Quick Site

Quick Site is a browser hijacking component that can alter the settings of Chrome, Edge, and Firefox (and other browsers) without a notice. Quick Site’s major goal is to transform the targeted browser into an ad-display platform for promoting certain websites, software, different products and services.

Quick Site
A common way for the creators of the Quick Site virus to make money is via the use of Pay-Per-Click or Pay-Per-View payment methods.

A “browser hijacker” may often be mistaken for malicious software, but in reality this is software that is considered to be a “PUP” (potentially unwanted program) that should best be removed. Despite the fact that many people perceive this program to be malware when they encounter it for the first time, a browser hijacker differs substantially from actual malware, such as Trojan Horses, Spyware, Viruses, Rootkits, and Ransomware, in terms of their function and goal.

Ads, banners, pop-ups, and other types of advertising are often used by Browser Hijackers like Quick Site or Viewer Extension to entice you to click on a link and see a product or service. A common way for the creators of these applications to make money is via the use of Pay-Per-Click or Pay-Per-View payment methods.

Most hijackers aren’t designed to do harm to the systems they’re placed on. For the sake of advertising, however, apps like Quick Site tend to make changes to things like the system’s registry, and Startup settings, as well as the default browser’s settings. Some of the most visible changes include a new search engine and a homepage that cannot be uninstalled. Often, these changes are done without the user’s awareness or agreement, and as a consequence, they are referred to be potentially unwanted.

Why should you be concerned?

For the most part, a program like Quick Site does not represent a serious threat to the computer’s system, or your personal information. On the other hand, a browser hijacker like this one may create a variety of issues that should not be neglected.

As a starting point, you’ll have to deal with annoying pop-up advertisements and a browser that has undergone major alterations. And while, to some, this may not seem like a big deal, of more concern is the third-party advertising content shown in your browser.

It’s quite possible that some of the advertisements generated by Quick Site may lead you to rogue websites that may have phishing components since no one has control over what is advertised. And if you land on such a site, you may be prompted to download malware in the form of free programs or share your personal information with scammers.

The third main concern is the changes to the operating system and the browser. Even if the changes a browser hijacker like Quick Site may impose aren’t directly harmful to the computer system, Trojans, Ransomware, Viruses and Spyware, may still abuse them to enter a computer.

Because of this, removing Quick Site and all related files and settings from your computer is the only reasonable course of action. Anti-malware software and a full guide on how to remove Quick Site and uninstall its components are given below.

Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

    After you open their folder, end the processes that are infected, then delete their folders. 

    Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections. 


    Hold together the Start Key and R. Type appwiz.cpl –> OK.


    You are now in the Control Panel. Look for suspicious entries. Uninstall it/them.

    Type msconfig in the search field and hit enter. A window will pop-up:


    Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.


    Hold the Start Key and R –  copy + paste the following and click OK:

    notepad %windir%/system32/Drivers/etc/hosts

    A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

    hosts_opt (1)

    If there are suspicious IPs below “Localhost” – write to us in the comments.

    Open the start menu and search for Network Connections (On Windows 10 you just write it after clicking the Windows button), press enter.

    1. Right-click on the Network Adapter you are using —> Properties —> Internet Protocol Version 4 (ICP/IP), click  Properties.
    2. The DNS line should be set to Obtain DNS server automatically. If it is not, set it yourself.
    3. Click on Advanced —> the DNS tab. Remove everything here (if there is something) —> OK.

    • After you complete this step, the threat will be gone from your browsers. Finish the next step as well or it may reappear on a system reboot.

    Right click on the browser’s shortcut —> Properties.

    NOTE: We are showing Google Chrome, but you can do this for Firefox and IE (or Edge).


    Properties —–> Shortcut. In Target, remove everything after .exe.
