Directory permissions

You need to check if Magento’s directory permissions are set to how it is suppose to be for specific structure. None of your directories and files should be having public access or 777 permissions.

Only “media” and “var” directories on your Magento root should have 755 permissions for images, cache and session purposes.

Remove unknown Javascripts

Check your web pages for unknown javascripts and codes being called in header and footer.

Go to your Magento admin configuration and make sure those don’t have unwanted scripts in them. Follow below paths in admin: System -> Configuration -> Design -> HTML Head -> Miscellaneous Scripts.

Third party resources

Next part you want to check is third party resources which are being loaded on your website front pages.

If you find such request then note down its details and consult your hosting provider to notify about it and get it removed or blocked.

To find such malwares first you will require all the files and database on your computer. After that make a search operation on your store’s files to search for specific keywords like “eval”, “urlencode”, “urldecode” and “md5” which can be used to run the malware scripts. From the search results note down the files which shows occurrence of those keywords. You can try to search the request from above step as well if you found any.

When you have that files identified then you can compare those with default Magento files and structure to make sure if they are malicious codes or not.

You can find Magento’s all files on specific version from here https://magento.com/tech-resources/download/. Follow same search process on the database but you will require another tool for search operation on it as normal search tools doesn’t support that.
