My company uses Trend Micro's antivirus software ("Client/Server Security Agent") on our PCs. When I tried to download the latest version of Messenger Plus, Trend Micro blocks it because it thinks it is dangerous:
Threat details: Verified fraudulent page or threat source.
I asked Trend Micro to reclassify but they still consider it to be a "Disease Vector." Just thought I would alert you in case you can do anything from your end.
(I have otherwise been able to install the latest version so I'm not waiting on a resolution.)
