In Windows, the highest-level user is the administrative user. In Linux, the highest-level user is the root user. A rootkit, named after the root user, modifies the kernel of the operating system. It goes on the lowest level of the OS so it can avoid anti-malware software. Since it's built into the kernel of the OS itself, the task manager will not see it. Rootkits are often combined with additional software, which results in malware that is difficult to remove. The best solution is a rootkit remover. Also, a computer that has a UEFI BIOS with secure boot may be able to prevent a rootkit from installing into the kernel. Keyloggers watch and record user keystrokes. Since the keyboard is a major (often primary) input method, this is an effective way to subvert encryption methods. Keyloggers can also store screenshot and clipboard information. Keylogger data can be perused by hackers at their convenience. Luckily, keyloggers are usually installed as a piece of well-known malware, so updated anti-malware can stop it from even executing. Adware and spyware are some of the most common malware. One very lucrative way to make money on the Internet is to display advertising. One way this occurs is by installing adware. Once the adware begins executing, it begins popping up ads and slowing down performance. Sometimes, adware is installed along with another, more innocuous software. One challenge with removing adware is knowing who can trust when it comes to removal of adware. Adware often presents removal tools which only add more adware. Another type of malicious software is spyware. Spyware watches what users do and use that information for identity theft and more. It often tricks users into installing it by posing as fake security software or piggybacking on peer-to-peer software. Adware and spyware are a large percentage of malware. Time, attention, and bandwith are valuable to those who install this malware. They can mine for cryptocurrency, raise advertising revenue, and steal bank information.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
