This is the message that appears in Bitdefender
The file C:\Dropbox (Personal)\.dropbox.cache\new_files\18ce42da3f5e1cb63360e79491c230ea is infected with Adware.AdWrapper.D and was moved to quarantine. It is recommended that you run a System Scan to make sure your system is clean.
I've have run many system scans - repeatedly deleted the file and yet it keeps coming back - about once every 20 minutes -
Does anyone know WHERE it originates and how to permanently get rid of it?
DRIVING ME SPARE
thanks!
