Skip this and learn how to remove AdSentinel!

While running, AdSentinel will use a renamed Privoxy proxy server to inject javascript into the header and footer of web sites that you are viewing. That injections that occur will be determined by the default.action and default.filter configuration files that are bundled with AdSentinel. This allows it to inject scripts that can display advertisements, gather statistical information, change the layout of a page, and perform redirects depending on what javascript is injected. This is a major cause of concern as people who have this program installed may not even know that this is occurring.

## How was AdSentinel installed on my Computer?

It is important to note that the AdSentinel is bundled with and installed by free programs that did not adequately disclose that other software would be installed along with it. Therefore, it is important that you pay close attention to license agreements and installation screens when installing anything off of the Internet. 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.

In my opinion, the AdSentinel adware program is a large privacy risk due to the fact that it can inject any javascript script into web sites that you are visiting. This provides a great deal of control to not only your browsing experience, but also to your privacy. Therefore, I feel if you have AdSentinel installed you should remove it using the following guide for free.

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.

##### Rkill

3

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

4

##### Malwarebytes Anti-Malware
5

6

Double-click on the icon on your desktop named mb3-setup-1878.1878-3.5.1.2522. This will start the installation of MBAM onto your computer.

7

When the installation begins, keep following the prompts in order to continue with the installation process. Do not make any changes to default settings and when the program has finished installing, make sure you leave Launch Malwarebytes Anti-Malware checked. Then click on the Finish button. If MalwareBytes prompts you to reboot, please do not do so.

8

MBAM will now start and you will be at the main screen as shown below.

We now need to enable rootkit scanning to detect the largest amount of malware and unwanted programs that is possible with MalwareBytes. To do this, click on the Settings button on the left side of the screen and you will be brought to the general settings section.

Now click on the Protection tab at the top of the screen. You will now be shown the settings MalwareBytes will use when scanning your computer.

At this screen, please enable the Scan for rootkits setting by clicking on the toggle switch so it turns green.

9

Now that you have enabled rootkit scanning, click on the Scan button to go to the scan screen.

Make sure Threat Scan is selected and then click on the Start Scan button. If there is an update available for Malwarebytes it will automatically download and install it before performing the scan.

10

MBAM will now start scanning your computer for malware. This process can take quite a while, so we suggest you do something else and periodically check on the status of the scan to see when it is finished.

11

When MBAM is finished scanning it will display a screen that displays any malware, adware, or potentially unwanted programs that it has detected. Please note that the items found may be different than what is shown in the image below due to the guide being updated for newer versions of MBAM.

You should now click on the Remove Selected button to remove all the selected items. MBAM will now delete all of the files and registry keys and add them to the programs quarantine. When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so. Once your computer has rebooted, and you are logged in, please continue with the rest of the steps.

12

You can now exit the MBAM program.

13

14

If you selected to continue, you will be presented with the start screen as shown below.

15

Now click on the Scan button in AdwCleaner. The program will now start to search for known adware programs that may be installed on your computer. When it has finished it will display all of the items it has found in Results section of the screen above. Please look through the results and try to determine if the programs that are listed contain ones that you do not want installed. If you find programs that you need to keep, then uncheck the entries associated with them.

For many people, the contents of the Results section may appear confusing. Unless you see a program name that you know should not be removed,please continue with the next step.

16

To remove the adware programs that were detected in the previous step, please click on the Clean button on the AdwCleaner screen. AdwCleaner will now prompt you to save any open files or data as the program will need to close any open programs before it starts to clean.

17

When your computer reboots and you are logged in, AdwCleaner will automatically open a log file that contains the files, registry keys, and programs that were removed from your computer.

18

##### HitmanPro

When you visit the above page, please download the version that corresponds to the bit-type of the Windows version you are using.

19

Once downloaded, double-click on the file named HitmanPro.exe (for 32-bit versions of Windows) or HitmanPro_x64.exe (for 64-bit versions of Windows). When the program starts you will be presented with the start screen as shown below.

Now click on the Next button to continue with the scan process.

20

You will now be at the HitmanPro setup screen. If you would like to install the 30 day trial for HitmanPro, select the Yes, create a copy of HitmanPro so I can regularly scan this computer (recommended) option. Otherwise, if you just want to scan the computer this one time, please select the No, I only want to perform a one-time scan to check this computer option.

Once you have selected one of the options, please click on the Next button.

21

HitmanPro will now begin to scan your computer for infections, adware, and potentially unwanted programs. When it has finished it will display a list of all the items that Hitman has found as shown in the image below. Please note that the items found may be different than what is shown in the image.

You should now click on the Next button to have HitmanPro remove the detected items. When it is done you will be shown a Removal Results screen that shows the status of the various programs that were removed. At this screen you should click on the Next button and then if prompted you should click on the Reboot button. If HitmanPro does not prompt you to reboot, please just click on the Close button.

Once your computer has has restarted or you pressed the Close button, you should now be at your Windows desktop.

22

As many malware and unwanted programs are installed through vulnerabilities found in out-dated and insecure programs, it is strongly suggested that you use Secunia PSI to scan for vulnerable programs on your computer. A tutorial on how to use Secunia PSI to scan for vulnerable programs can be found here:
