Computer viruses are usually spread through email, by sharing files, or on disks.

How does an antivirus work?
Antivirus software, sometimes known as anti-malware software, is designed to detect, prevent and take action to disarm or remove malicious software from your computer such as viruses, worms and Trojan horses. It may also prevent or remove unwanted spyware and adware in addition to other types of malicious programs.

Answering a question by David:
What is the difference between computer virus and computer worms

Some differences of the two
Infecting a Computer- virus inserts itself into a file or executable program. Worm exploits a weakness in an application or operating system by replicating itself.

Infecting Files- virus deletes or modifies files. Sometimes a virus also changes the location of files. Worms usually only monopolize the CPU and memory.

Speed- virus is slower than worm.
E.g.The code red worm affected 3 lack PCs in just 14 Hrs.

Definition- The virus is the program code that attaches itself to application program and when application program run it runs along with it. The worm is code that replicate itself in order to consume resources to bring it down.

You have to know the definition of the virus, its effects in your computer, its importance, how to avoid it, and how to remove it

It is better to have multiple antivirus apps in terms of antivirus capabilities, but you must not use them at the same time as they do not play well with each other. You can have multiple antivirus but decide only one antivirus that has the widest "scope" of virus search, then let the others run when needed

Answering to a question by ezravagant:
Why do people write viruses and other destructive software?

Viruses and other destructive softwares are best to steal important and condfidential informations from others. With these they can use the gathered information for whatever they want to use it( stalking, stealing, estafa).

But viruses are also used by the government. At the cold war and maybe until now, millions of confidential files have been stolen from different countries by their enemy country. Top secret military operations and tactics were found by hackers and they had sold those to the government of the enemy of the country that originally has the information. Some government also hire hackers to attack or track other hackers and criminals.

Answering to a statement by ezravagant:
What to do if you suspect your computer is infected

Don't get near it and remember to aim for the head. Lol.
Real answer:
You should either isolate the file or delete it or simply fix it with an anti virus app. After that re scan your computer to make sure that it is free from viruses.
You can also ask for help to the internet or other people who know how to do it. Or maybe ask in this forum

What if a third-party antivirus is actually a larger virus that competes and destroys other virus, infecting your PC with a much larger and possibly impenetrable virus? Is it possible?

If you think your computer has a virus,what is a good first step in solving the problem?

Whether you saw a message saying a virus was detected, or your computer just seems slow and unreliable, you’ll want to scan for malware on your PC and remove any you find. Here’s how to clean your PC of viruses and malware.

While many viruses and other types of malware are designed simply to cause chaos, more and more malware is created by organized crime to steal credit card numbers, online banking credentials, and other sensitive data. The typical old-school viruses aren’t a real problem. The problem now is ransomware and spyware, and that requires new tools, and new techniques.

It's possible to use an antivirus without on-access scanning, but this generally isn't a good idea – viruses that exploit security holes in programs wouldn't be caught by the scanner. After a virus has infected your system, it's much harder to remove.

you can simply go to your file manager, select the drive that you think's infected, and then click "view" and tick "show hidden items" now go search for a file that has a .Js extension in it and delete it.

you can actually run 2 at a time but they won't work as expected. Here the things that might happen:
1) they will try to kill each other
2) they will fight over viruses
3) and they will bog down your computer, utilize your processing power, ram, and will also use "virtualization" which will make the use of applications that require it to run smoothly a nightmare.

turn on Windows defender or install third party anti-virus so that it will notify you when there's a malicious program/file that may break your OS.

you should know what is a "virus", how do you get it and also get rid of it.

In order to prevent infection, simply turn on Windows defender or install third party anti-virus but the best thing to do is be careful when downloading contents from the internet and visiting websites.

Open Action Center by clicking the Start button. ...
Click the arrow button next to Security to expand the section.
If Windows can detect your antivirus software, it will be listed under Virus protection.

Every antivirus has many features which can be broadly categorized in to two parts - On demand features and on access (real time) features.
On demand features needs user actions to start/stop it's working. Whereas real time features such as real time file scanning, or automatic memory scanning are always running in the system.
If you use two antivirus software with all real time features enabled, the similar features from both antivirus software will conflict with each other and may not work properly resulting in to a very bad user experience. Also these real time features will consume lot of memory and will slow down your system drastically.
By disabling the real time features from one of the software, one can use only on demand features such as initiating full system scan manually. However for general public, it is very tedious task with very low success rate.
Hence it's a bad and painful idea to use two antivirus software at the same time.
