Google search with IE11 and Google Chrome defaulting to Arabic

We have checked the system language and regional settings and it is set to US English.

do you mean Control Panel > Language of Windows 2016?

Yes.  Every possible place is set to US English, even using the browser settings.

it sounds like for some reason the imaging computer accessed Google in Arabic uisng both IE and Chrome. you may simply clear ALL history and cookies of both IE and Chrome, close both browsers, then open them again.

if only Google related pages keep showing Arabic, just change the language settings of your Google account.

I'll dole check the cache but as originally stated regarding Chrome, when using Google Chrome, ALL pages default to Arabic text and the only work around was to enable translation to English

Have you run anti virus and malware yet?
 I only ask because it's happening on 2 different programs.

forgot to mention that both IE and Chrome have their own language settings, please double check or simply reset everything to default for the two browsers.

Check public IP localization . If your provider is " seen " on an area (Arabic language for example), google will "default" to local IP localization language without no personal settings (no account mode), no matter what you have on SO level.
Solutions?
If your IP is on different language area, ask google to correct this. Or your provider, to bind IP class to the correct zone and/or correct the dynamic routing settings to route you to another "exit point" to Internet.
I have too little about issue. For sure it doesn't look like an OS problem, with the information that you post.
Little check: test it with an HBCD/Live Linux distro. If even in this case you found Arabic Google, is your public IP. If not ... we should investigate beyond.
