What Is WPS Office Expansion Tool?

Dear Computer Lady,

About once a week this appears, blocks out everything else no matter what I’m doing on the computer:

User Account Control
Do you want the following program to make changes to this computer
Program Name: WPS office expansion tool
verified publisher: Zhubai Kingsoft Office Software Co. Ltd
File Origin: Hard drive on this computer
yes no
Change when notifications appear

I will say no or x out but it keeps coming back & I have no idea what it is.

Thank You, Vicki

Dear Vicki,

It looks like you have been infected with some malware.

Kingsoft WPS Office is a Chinese program that is supposed to be a substitute for Microsoft Office, but it is often installed on a computer without your permission along with a program that you might have been trying to install.

I would answer “No” to the program making changes to your computer, and as soon as you can, get your computer cleaned out. Usually if you have one PUP (potentially unwanted program) malware, you are also infected with quite a few others.

If you live in the area, let me know and we can schedule a time for you to bring your computer in for a good clean-up.
