I am a Windows PC user.  Every time I would go on IHUB, a program called IObit gets installed on my computer.  Yes, I am using protection. But, apparently your basic virus scanners do not pick up on this.  IObit Toolbar is a browser extension which hijacks the browser search and home page of multiple major browsers and is bundled with other potentially unwanted programs.  I did follow your suggestion and yes, I did find those other files as well.  Thank you!!!
