since some viruses attacked my colleague pc she can't access her hard drive from 'my computer' anymore. (my computer --> 2x click H : / ....)
but she can access it through drop down address bar (eg. H : / ....).
whenever she 2x click H : / .... from 'my computer', the "open with..." dialog comes out.
how to correct this problem?

Check in "My Computer" -> "Tools" -> "Folder Options" and see if Single Click has been enabled, if it is re-enable Double Click; if not post back with the version of Windows and the name of the Virus found.
