Please describe measures to prevent computer viruses and how to remove them.

Effective ways to prevent your computer from being infected with viruses: Don't open suspicious email attachments, view emails in plain text, be aware of viruses, watch out for suspicious links and hyperlinks, and don't buy from pirated or untrusted emails.

1. Don't open suspicious email attachments.

This is the most common way to infect your data and computer, for example, if you receive an email from an unknown address with suspicious files. First of all, don't open it in a hurry, don't ** or run the files contained in this email if you open it accidentally, if you want to open such attachments, it's best to scan them before opening them.

2. View emails in plain text.

To prevent your emails from becoming infected with viruses, turn on email SMS alerts so you can view and read all your emails in plain text instead of email. When you open a malicious slag file in plain text, your computer won't be infected with viruses.

3. Pay attention to viruses**.

There are several chain-spreading viruses on the Internet, which contain viruses whose owners require that a virus be sent and alerted to all known eligibility people, and that as soon as someone opens it, your computer will be infected with the virus.

4. Watch out for suspicious links and hyperlinks.

Links and hyperlinks are also an easy way to infect someone with a virus, and if you receive a suspicious link that doesn't start with www, or contains suspicious terms, don't open it. Similarly, don't open a suspicious hyperlink or file if it contains it, both of which can cause your computer to be infected with a virus.

There are many pirated copies on the Internet**, which you can get free of**, and these sites transfer viruses to your computer along with the files. Viruses from pirated versions** can corrupt data or infect your computer with annoying pop-up ads.

Patch the system in a timely manner and set a secure password.

If you don't have virus protection software installed on your machine, you'd better install one. If you're a family or an individual user, it's fairly easy to get any of the best ranked programs.

A computer virus refers to a set of computer instructions or programs inserted into a computer program by the compiler that destroy computer functions or destroy data, affect the normal use of the computer, and can replicate itself. Computer viruses are infectious, hidden, infectious, latent, excitable, expressive, or destructive. Life Cycle of a Computer Virus:

Development Period, Infectious Period, Incubation Period, Attack Period, Discovery Period, Digestion Period, Extinction Period. A computer virus is a program that is artificially created, destructive, contagious, and latent in that can destruct computer information or systems. It does not stand on its own, but is hidden within other executable programs.

When a virus is found in a computer, it will affect the running speed of the machine at least and crash and destroy the system. Therefore, viruses bring a lot of losses to users, and usually, we call such destructive programs computer viruses. Computer viruses can be classified into three types: bootstrap viruses, file viruses and mixed viruses.

According to the link method, it can be divided into three types: source code virus, embedded virus, and operating system virus. According to the system classification of computer virus attack, it is divided into viruses attacking DOS system, attacking Windows system viruses, and attacking UNIX system. Today's computer viruses are constantly evolving, including some unique new viruses that cannot be classified according to regular types, such as Internet viruses (which spread through the network, and some data carrying viruses is increasing), email viruses, etc.

The correct way to effectively prevent your computer from being infected with viruses is:

The measure that cannot prevent the computer from being infected with viruses is not to use a USB flash drive.

A common feature of computer viruses: a contaminated program is capable of delivering virus vectors. When you see that virus vectors appear to be just words and images, they may have destroyed files, reformatted your hard drive, or caused other types of disasters.

If a virus doesn't inhabit a contaminating program, it can still cause you problems by taking up storage space and degrading your computer's overall performance. For example, some viruses release a lot of junk files and take up hard drive resources. There are also viruses that run multiple processes, making the infected computer very slow.
