Dear Users,

We have stumbled upon an issue with Google Safe Browsing which flagged our website as "malicious". After a number of false positive reports and questions from our side, we finally got an answer. As it turns out, Free Download Manager is supposedly practicing "aggressive" installation of the Chrome plugin in certain new versions of our installer. We found it to be very odd because we did follow their guidelines. Nevertheless, we are working to resolve the issue, although it is very unusual and unclear.

It's not necessary about FDM plugin for Chrome.
There may be some adware software reported which is available

on http://www.freedownloadmanager.org/download/
or http://en.freedownloadmanager.org/Windows-PC/

There were already similar reports in the past.

From Google Webmaster Tools (WMT), we can see that they block certain URLs. For example, when we put FDM 5 installer here, they blocked the whole /fdm5 folder, so that files2.freedownloadmanager.org/fdm5/any_url_here is blocked now in Chrome. The same thing with /rc folder (v3.9.5 RC was there).

But no URLs from FDM library (that you mentioned) did not appear there, and were not blocked. Needless to say, all files on FDM servers are being constantly checked with different antiviruses, and are clean on VirusTotal.

Is something new about this case?
