Dear Amy: Why do search engines sometimes pop up with viruses? — Drew, Plantation, Fla.
Dear Drew: Not every place on the Web is safe, and some sites listed in search engine results are infected with viruses or spyware. Most search engines cannot tell if a site is dangerous, but Google flags malicious sites and will warn users if they attempt to visit an infected website. Although these warnings can be helpful, they aren’t foolproof. You should always have antivirus software on your computer.
Computers that are infected with a virus might do weird things like redirect the browser when searching from a toolbar, or bombard the user with unwanted pop-ups. If your computer is behaving strangely, be sure to do a virus scan right away and run scans regularly to keep your computer safe. You can download free antivirus software from Comodo, comodo.com/products/free-products.php, or AVG, free.avg.com.
Following simple rules, such as never opening emails from people you don’t know and downloading files only from trusted sites, can help prevent viruses. To learn more about viruses and spyware, visit computerhope.com/issues/
