There are flaws in Opera and Internet Explorer which could allow URL's in the address bar to be obfuscated. One of the safest approaches is to be wary of web links from unknown or untrusted sources. To quote....
Claudio "Sverx" has discovered a weakness in Opera and Internet Explorer, which can be exploited by malicious people to trick users into visiting a malicious website by obfuscating URLs displayed in the status bar.

This may cause a user to follow a link to a seemingly trusted website when in fact the browser opens a malicious website.
