How do computer viruses spread and how can I protect my computer from them?
Computer viruses spread in a variety of ways, including through email attachments, removable media such as USB drives, and downloads from websites. They can also spread through malicious advertisements, or “malvertising,” which are online ads that contain embedded code that can install a virus on your computer if you click on them. Once a virus is on your computer, it can spread to other computers on your network, or to anyone you exchange emails with.
Some viruses are designed to spread quickly and cause damage, while others are created to steal sensitive information or to take control of your computer. The best way to protect your computer from viruses is to install antivirus software and keep it up-to-date. Antivirus software will detect and remove most viruses, but it’s important to remember that no software can protect your computer completely.
You can also help protect your computer by being careful about what you click on and download. Don’t open email attachments from people you don’t know, and be cautious about downloading files from websites. It’s also a good idea to back up your important files regularly, in case you need to restore your computer after a virus attack.
What is a computer virus?
A virus is a small malicious program that is able to replicate itself and spread to other computers. A virus can be spread in a number of ways, including email attachments, USB drives, and downloads from the internet. A virus typically causes either malicious or disruptive behavior on a infected computer, such as deleting files, stealing confidential information, or displaying unwanted advertising.
Most viruses are designed to harm the computer by corrupting files or causing the computer to malfunction. However, there are also some viruses that are designed to simply cause annoyance, such as displaying pop-up windows or sending spam emails. In some cases, a virus can even be used to gain access to a computer’s confidential information, such as passwords or credit card numbers.
The best way to protect your computer from viruses 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 open email attachments from people you know.
