Microsoft has confirmed that an unpatched Internet Explorer
vulnerability makes it potentially dangerous to press F1 if you are
running earlier versions of Windows.

A security bug in the VBScript technology bundled with Internet
Explorer means that it might be possible to create a web site that
displays a specially crafted dialog box that pushes malware providing
a victim is tricked into pressing the F1 (help menu) key while viewing
a booby-trapped site using Internet Explorer. The novel exploit
technique works on older versions of Windows (Win 2000, XP and Server
2003). As previously reported, Vista, Windows 7 and Windows Server
2008 are immune.

Linux has been quite immune for some time.
