Answer(s):
What is a computer virus and what is the way to prevent it? Computer viruses are very much like the Flu virus of the real world. A computer virus is designed so that it can clone itself and copy from one computer to another. Computer virus spreads to different computers via a file or document. Simply put, computer viruses are software or programs that are created or written to harm a computer. It infects itself with files and documents of the infected computer, so it can be easily spread to other computers. The basic function of most computer viruses is to erase the computer's files and, in some cases, delete them completely. How does a computer virus attack? Programmers of computer viruses open the file or software to anyone by attaching a file or software to the virus they have created. The virus is spread to various computers through that file or software. Computer virus enters the computer but cannot start working. It has to wait until the user runs the affected software or file. The virus starts working on its own as soon as the affected file is run. When the virus is executed on the computer, it infects itself with various files on the computer, thus spreading it through those files. Even some viruses can spread to other computers on the network of the affected computer. Computer virus basically corrupts files on a computer, deletes files, steals saved passwords in the browser, steals data, tracks keyboards, spamming email contacts and so on. Even some viruses can cause permanent damage to the hard disk. How to spread the computer virus? In the modern computing world, there are many ways to spread computer viruses. For example, email, message attachments, internet file downloads, social media scam links, etc. Moreover, the virus is spread on mobile phones through third party applications on smartphones. Currently, the most popular means of spreading the virus is social media. The virus spreads by disguising things like fun images, greeting cards, audio, video, etc. How to protect yourself from computer viruses? As I said earlier, the computer virus is very much like the real world virus. It can take some form of horror at times. A little computer virus can end up deleting your very important documents. So you have to be very careful to be safe from computer viruses. Use anti-virus programs on your computer. There are many good anti-virus programs available for free. Use any one. Do not open email attachments, message attachments, links sent by anyone other than a known person. Do not download and install nonsense software from the Internet. In this case you can install the software from Appstore. Appstore is available on all operating systems and all software is virus free. Computer viruses are just one type of malware. Antivirus can never fully protect a computer. This requires the most user awareness. Answered by AL MaMun (4 Golds) Thursday, 21 Nov 2019, 04:29 PM |
