Browser Test: Reader Sees Weird Result

I wanted to check if my version of Internet Explorer was vulnerable to the security problem you described in your March column. I clicked the link at Secunia's Web site to run the test you suggested, but my McAfee Anti-Virus program said it had found and deleted a Trojan horse. Was that supposed to happen?

Bugs and Fixes responds: Don't worry. There is no Trojan horse program hiding in Secunia's test code. The test checks your browser to see if it can be fooled by a phony site masquerading as the valid site. Secunia's test attempts to get your version of IE to display a false URL, something a Trojan horse site might try, but the test poses no threat. If Secunia's test shows that your browser is vulnerable to URL spoofing, go to get Microsoft's cumulative update (numbered 824145).
