Safety
The suite from Kingsoft is one product. The search ad is another.
Install from wps.com, Microsoft Store 9NSGM705MQWC, Play cn.wps.moffice_eng, or App Store id1491101673. A banner that says free full setup is how laptops get a second payload. This site is an independent handbook and is not affiliated with Kingsoft Office Software Corporation Limited.

Publisher line
Kingsoft Office Software Corporation Limited is the name that should appear. Look-alike publishers are a stop. Updates should come from the same channel you used to install, not from a toast that opens a random domain.
Ads inside the real app
Annoying banners in a signed Kingsoft build are not the same as a trojanized installer. Quiet them in settings or pay. Do not fetch an “ads killer.”
Updates
Updates should come from the same channel you used to install, not from a toast that opens a random domain. Store installs update through the Store. Website installs update through Kingsoft’s updater or a fresh vendor download.
If you already slipped
If you already ran a mystery EXE, that is an incident: disconnect if you can, uninstall strangers, then reinstall from official channels. Changing a Kingsoft password on a phish page is how Cloud files walk away.
