Since they spread rapidly, we may use our computer and the Internet consistently before realizing our system has a virus. In order to prevent your computer from catching a virus, it's important to understand how viruses spread.
So, how does a computer catch a virus? If you receive any type of spam email, a random download or pop up advertisement saying to "click here," these more than likely contain a virus. And these viruses spread by clicking on the link or downloading the file. If you ever encounter any of these circumstances, don't click on the link or open the document. Be sure to exit out of the display immediately. Also, your computer can receive a virus that's embedded in an HTML code on a website, through a software package due to security holes, from an infected floppy disk or sharing files over the Internet.
Viruses can cause major damage to a computer. They delete files, replace a computer's coding, erase your hard disk and can even cause your system to crash. That's why it's important to add protective measures to your computer to prevent a virus from infecting your system. Anti virussoftware scans files and your computer's memory to detect any patterns that may potentially be viruses. This software also has programs that can scan files before they are opened. Also, to make the virus scanning process easier, you can create automatic updates, allowing your computer to run a virus scan on its own. Be sure to let the scan to run completely and delete any viruses found.
