Remove eFast (Removal Instructions)

removal by Lucia Danes - -   Also known as eFast Browser | Type: Adware

eFast software belongs to an infamous spyware category. Although its developers (Clara-Labs) are convincing people that it is “A web browser built for speed, simplicity, and security,” don’t fall into believing this. Instead of accommodating your web browsing, eFast may replace your default web browser without asking your permission and initiate various interferences during your browsing.

Why shouldn’t I trust eFast web browser?

Security vendors claim that eFast hijack can replace or even delete legitimate web browsers on your computer and set eFast app as your default Internet browser. Please be very attentive if you have noticed an increased amount of ads on your screen – if you are using Google Chrome, check the ‘About’ section in Chrome browser’s settings. We have investigated this rogue app and found out that it often pretends to trick computer users and particularly replace Google Chrome browser. After that, it abolishes all shortcuts to other web browsers automatically and prevents users from opening them.

Questions about eFast

This browser threat can infect your computer system unnoticeably. Security experts warn that eFast can be spread bundled with browser hijackers, so don’t be surprised seeing some,, or any other bogus search engine set as your default start page/search provider. As we have already mentioned, this fraudulent web browser can deliver excessive amounts of ads to you, so, as a result, it is considered to be an ‘adware’ program. It has been noticed that it displays commercial and non-commercial advertisements pretending that they are displayed by the websites that the user is viewing. However, if they are marked with text like “Ads by eFast,” “eFast Browser Ads,” “powered by eFast” or similarly, there are no doubts that they are brought by this dubious web browser.

Unfortunately, this eFast software is involved in doubtful third-party advertising campaigns, so we recommend avoiding to click on eFast ads as they can end you up on rogue web sources that might run suspicious businesses, such as the distribution of potentially unwanted programs. That’s why eFast redirects may appear to be risky to you and your PC’s security. Besides, this adware is known to be tracking victim’s browsing activities as well, which is why it may also cause leakage of personally non-identifiable information. To prevent all inconveniences and minimize the risk of another computer infection, we recommend you to install Reimage spyware removal tool and terminate eFast web browser ASAP.

How can I avoid eFast hijack?

Regarding eFast distribution, it would be too nice to say that it is unfair. In fact, this program is distributed using “bundling,” which means that its developers exploit users inattentiveness by spreading this ad-supported web browser with other free programs. To be more specific, this application can be found attached to various freeware as an ‘optional download.’ The sad truth is that people are used to installing freeware by clicking the ‘Next’ button all the time, so the eFast’s developers’ attempts to inject eFast virus along with some download managers and media players can be very successful. To avoid installing eFast and similar PUPs, you have to select “Advanced” or “Custom” settings whenever you install new programs to your PC. Then, you must deselect additional software components by removing the tick mark next to suggestions to install them. DO NOT opt for ‘Default’ or ‘Basic’ one! These settings conceal the information about additional attachments. If you have installed freeware using these options and now eFast virus has occupied your PC, please continue reading on page 2 to find out how to remove it.

Can I remove eFast by myself?

Any legitimate application can be removed manually. However, what regards eFast virus, manual removal is not recommended. As we have already mentioned, this web browser is usually spread by ‘bundling’ and may carry other PUPs alongside. As a result, your computer might have been hijacked by several PUPs at once. Therefore, to fix your computer completely, a full system check with a trustworthy anti-spyware is a number one solution. A reputable spyware removal tool can detect and eliminate all of them.
