Malwarebytes and Bitdefender do not work on this issue anymore at least with Chrome. The only thing that did was a hard reset. Go to chrome>settings>show advanced settings>Reset settings
That suggests that the adware had been removed, but you hadn't yet reset the home page and search engine settings. That's something that has to be done manually, and that's the only thing that resetting Chrome's settings would have done for you.
Also I install very little software so I KNOW where it came from. My daughter is in college and they gave us a free subscription to MS Office which I downloaded and installed. That very day is when this offers4u crap started showing. That'll teach me to go to the evil empire...
I'm not much of a fan of the "Evil Empire" either, but Microsoft definitely doesn't get into the business of distributing adware. If that installer is actually where the adware came from, then the installer didn't come from Microsoft.
