Every anti-virus collect informations..
Like all games, like Facebook, everything is connected
:watch_dogs:
The most important part on policys are
"etc.." and "other informations", like
"Other information required to improve Baidu Antivirus technology and services."
They collect some informations that they didn't want to tell to the user
All anti-virus does that. They will not capture your webcam or steal your accounts so it's not "really" important to be paranoïac for nothing ^^
After all, it's my opinion.
