What Is Hptop.ru?
Your default browser may open new tabs periodically and direct you first to http://hptop.ru/magic (or http://hptop.ru/magics, http://hptop.ru/magicm, http://hptop.ru/magicsm) URL, then redirect to http://b2.ijquery11.com/…, and finish with some site with ads or the one convincing you to download suspicious software. That happens because of adware that got installed on your computer. Most likely the adware ended up there when you downloaded something from a fishy website and got a bunch of malware and PUPs (potentially unwanted programs) instead. You may follow the instructions below to get rid of http://hptop.ru/magic/ pop-ups.
