My browsers have all been hijacked. Explorer won't open all the way. The tools are grayed out except File and Safety. Safety allows me to go to inPrivate browsing where the browser will work. There tools will allow me to select Manage add-ons. Every add-on I select has the enable and disable buttons grayed out.
I was able to get into the plugins for Firefox and the "Chrome updater" extension was to blame once that extension was shut down so were the adds.
This killed some of Chrome's files. I re installed it and it was a plug in there as well.
Still no explorer though.
