How to prevent your Windows clipboard is stolen

Unfortunately, some webpages can steal the text you last copied for pasting (copy & paste) in Windows. With a combination of JavaScript, ASP, PHP or CGI, those webpages may be able to write your possible sensitive data (like your credit card number) to a database on another server.

An example of this is available here.

Fortunately, the fix for this is quite simple:

1. In Internet Explorer, go to Tools -> Internet Options -> Security
2. Click on Custom Level
3. In the security settings, click to Disable the “Allow Paste Operations via Script.” That will keep your clipboard contents private !
