What is adware? How to remove adware virus from windows avg antivirus does not remove win32 adware.

If pop-up ads suddenly appear on your computer, or if your browser redirects you to unfamiliar websites, your system may be infected with adware. Windows and macOS are vulnerable to malware that can take over the browser and open ads all the time. If the computer is infected and not protected by antivirus or antispyware, you should worry about the security of the system. Fortunately, there are just as many security experts as there are attackers, and these experts have developed many ways to manually remove malware that has infiltrated the system.

Steps

How to remove adware in Windows

Boot into Safe Mode with Networking. Disconnect all external storage media (such as CDs and flash drives) from the computer, and then restart the computer in safe mode.

• Windows 8 and 10:
  • Press Shift and click on the power icon. The computer will restart again.
  • When the screen displays a list of options, click Troubleshooting > Advanced Options > Boot Options > Restart.
  • On the new screen with boot options, press the key indicated next to the option "Enable safe mode with network drivers loading" (as a rule, you need to press the F5 or 5 key).
• Windows 7 and older: Open the Start menu, click the arrow next to Shut down, and select Restart. When the computer goes to reboot, press the F8 key to open the boot menu. Use the arrow keys to highlight the option "Safe Mode with Networking" and press ↵Enter.

1. Launch your browser to check for malicious extensions or add-ons. Adware is often distributed as extensions or add-ons for web browsers.

   • In Chrome: Open the Chrome menu (click the three horizontal lines icon in the top right corner) and select More Tools. Click "Extensions", find extensions you don't recognize and click "Remove" for each one.
   • Internet Explorer: Click Tools > Add-ons. Click "All Add-ons" to view a list of all installed extensions. Select any unfamiliar extensions and click Disable > Close.
   • Firefox: Open the Firefox menu (click the three horizontal lines icon in the top right corner) and select Add-ons. Now click "Extensions" and look for all unfamiliar extensions. To disable an extension, click on it and then click Disable.

2. Check your browser home page, search engines, and other default settings. Sometimes the adware changes the home/main page and the browser's main search engine.

   • Chrome: Click "Settings" in the Chrome menu, and then click "Set Pages" (under "Launching Chrome"). If you see an unfamiliar web page address in the list that opens, click on the icon in the form of three vertical dots to the right of the address and select "Delete" from the menu.
     • Make sure the Chrome buttons are working properly. Click "Settings" in the Chrome menu and then find the "Appearance" section. Now activate the option "Show Home button" and check the box next to "Quick access page".
     • Check the search engine. Click "Settings" in the Chrome menu. Now, in the Search Engine section, click on Manage Search Engines. Click on the icon in the form of three vertical dots to the right of the desired search engine and select "Set as default" from the menu. Make sure the URL on the right side of the screen matches the name of the search engine; for example, if you see Yahoo.com on the left and an address other than search.yahoo.com on the right, click the three vertical dots icon to the right of that address and select Remove from List from the menu.
   • Internet Explorer: Click Tools > Add-ons. Click on "Search Services" and select the desired search engine (Google, Yandex, and so on). If there is an unfamiliar search engine in the list, click on it, and then click "Delete".
     • Go back to the "Tools" menu, select "Internet Options" and find the "Home Page" section. If this section contains an unknown web page address (which is used as the browser's home page), delete it and click "Blank".
     • Find the Internet Explorer icon on the desktop or in the corresponding folder. Right-click on the icon and select "Properties" from the menu. Go to the "Shortcut" tab and look at the "Object" line. If there is any text after iexplore.exe, delete it (do not touch iexplore.exe) and click OK.
   • Firefox: On the Firefox settings page, go to the "Start" tab and in the "Home Page" section, check the box next to "Search the web."
     • To check your search engine settings, go to the "Search" tab and in the "Default search engine" section, select the desired search engine. If you see an unfamiliar search engine in the One-Click Search section, select it and click Remove.

3. View programs in Startup. Click ⊞Win+S to open the search box. Type msconfig to find the System Configuration utility. When this utility appears in the search results, click on it. If a pop-up window opens, click "Yes" or "OK" in it.

   • Click the Startup tab to view a list of programs that start when the system boots (Windows 8/10 users will be redirected to the Task Manager, but the rest of the steps are the same).
   • Look through the Startup list and look for unknown programs in it. If you don't know what a particular program is for, open a web browser, enter the name of the program in a search engine and read about the program - it can be both useful and malicious. Please note that the name of the developer company is indicated next to the name of the program. The company name can also identify malware. To disable a program in Startup, uncheck the box to the left of the program (in Windows 8/10, click on the program and click "Disable").

4. Save your changes and restart your computer. For Windows 7 and older, click Apply > OK. On Windows 8 and later, simply press "X" to close the Task Manager window.

   Remove unknown programs. If pop-ups still appear on your computer, find and remove unknown programs. Open the search bar, type Programs, and then click Programs and Features in the search results.

   • In the list of installed programs, find programs that you do not know. The list can be sorted by installation date - to do this, click on "Installed" at the top of the list.
   • To uninstall a program, click on it and then click Uninstall. When the program is uninstalled, restart your computer.

5. Download MalwareFox Anti-Malware. If you were unable to find and remove the adware manually, use the MalwareFox program - open its website and click "Free Download" (Download for free). Select "Download Free Version" to start the download process; save the installer to your desktop when prompted.

   • If you are unable to download the program, download it on another computer and then copy it to a flash drive or CD/DVD. Now connect the disk or flash drive to the infected computer, click ⊞Win+E to open the Explorer window, and then double-click the disk/flash drive in the left pane.

6. Launch Anti-Malware and then run a scan. Double click on the downloaded file to launch the program and then click "Scan". When the program detects adware, its interface will turn red; To remove the adware, click Next. If you are unable to remove the malware (which happens very rarely), write down the name of the adware and read on.

   Find Symantec adware removal instructions. In Safe Mode or on another computer, open Symantec's malware list. On the site you will find links to instructions (in English) for removing almost all existing types of adware. The malware list is sorted alphabetically, making it easier for you to find your adware. When you find your adware listed, click on its name.

   Click "Removal" for instructions. The first set of instructions is for users of Symantec software. If you do not use the programs of this company, go to the second step and follow the instructions. Adware are different and some are harder to remove than others. Restart your computer when you have followed all the instructions that apply to your adware.

   Run System Restore. If you are still unable to remove the malware, restore the system to a date when everything was fine with the computer.

   How to remove adware in macOS

   1. Block pop-ups in your web browser. This important step will allow you to complete the rest of this method with minimal inconvenience.

      • Safari: Open the Safari menu and select Preferences. Click "Security" and select "Block pop-ups". Uncheck the "Allow WebGL" and "Allow Plugins" options.
      • Chrome: Open the Chrome menu (click the three horizontal lines icon), click Settings, scroll down and click Advanced. Now click on "Privacy" > "Site Settings" > "Block All Pop-ups".

   2. Look in your browser settings for unfamiliar search engines and extensions.

      • Safari: Open the Safari menu and click Preferences > Extensions. If you see an unfamiliar extension in the list, select it and click Remove. Now go to the General tab and make sure the correct search engine is selected as the main search engine. If not, change the search engine to the one you need. Some Safari options are set by default. We recommend choosing Google as your primary search engine.
      • Chrome: Open the Chrome menu and click More Tools > Extensions. Click "Remove" for each unfamiliar extension. Now from the Chrome menu, select "Settings", scroll down and click on "Advanced".
        • Scroll down to the "Launch Chrome" section and make sure the "New Tab" option is selected.
        • Scroll down to the Search Engine section and click Manage Search Engines. Make sure you are familiar with each search engine that appears in the top window. Pay attention to the URL on the right, as the malware may masquerade as Google but actually have a different website. To remove unfamiliar search engines, select them, open the right menu and click "Remove from list".

   3. Download Apple's Popup Blocker PDF. Do this because the following steps require you to close your browser. Type https://support.apple.com/en-us/HT203987 in the address bar of your browser, and then click File > Print > Save as PDF. Select your desktop as your download folder to quickly find your document.

   4. Use the "Go To Folder" method to find the adware. You will use this method often, so get familiar with it.

      • Open the downloaded PDF, scroll down to the list of files that starts with /System/Library/Frameworks/v.framework . Highlight the first line in this list of files and click Edit > Copy.
      • Open Finder and click View > Columns. Now open the "Go" menu and select "Go to folder" in it.
      • Click Edit > Paste to paste the copied line into the field. Click ⏎ Return to find the file. If the file is found, drag it to the Trash. If not, copy the next line in the PDF document list and repeat the process.
      • Repeat the "Go To Folder" method with each file in the PDF document's list. When you're done, empty the Trash by clicking Finder > Empty Trash. Now restart your computer.

   5. Find out if other known malware is running. If the adware was not removed, open Finder and click Programs > Utilities > System Monitor. On the CPU tab, click Process Name to sort the entries alphabetically. Now look for processes called "InstallMac" or "Genieo".

      • If you find one of the above processes, repeat the "Go To Folder" process with the following line: /private/etc/launchd.conf . When finished, restart your computer.
      • Return to the PDF document and scroll down to the "Remove Genieo, InstallMac" section and repeat the "Go To Folder" method with each file listed under "Restart your Mac" (Restart your Mac). Once you've processed each file and dragged the appropriate files to the Trash, restart your computer.
      • When the computer restarts, apply the Browse to Folder method to the /Library/Frameworks/GenieoExtra.framework file. Then empty the Trash (in Finder).
      • Keep Malwarebytes Anti-Malware on a flash drive or CD/DVD in case of an emergency.

      Warnings

      • Often, adware enters a computer when a message “Attention! The computer is infected! (or similar). Remember that well-known antivirus/antispyware programs do not send messages to the web browser - their warnings are displayed in separate windows with the name of the antivirus/antispyware program or in pop-up notifications on the Windows taskbar.
      • If the above methods are not successful, contact a specialist.

In fact, this is special software that is installed directly on the user's computer and displays advertisements.

There are online and offline adware programs. What does it mean?

Adware advertising from a developer's point of view

To begin with, let's try to figure out why software developers generally embed in their products and how this happens.

Features of online adware

In this case, advertising is constantly pumped up from some external Internet source. According to the principle of operation, such programs are somewhat reminiscent of ordinary ones. Considering that the display of advertising is possible only if there is an Internet connection, this scheme is used, as a rule, precisely on those programs that are focused on working on the network.

Services for introducing adware into regular programs are offered by specialized advertising networks (for example, Soft.Tbn.Ru). Programmers participating in the network receive a special component SoftTBN.dll from the organizers and then integrate it into their programs.

When these programs are launched by users, banners are downloaded from the central database and displayed in the interface. If there is no Internet connection, those banners that were accumulated by the program earlier are displayed.

However, would such an adware program be effective? After all, firstly, the presence of banners in the program almost always annoys users. Secondly, embedding advertising modules increases the number of errors in the program code. In fact, the image of the program suffers, and people begin to look for alternative options, enriching the developers' competitors.

Features of offline adware

In turn, offline-adware programs do not turn to external sources to display ads. The entire set of banners is initially present in the program code and does not change during the entire period of its use. The Internet is accessed only when the user clicks on the ad.

The behavior of offline-adware is completely under the control of developers, which significantly reduces the number of errors during operation. In addition, programmers can control which ads will be displayed in - as a rule, they are of interest to users of the program and do not carry malicious information. It is much more difficult to crack the code of such programs.

The only drawback for developers, perhaps, is the limited set of banners. However, developers compensate for this shortcoming by regularly releasing new versions of the program.

If you encounter an adware virus…

How is the adware? The above information shows that adware is not a separate piece of malware, but a component of other software. That is, most modern antiviruses believe that this is a necessary file for the operation of a regular program.

That is why there are special utilities designed to remove adware. What are these programs? The most popular and effective products at the moment are:

• adware;
• Spybot - Search & Destroy;
• Spyware Terminator;
• a-squared Free.

These programs automatically detect and remove files responsible for advertising. At the same time, the functionality of the program itself does not suffer - you continue to use it, but you do not see annoying banners.

In general, like any other advertising, adware also has its advantages. What does it mean? Typically, ads are targeted - that is, users are shown only those ads that may be of real interest to them. So, before deleting adware files, take a closer look at the ads: maybe you will find exactly what you need?

Adware Helpers are a set of harmful components used for various purposes. Some of them help unwanted/dangerous programs get into your computer undetected, others are used to hide malware in the system. In most cases, Adware Helpers are used to collect sensitive information such as bank details, various usernames and passwords. However, they can also be used to spread malware involved in DoS attacks, bitcoin mining, etc. For example, if you find PerformerSoft LLC or another suspicious program on your computer, it may have been installed using Adware Helpers. Because of all these features, security experts named this program Backdoor.Win32.Rbot. If you think that this virus has entered your computer, do not wait for it to download more serious viruses, scan your system with a reliable antivirus program such as .

How can Adware Helpers get on my computer?

Adware- a program that redirects search queries to sites with advertisements, displays advertisements on your devices and collects information about you (for example, which sites you visit) in order to display advertisements more interesting to you.

Such programs usually do not have an icon in the taskbar and in the program menu. Programs do not show what is in the system, in addition to collecting information and showing ads.

Adware programs are often confused with Trojans. Their main differences are that Trojan spyware takes over information without your knowledge, while Adware starts collecting information after your permission.

Adware can end up on your computer in several ways:

• When opening an infected site(with the help of hacker technologies, an Adware program is installed on your computer without your consent after visiting a malicious site. This happens due to browser vulnerabilities. Such adware programs are known as Browser Hijackers);
• Shared with shareware or freeware(This method of infiltration by Adware is legal and helps developers earn ad revenue).

Some Adware programs use the same methods of penetrating the device and running invisible as viruses and do not have a kill procedure. Unfortunately, anti-virus programs are sometimes unable to determine the degree of danger of a certain adware due to the fact that they may be present on the computer quite legally. To protect yourself from annoying ads on websites, you can use special filters that fight it quite well. Kaspersky anti-virus programs give the user a choice: whether or not to detect Adware and how to respond to them.

1. Do not detect adware programs(Some programs can be added to the list of exceptions and the antivirus will not notice them. In addition, if you are sure that the program caught by the antivirus is allowed by you, then you can turn off the detection of such programs. By doing this, you agree that the software product is not harmful to your computer ).
2. Removing the Adware Program(if an unfamiliar program was installed on your computer without your consent, then this is already a reason to assume that the program is dangerous. In such cases, the antivirus destroys such a utility).

Most free programs stop showing ads after you buy or register them. But if third-party Adware programs are used, they do not disappear from the device after purchase. In addition, it happens that after removing them, the installed software starts to work incorrectly.

The principle of profiting from an Adware application is quite simple. The creators of such programs cooperate with advertising agencies, which in this situation act as a broker, or work directly with advertisers, but this is extremely rare.
