Anant, how did this popup was added to your site?
Do use any third party plugins that might have done this?
Or may be you have made some kind custom code modification?
What is your site URL?

Now the popup is also there even when on splash screen. Mobile safari users can not even go to the site.

Sorry. I also added Anti-brute force and profile completion bar plugins

Anant, can your PM me your site URL?

Try disabling those plugins and see whether this helps.

Are you on free hosting or something?

The Popup is there even after disabling the plugins

There should be no problem on the computer as the problem with the website is there even when browsing through my android mobile and ipad.

And @Aliia i already messaged you.

anant i tried your website i got the message not to proceed with safari, on ipad i tried a different browser agreed i wasn't using safari and it kept taking me to gambling  apps, on my computer it opened a big new window to download mac keeper

so if your computer had a virus, root kit etc then only you would have this problem surely not every one else, i once had a browser virus that turned images and videos into ads on my site and other sites, but only i could see them and no one else ...........

have you added any links into your site that have messed and are causing these redirects,

This seems to be affecting ajax only. As far as I know the enter and leave buttons should be javascript or ajax. So this can happen because of how the server treats these languages?

This problem is also there while pressing the login button while using the site.

Anant, some kind of .js is being activated on your site on splash screeh. This .js refers to:

cdn.popcash.net/pop.js . This might or might not be the cause. Are you aware of any plugins or may be server settings, which require this script?

Can you check what you currently have in:

1.dnd_index.html ( ow_themes/yourthemenamehere/master_pages

general.html ( same place as dnd_index.html).

base_document_splash_screen.html ( ow_system_plugins/base/views/conrollers).

Anything suspicious in those files?

2. find text keys for "leave" and "enter" in admin panel>>settings>>language.

They should not contain any script/links. Should be just plain text.

3. Have you added any custom HTML widgets?

If you did, check whether they contain anything that should not have been there.

Anant, one more question. Who do you host with?

It seemed to be a server issue and I set up another site with a different host. The issue is not there.

am i correct in saying that hosting services cant do that especially a porn site as the site may be viewed by children 

Kieron, apparently this particular host thought that it is ok to put a redirect to porn site.

That was the problem I was having Kieron. So, I am setting up the website on another host by importing the database.

what was the hosting you were with 

i had this problem but was a plugin not server  well was not the plugin but what i put in the plugin
was advertisement plugin and was one of the imbed adds that was causing the popups on every dam page and even changed words to links to porn site
