On Google chrome i got one of my site blocked, which uses PHP. Here is the screen shot
and my Kaspersky blocked one
This Trojan is coming normally from the files uploaded from the affected machines. And this will work only if the file is having write permission. So the best method to avoid this is to remove write permission to all PHP, JavaScript and html files.
if you are already affected with this, have a search for the iframe which is inserted in the files, index.php and index.html are the common files it is affecting, but there is a chance that it may affected other files too. You will have to edit all these affected files.
i haven’t heard this Trojan affected any websites working on Microsoft technologies.
