Antivirus software and products implement self-protection techniques in kernel drivers to prevent the most common killing operations which are running inside the computer, such as issuing a call to ZZTerminateProcess. Self-protection schemes used by Antivirus applications, products and software can be based on stopping and denying calls to running processes with firm parameters and attributes for their Antivirus processes or preventing WriteProcessMemory calls to stop injecting into another process.
These techniques are usually suitable for kernel drivers; the protection can also be implemented and stored in user-land. However, relying on code running in user-land computer system is a failing protection model that is known not to Antivirus updated since 2000. In any case, many Antivirus products still make this mistake and which allow the malware to hide with the kernel files. Various Antivirus application and products that experience this problem will be discussed in the next article.
Working frameworks, including Windows, Mac OS X, and Linux, now offer against abusing highlights, likewise alluded to as security alleviations, similar to Address Space Layout Randomization (ASLR) and Data Execution Prevention (DEP), however, this is an ongoing advancement. This is the reason some Antivirus suites offer (or used to offer) against abusing arrangements. Some against abusing systems can be as straightforward as upholding ASLR and DEP for each and every program and library connected to the executable, while different methods are more perplexing, similar to client or bit arrive snares to decide whether some activity is taken into consideration some particular procedure. Shockingly, as is normal with ANTIVIRUS programming, most against misusing toolbox offered by the ANTIVIRUS business is actualised in user-land through capacity snaring; the Malware-bytes hostile to abusing tool stash is one illustration. With the appearance of the Microsoft Enhanced Mitigation Experience Toolkit (EMET), most hostile to misusing toolbox actualised by the ANTIVIRUS business either are inadequate contrasted with it or are just not up and coming, making them simple to sidestep.
Now and again, utilising against misusing toolbox executed by some ANTIVIRUS organisations is much more terrible than not utilising any hostile to abusing tool stash whatsoever. One illustration is the Sophos Buffer Overflow Protection System (BOPS), an ASLR usage.
