Data Execution Prevention is a very handy feature if you routinely surf in the shadier side of the internet. It can help stop the spread of spyware or virus attacks, but unfortunately for Internet Explorer 7 users who are running Microsoft Windows Vista, it’s disabled by default. To enable Data Execution Prevention load up internet properties (start IE7 then go to “Tools” -> “Internet Options“) then click the “Advanced” tab and scroll to the “Security” section. There you should find the “Enable memory protection to help mitigate online attacks” checkbox. Check it, then click the OK button. Once that’s done you’ll have an extra layer of security when browsing the internet.
