Why does avast report wps danger?

I downloaded the wps from the official website. https://www.wps.com/
Wps is a very common office software and I have used other versions before.
Why the new version from official website is dangerous reported by avast?
Avast shows IDP.ALEXA.51, Can Avast give more details?

Can Avast give more details?

Man, I was hoping this was WPS WiFi - always a good time!

Avast! should be fairly quick to clear up common apps being detected. I’ll MD Milos and see if he can swing by.

I want to report a false positive (select file or website)

but the Wps installation package compressed file over 50m.

What other methods can I give feedback?

Morning Chenstar,

Sorry that I lost you in the thread. Avast! can also be reached via email: virus@avast.com

However, please be aware that I had previously DM’d Milos regarding this thread. Milos belongs to the Avast! team who deals with this kind of information, and/or will pass it along to the appropriate people.

Hello,
post the screenshot with detection to see which file is detected, please.
Report i through https://www.avast.com/false-positive-file-form.php if the file is too big you can put a link to download or upload it to our ftp (https://support.avast.com/article/FTP-file-upload) and let us know (through the mentioned form) the uploaded filename.
