Sourceforge pidgin download page blocked by google chrome as malicious

Guys,

if I may, that's the binary file (Pidgin-2.10.11.exe) that was downloaded
that seems to get blocked (in fact, local detection of malicious files by
browser itself).

Here is an example of such an alert with a Chrome derivative browser
(Dragon):

Despite my efforts, I could not reproduce any scenario where this was the
download URL that was blocked, therefore I believe this is a file-based
detection.

Now if you really look at VirusTotal, the Pidgin installer is not supposed
to be fully clean:

- Rising AV repots it as PE:Trojan.Win32.Generic.141A9A33!337287731
- Clam AV detects it as PUA
- Symantec reputation reports a suspicious.insight

This might be due to a detection of screen capture capability (look at
Zemana results), but can't be sure right now, just thinking out loud.
Anyway, I would try to report this to Google, as a potential FP.

My 2 cents,
