Magento-1.9 mage.js file issue with Google Adwords

[rahul_patel]

I am new to Magento and here I am facing issue with Google AdWords.
There is a script file which is causing the issue  <script>https://magentocore.net/mage/mage.js</script>

when I am running in local this script file is not coming but in the server, this file is coming in all the pages.
I checked my project but didn't find the mage.js file and have no idea where it is coming from
Please guide me on this ...
any help would be appreciated, thanks in advance ...

That doesn't sound like a regular file. If you can't find it in the filesystem, I would recommend checking the miscelllaneous scripts section of configuration:

Did you get rid of the problem? Got the same problem with a website of my client, unfortunately we are not the webmaster - so I have no clue what to recommend my client. Would appreciate some advice.

You have found the MagentoCore.net skimmer, which is the most widespread identity and card skimmer to date. See my blog for specific recovery instructions. NB MagentoCore includes a backdoor that will reopen admin access for the perpetrators.
