vnpapps ads infected Google Chrome
Google Chrome has been infected with vnpapps ads, does anyone know how to remove these. I don't see an extension and program to uninstall. It appears to only have infected Google Chrome, Safari and Firefox.
There doesn't seem to be much information on this type of Malware.
Thank you for your help.
