I have been getting popup ads that redirect to rover.ebay. http://blog.helpvirusremoval.com/rover-ebay-com-how-to-remove-delete-removal
There seem to be quite a few websites with malware removal instructions which appear to be run by Enigma Software, the publisher of SpyHunter.
use adwcleaner https://www.wilderssecurity.com/threads/adwcleaner-updates-and-discussion-thread.345634/ rover.ebay is essential for ebay business and buyers, but as single popup its adware on your system. enigma has an aggressive marketing - such sites help experienced users but not the common people. better is to ask before wasting money!
