App manager - Infection or what is this?

I have been getting a delayed Pop-Up that is called “Apps manager” and it shows “twitter and Weibo” "update buttons and it will only close but it won’t show up in “Programs and Features” or in any other startup folders, and it’s not showing up in the registery that I’ve found any where and I did google it and there is virtually no information on where this came from?

Had anyone here seen this “Apps manager” Pop-Up and does anyone also know how to remove it or where it comes from please?

There seems to me to be no way of findint out how this thing/software/virus or what ever it is, to find how it’s loading into my Windows 7 64-bit professional edition?

Sure can use some help if anyone knows anything about this please?

a screen shot would help us :wink:
