How do computer viruses work?
The most common type of computer virus is the boot virus. This virus infects the master boot record (MBR), which is the first sector of a hard disk. The MBR contains the boot loader, which is responsible for loading the operating system.
When the computer is turned on, the boot virus infects the MBR and copies itself into the RAM. From there, it can infect other files and programs on the computer. It can also spread to other computers on the network.
There are other types of viruses, including file infectors, macro viruses, and logic bombs. File infectors infect executable files, such as .exe and .com files. Macro viruses infect files that contain macro code, such as Microsoft Word documents. Logic bombs are programs that are programmed to do something malicious when certain conditions are met, such as a certain date or time.
Most viruses are created to do harm, such as deleting files, stealing information, or causing the computer to crash. However, some viruses are created for more benign purposes, such as displaying a message or joke.
Computer viruses are spread in a variety of ways, including email attachments, infected websites, and infected removable media, such as USB drives. Once a computer is infected with a virus, it can spread the virus to other computers. Therefore, it is important to have antivirus software installed on your computer and to scan your computer regularly for viruses. Click Here
How computer viruses spread and how they are prevented
A computer virus is a code or program that is designed to copy itself and spread itself to other computers. The most common way for a virus to spread is through email attachments or by sharing infected files with other people. A virus can also spread through websites that have been hacked, or through social networking sites like Facebook and Twitter.
Most viruses are harmless, but some can cause serious damage to your computer. Viruses can delete files, corrupt data, and even damage hardware. In some cases, viruses can allow criminals to gain control of your computer and use it to commit crimes.
There are many ways to prevent viruses from infecting your computer. The best way is to install an antivirus program and keep it up-to-date. Antivirus programs detect and remove viruses from your computer. You should also be careful about what you download from the Internet and only download files from trusted sources.
You can also help to prevent viruses from spreading by not opening email attachments from people you don’t know, and by not sharing files with other people unless you are sure they are safe.
