I suspect one of my family has recently installed something on our shared desktop without bothering to look at the various 'options' during the install.
As a result, I'm now seeing a 'CoaupExteNsion' extension being added to Chrome. I can delete it through Chrome, but it magically reappears after each reboot.
I see nothing unusual being initiated via msconfig, and can find no reference via Google. MalwareBytes picks up nothing.
Anyone come across this before?
