What can be done to reduce the risks of your computers and network from receiving malware from malvertising sites? Here is a short list of what can be done now to reduce what computer security professionals call your “attack surface.”
1.If possible, uninstall Adobe Flash, Oracle Java, Microsoft Silverlight and other third-party browser extensions.
2.Keep Your Plug-ins Updated. Google Chrome automatically updates Adobe Flash, and so does Microsoft Edge. Internet Explorer on Windows 8, 8.1 and 10 automatically updates Flash, too. If you’re using Internet Explorer on Windows 7, Mozilla Firefox or Safari, ensure Adobe Flash is set to automatically update.
3.Keep web browsers updated. Web browsers should automatically update themselves.Don’t disable automatic updates!
4.Install Windows security updates as soon as they become available.
5.Install Windows 10.
6.Use Microsoft’s Enhanced Mitigation Experience Toolkit (EMET) or MalwareBytes Anti-Exploit (MalwareBytes is a little more user friendly). This software monitors your web browser and watches for techniques browser exploits use. If it notices such a technique, it will automatically stop it.
Remember, websites are hacked every day.If you are vulnerable, a single click can infect your system. By taking the steps outlined above, you will hopefully be a little more secure from the dangers of a site containing malware.
