Virus doesn't appear to be very Spanish as in Mi ordenador tiene un virus.

But many Spanish words relating to the internet use the English equivalents - and this seems to be the case even where there are equvalents in Spanish. (With different prononunciation).

Some translations are literal. E.g. congelar 'to freeze', bloquear 'to block or to jam'.
