What are computer viruses and how do they spread?
A computer virus is malicious code that propagates by making copies of itself and infecting other computers. A virus might corrupt or delete data, use an email program to spread itself to other computers, or even hijack your entire system, causing it to send emails or show advertising on your behalf.
Viruses are often spread by email attachments or by downloading infected files from the internet. Once a virus is on your computer, it can spread to other computers on your network. Because of this, it’s important to have a good antivirus program installed and to keep it up to date.
Most antivirus programs can detect and remove viruses, but they can’t always repair the damage they’ve done. That’s why it’s important to back up your data regularly, so you can restore it if your computer gets infected.
How do computer viruses spread and infect computers?
Computer viruses spread and infect computers in a variety of ways. The most common method is through email attachments. When you open an email attachment from an unknown sender, you are opening the door for a virus to enter your computer. Other common methods include downloading infected files from the internet, installing infected software, and sharing infected files with others. Viruses can also spread through social networking sites and instant messaging programs. To protect your computer from viruses, be sure to install anti-virus software and keep it up-to-date.
