@edgarblythe,
Since you are using Chrome instead of IE anyway, you might try just resetting IE to see if it cleans out any extensions:
a. Press Windows logo + R to open the Run dialog box.
b. Type inetcpl.cpl in the run dialog box, press Enter.
c. Now click the advanced tab and then click Reset.
d. Click apply and then ok.
This still doesn't sound like Malware to me because it keep taking you to a Microsoft site. It seems more like some type of Microsoft "feature" run amok.
