False warnings with Joomla mootools-core.js.

I have three sites built using Joomla. Two of those sites are the most recent version and fully patched. However, all Trend Micro Toolbar (I use Chrome) flags a specific java script file on all three as being dangerous and blocks the website.


When I first received this error, I thought that I had really be compromised and infected. However, after receiving this same error an all three sites, I started to think that this is a false alarm. Also, I check my webmaster tools on Google, and Google said there is no issue with any of my sites.

It appears to me, that the latest update from Trend Micro must have included this file is causing the issue. How can I tell that this is really an issue, and not a false flag? If it is a false flag, how can I remove the file from the list? I don't want to put a blanket exception in the exception list, because what if my sites do get compromised I would like to keep have a true warning, not a false one. How can I resolve this issue?

Thank you.

Hi Daryl,

Many apologies again for taking a long time to fix the JavaScript issue. We were informed by our product development team that the fix of this issue is included in the latest pattern file. Please follow the steps below to apply the update:

  1.  Remove related URLs from the Exception List. (if you've added them to the Exception List)
  2.  Right-click on the Trend Micro system tray icon.
  3.  Click Check for Program Updates, then The About Your Software windows will appear and will automatically check for available updates.

After update completed, please verify all websites which had blocking issues and please do let us know if the solution works for you. One challenge is that your website users using Trend Micro would have to do this also, but our software and patterns auto updates periodically, so hopefully their Trend Micro Security installs will be updated soon as well.

Thank you.
