Hi @AllMediaLab
Pinegrow setup is clean from viruses and what you describe (warning, multiple messages and so on) may happen sometimes, particularly when we release a new version.
We do our best to contact AV developers but unfortunately, this is not that simple and with our regular updates, this is a never ending story …
There is a good old post about this situation : http://blog.nirsoft.net/2009/05/17/antivirus-companies-cause-a-big-headache-to-small-developers/
By the way, even if it’s a “false positive”, thanks for your report!
Best regards.
