avast! Free Antivirus 2014.9.0.2007
Although my OS is English and I should have avast! English installed I’m seeing two languages in some windows. For instance:

I’m seeing Dutch and English. I had the same problem in 2014.9.0.2006.
It is the same with Pirate talk.
It looks like they forgot to translate quiet a lot of things or that avast isn’t always looking at the correct language file.
Some parts of the interface are online content. They’re being updated. It takes time…
Not all of the languages have finished the translation… Please, be good with the hard work of the free translators 
Will do. Tnx for the explanation.
Hello! I have free version of antivirus and English language is installed in setting but I see some screens in other language I do not understand. I wrote to support on 8th Dec and no help yet. Do not say they did not translate in English!

There are two situations:
Thank you for the answer! I installed Avast with English only and I see some screens with other languages… Will I see them if I get Pro Antivirus? I want to have only English screens == Regards =Larisa
The translations are available in all avast! versions. They do not depend if you have the free or paid versions.
Same here, with their Christmas Discount Offer.
Besides, the offer makes no sense, quote (translated):
“Upgraded license for the remaining 92 days - normal price 699, now 149, save 769”
Besides, if this is only for the remaining 92 days it’s not a deal, it’s a rip-off. 
And I’m on a 3 computer / 2 year subscription btw, so I can’t use this for anything.
I think they need to redo this one…
Thank you again! I only do not need translations but pure English version as it s in my Settings. Why do they show me other languages? I have reinstalled avast and nothing has changed… so sad so sad
Are you in an enghish speaking country right now? Are you connecting to internet through a proxy (or Tor)? If so, you can see local content (and offers) in other languages.
Hi! I am not in English speaking country. I have English version of Windows and it never shows me other language interface. In Avast! I have only English installed and I wonder why I see language I do not understand. If I visit Norway - will I see UI in Norwegian? Hungaian in Hungary? Avast is not for travellers… I did not have any help with this… Thank you any way.
Forgot to say - no proxy!
Some parts of the interface are online content. The offers, prices, etc. must be of a shop near the corner. And then you could see something in a different currency and language. Can you post a screenshot of this particular window you’re seeing in non-English?
Hello again! May be you are right and they show me local currency but when I click “upgrade” I see perfect English screen with dollar prices. OK. I am attaching screenshots and look - they show 2 different currencies of 2 different countries and not dollars. Some pages do not have currency. Slavic languages are different too. I will not fight for languages any more…
Thank you for your attention. Larisa
Larisa, thanks for reporting. I’ll need igor help here (but I’m not sure if he is on Christmas vacation).
Thank you again! It s OK. I have decided to stop writing about these issues or not issues. == Larisa
