Highjacked or Hijacked ?

[ErikAlbert]

English isn't my first language.
I see a post with the title "Highjacked??" of somebody who has malware-problems.
Is this a spelling error of the word "Hijacked" or does it mean something else, like being hijacked high in the sky, a sort of combination of two existing words in one new word ?

Both forms are allowed: http://en.wiktionary.org/wiki/hijack

Generally you'll find hijack in far greater use.

The Oxford English Dictionary (2nd Ed), shows "hijack" or "hi-jack" as the current forms, and "highjack" as the obsolete original form.
