EFast Browser is not the right web client to use if you want to achieve optimal operating speed. This application behaves in a manner that the majority of people may find annoying and unenjoyable. The negative feedback is the reason security experts unanimously define eFast Browser as a Potentially Unwanted Program (PUP). What may bother the users is that this questionable web client may display too many commercial materials. These ads are a way for the developers of this software to generate income. The sponsored links may lead you to some partner sites, whose administrators willingly pay referral commissions in exchange for a steady flow of visitors. Some of these partner sites may be unknown e-commerce platforms that seek to grow, but other pages may be created with the sole intention to spread harmful content. When you take in mind that you can never be sure where the particular ad will take you, the best decision is to abstain from clicking on any of the commercial materials. If you use eFast Browser, you may detect numerous intrusive pop-ups, banners, eye-catching animations or videos. If you notice some words with a double green or blue underlining, then they may be hyperlinked. Some ads may be positioned in a clever way to make you click on them even if you don't want to do so. For example, they may overlap some page buttons. Another tactic is to create a fake 'X' button that doesn't close the commercial window but opens the link. As a consequence of the presence of so many marketing elements, the operating speed of this PUP may be lower than the speed of popular browsers such as Google Chrome, Mozilla Firefox and Internet Explorer. The removal of this questionable application may be difficult, so you should do it with an updated anti-malware tool.
