Which is the best description of a computer virus?
MatroZZZ [7]
The best description of a computer virus is. Someone first starts out making a malicious program, then can send it to a unexpected user. After that, when the user opens the malicious program, it can do negative things on the target. The virus first starts out in the system32, then infects a random file type for example, exe files, or dlls etc. Then random errors can pop up on the computer saying "YOUR COMPUTER IS UNDER RISK! CALL THIS NUMBER NOW! 555-555-5555" and the options of the error, can direct you to a website, that can give you another virus. To get rid of a virus, you have to ignore the popups that comes onto your computer, and get a strong antivirus like avast, or avg. Then let it scan the system. After when the scan is done, it will show up the virus, and it will give you options "to delete virus or ignore it" you would hit delete. I hope this answer helped you. Let me know if you have any more questions! Thanks!

kate decides to download an extension to her favorite browser to quickly store links on her spreadsheet software. while download
uranmaximum [27]

By ignoring the opt-out check box that allows the extension to download a search toolbar, the error which has occurred here is that: d. Kate has installed a potentially unwanted program (PUP).

<h3>What is a software?</h3>

A software can be defined as a set of executable instructions that is typically used to instruct a computer system on how to perform a specific task (function) and proffer solutions to a particular problem.

<h3>What is a potentially unwanted program (PUP)?</h3>

A potentially unwanted program (PUP) can be defined as a piece of software that's bundled into download packages and may be unwanted by the end user because it offers no benefits or may pose high risk.

In this scenario, we can reasonably infer and logically deduce that the error which has occurred here is that Kate has installed a potentially unwanted program (PUP) because she ignored the opt-out check box which then allowed the extension to download a search toolbar.
