Starting today I have ad's popping up everywhere!  There is a program that I can't get stopped called coz32host.exe*32.  Why doesn't Webroot stop it?

Hello and Welcome to the Webroot Community!
It's what we call a PUA please see here on how to remove:

Wow this is some persistent serious process that I can't deal with.  I can't find the source on my box, end the process or deal with it in anyway.  Seems relatively benign, but I don't know what it's doing.  It clones itself somehow trying to adapt to anything I throw at it.  Windows maleware detection doesn't see it either.

Hello kidscasco, welcome to the Community!
I think the best thing to throw at it at this point is a Trouble Ticket to have Webroot Support take a look.  This is a free service with your valid WSA license 🙂
Thanks!  I managed to finally kill the service and find it on my drive.  This bugger was unusually persistant and it is a zoomify (if you do a search you'll see what I mean).  It was disguised as a splash screen recommending a flash upgrade notification for chrome. Since I have had flash crash on a few times lately I figured I do it.  It looked like typical maleware at first but I could not end the processes related to the zoomify: coshost, coszhost32, coshost64.  NOthing would come up when I searched my drives looking for these recent stuff until I allowed all op sys files to be viewed and was then able to find them in C:programdatazoomify2.  At that point I got into the service app editor and manged to stop two cozhost services to allow me to delete the library and executable files in zoomify2.  I think I'm clean now.
I think I misspelled the actual process names in my former:
As I said, they clone (my word there-duplicate themselves under another name and reappear as another similarly named process).  The names from my recollection are cozhost, cozhost32, cozhost64...and there may be more too.

Awesome job if that got rid of it for good!  If it does come back, and you need a hand, just remember Webroot Support is a link away.
Of course we are too if you ever have a question or problem we can help with here on the Community, just let us know!
