Explorer makes it possible for malicious users to craft code that would produce a fake Windows help file.
Specifically, if users come across a Web site that appears to have a Windows dialogue box that says to press F1, they should direct away from the site. Pressing F1 could lead to the execution of computer-disabling processes. A researcher who found the bug calls it a \"logic flaw\". It allows hackers to legitimately disguise the hack as a Windows help file.
