Como se dice Free Antivirus Software
 

Hello! I am working late tonight and have hit a snag. I'm organizing anti-virus software by the company that makes it (AVG, Norton, etc), and I can't think how to refer to this means of organization... maybe because I'm having trouble saying it in English! :) What I'd like to say in Spanish is the equivalent to "Free Anti-Virus Software by _________." I'm trying to think whether in English, I'd say "Free Anti-Virus Software by Brand," or "...by maker," or "by company..." But, regardless of what it should be in English, can someone please tell me how to express this in Spanish?
Thanks very much!

Software antivirus gratuito de ....

Rusty, could you use por in place of de?

I think the preposition de shows ownership in this case. If you wanted to add a time frame, you could say ... gratuito por un mes.

What you quoted "gratuito por un mes." is correct.

In this case is has to be "por".

Consider this: "Esto es concedido por ..."


Hernan.

I would can think in this phrase for you.

Libre antivirus por un periodo prueba.

Free Antivirus software trial period.

It was my suggest above it.

Free is not said libre when speaking about price. :)

Thank you all for your suggestions! I see that I did not pose my question very well at all -- I'm sorry! I'm looking for the appropriate Spanish to complete the "blank" in my post: The part in Spanish I already have is "Software Anti Virus Gratis ____________________." What I can't get is how to say the Spanish equivalent of "by brand," or "by maker," or "by company" -- or whatever it is that a native speaker of Spanish would say when referring to software that is organized in such a way. Thanks again, in advance, for your assistance.

Oh!

Software Antivirus Gratis por Marca (Brand)
Software Antivirus Gratis por Fabricante (Maker)
Software Antivirus Gratis por Empresa/Compañía (Company)

Thanks so much!! Which of these phrases do you think Spanish speakers actually would use when putting software into groups such as AVG, Norton, Panda, and so on?
