Experts warn of “drive-by” downloads – software that gets downloaded to your computer from an Internet site without your knowledge. What’s the best way to prevent it?

  1. Watch the indicator light on your modem. If its starts to flash or blink, someone may be trying to send you unwanted software.

  2. Surf fast. If you do not linger on any one page for more than a few seconds, you can reduce your risk of drive-by downloads

  3. Make sure that the security setting for your browser is high enough to detect unauthorized downloads (for eg: atleast the medium setting in Internet Explorer). Also make sure that you have installed the most recent version of the browser software.

  4. None of the above

Browser security settings are the primary defense against drive-by downloads. Setting your browser to at least 'medium' high security helps detect and block unauthorized downloads. Keeping browser software updated ensures you have the latest security patches. Modem indicator lights and surfing speed are not related to security.
