Malware infections are being caused by websites.

 Configuring prompting before downloading content will help prevent infections caused by Internet browsing. Prompting before downloading content is a browser setting that asks the user for confirmation or permission before downloading any file or program from a website. This setting can help prevent malware infections by allowing the user to check the source, type, and size of the file or program before downloading it. Prompting before downloading content can also help the user avoid unwanted or unnecessary downloads that may consume bandwidth or storage space. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 202.
