Designers should install software into the kernel because it is the basic operational unit of a computer and operating system as a whole. On top of that, the kernel has full access to computer re- sources, and this provides developers with unrestricted access to all resources hence installing software into the kernel enhances flexibility (Perla & Oldani, 2017). The kernel keeps track of the

various pieces of software running, it is in charge of keeping track of what memory is available and handing off bits of free memory to programs when they ask for it. The kernel manages all of the hardware devices and brokers interaction between the hardware devices and programs that are running. The kernel can look at the raw data on a disk and determine how it is laid out as files and present those files and the disks as places where programs can read and write data. The kernel also handles the flow of data through networks and between programs, managing connections, sending data where it is supposed to go, notifying the programs that data is available or that it's waiting. As with any computer op- erating system, it provides support for all the other software you run on your computer by providing hardware drivers and various system services like memory management, process management, and more. Viruses don’t invade programs. They invade a computer by becoming executable within the operating system. One route is by fooling people into installing them. You can’t fix stupid. Some viruses indeed get a foothold by exploiting a bug in some program. Sadly, we have never succeeded in eliminating all possibilities of

bugs. Some modern programming languages make it more diffi- cult to write programs with bugs, but it may still be possible, and we cannot always use those more robust languages. Developers should make it next to impossible for users to install programs by restricting their antivirus to only accept some applications. The only way one can get a program to run on a Juniper router, for in- stance, is for it to be digitally signed by Juniper. Even if you have administrative and physical access. Most people are not prepared to live with that level of security. They want to install third-party software, for instance, and not be limited to only authorized ven- dors. Most viruses now are installed and run deliberately, by users. Not because they want to but because they were tricked by social engineering in an email or on web pages. One of the challenges antivirus developers face while developing an antivirus is the fact software particularly operating systems are very complex. All it takes to create a vulnerability is for one programmer to misunder- stand the purpose or secondary effects of what some other pro- grammer has done (Yehoshua & Kosayev, 2021). This has nothing to do with the intelligence of the developer. If a vulnerability exists someone will find it. They don’t have to be smarter than the devel- oper. To ensure that the antivirus provides the needed protection, a developer must ensure that the program provides room for in- teraction with the users as that’s the only way to get some feed-

back that can help on enhancing the program's security.
