How to Remove Adware from a PC

  • April 28, 2017

If you are constantly seeing popups, advertisements on sites where their shouldn't be, or tech support scams then you are most likely infected with Adware. One of the biggest problems facing computers users is the growing rise of and problems with removing Adware programs. While adware has always been a problem, in the past these programs typically displayed a popup advertisement here and there or displayed advertisements within their own programs, but could be fairly easy to remove.

The current trend, though, is adware that has become more aggressive and displays constant streams of popups, injects advertisements into web sites, and adds their own ads into search result pages. This type of behavior can prevent the proper browsing of the web or using web sites. Even worse, they design the adware to make it extremely difficult to remove or not include any uninstall method at all.

For example, in the images below you can see adware programs that are injecting advertisements so that they overlay the content of web pages or displaying ads for malware. This makes browsing the web more of a chore than a useful and enjoyable activity.

  • Injected Advertisements on Walmart.com
  • Russian Advertisements on FoxNews.com
  • Tech Support Scam Advertisement
  • Fake Flash Player Update Advertisement
  • Advertisements Injected on CNN.com

Another major issues with adware is that some of them also install their own root certificates into Windows so that they can inject advertisements into secure SSL (https://) sites. What's worse is that by using their own root certificates, it also allows adware programs to view anything that is sent to a remote site. This includes passwords, banking credentials, credit card details, or anything else that you may think is secure because you are using a SSL connection.

You can see an example of this type of issue in the image below where an adware program uses their own root certificate to sign the certificate being used by the IRS.gov site. This essentially means that they can listen in on anything you submit to the IRS site.

Bad Cert

As you can see, the main goal of Adware has become to display advertisements in any way possible. Even if this means that they break the security of the computer. For this reasons, it must be a priority that users keep an updated security program installed on their computer, perform routine scans, and remove any adware that is found.

What are the Most Common Symptoms of Adware?

While not all adware programs are the same, for the most part they exhibit the same behavior. Below is a list of symptoms that users may encounter when infected with an adware program:

  • Your browser opens on its own and displays advertisements for adult sites, adult web games, tech support scams, unwanted browser extensions, fake java updates, and fake flash player updates.

  • Advertisements will be injected into web sites that you are viewing. These advertisements may overlay the existing content so you can't read the web page, or replace existing advertisements. Some adware programs also inject Russian advertisements, even for those who are browsing sites that are clearly in another language. These advertisements may not be labeled or could be labeled with words like powered by, ads by, ad by, ads from, etc.

  • When browsing online merchants such as Amazon, Best Buy, Target, Ebay, etc, adware will display advertisements that show deals or pricing comparisons at other sites.

  • SSL certificates for banks or well known sites will show that the certificate was issued by a strange company, like in the image above.

How is Adware installed on a Computer?

Adware is commonly installed by free programs that you download from the Internet. These free programs are either programs that were designed solely as a vehicle to distribute adware or by developers who want to earn revenue from their software. When someone downloads and installs these free programs, adware and other unwanted programs will be installed as well. Therefore, it is important that you pay close attention to license agreements and installation screens when installing anything off of the Internet.

Below you can see an installer that was created to install the legitimate Flash Player, but only after installing a lot of unwanted software on the computer.

Installer

That is why it is important to pay close attention to what installers are doing when you install something from the Internet. Also, if an installation screen offers you Custom or Advanced installation options, it is a good idea to select these as they will typically disclose what other 3rd party software will also be installed. Furthermore, If the license agreement or installation screens state that they are going to install a toolbar or other unwanted adware, it is advised that you immediately cancel the install and not use the free software.

Below I have written a guide that pretty much throws the kitchen sink at your computer. I did this there is not one particular software that can remove every bad program out there. By utilizing a myriad of free programs, you will have enough coverage to remove almost everything that may be bad on the computer. Furthermore, these steps will have you reset your browsers back to their default settings in order to remove extensions, addons, toolbars, and other unwanted browser programs.

Self Help Guide

This guide contains advanced information, but has been written in such a way so that anyone can follow it. Please ensure your data is backed up before proceeding.

If you are uncomfortable making changes to your computer or following these steps, do not worry! Instead you can get free one-on-one help by asking in the forums.

To remove Adware, follow these steps:

1

This removal guide may appear overwhelming due to the amount of the steps and numerous programs that will be used. It was only written this way to provide clear, detailed, and easy to understand instructions that anyone can use to remove this infection for free. Before using this guide, we suggest that you read it once and download all necessary tools to your desktop. After doing so, please print this page as you may need to close your browser window or reboot your computer.

2

To terminate any programs that may interfere with the removal process we must first download the Rkill program. Rkill will search your computer for active malware infections and attempt to terminate them so that they wont interfere with the removal process. To do this, please download RKill to your desktop from the following link.

When at the download page, click on the Download Now button labeled iExplore.exe. When you are prompted where to save it, please save it on your desktop.

Once it is downloaded, double-click on the iExplore.exe icon in order to automatically attempt to stop any processes associated with Adware and other malware. Please be patient while the program looks for various malware programs and ends them. When it has finished, the black window will automatically close and a log file will open. Please review the log file and then close so you can continue with the next step. If you have problems running RKill, you can download the other renamed versions of RKill from the rkill download page. All of the files are renamed copies of RKill, which you can try instead. Please note that the download page will open in a new browser window or tab.

Do not reboot your computer after running RKill as the malware programs will start again.
