One of the types malware is an adware virus - a program that runs automatically when you start your computer and system (often this can happen after a while or at a certain frequency). This, of course, distracts users, and often even confuses their thoughts, blocks browser programs and causes harm of a different nature. Many people face this problem, which is why it would be advisable to consider several ways to solve it alternatively. What to do in cases when the browser opens on its own with a website or advertisement, how to remove intrusive and unnecessary content?
The essence of the problem
So, we have a problem: when the system starts, a browser window suddenly pops up and displays unwanted information: advertising, conspicuous banners and announcements of various kinds (it all depends on the purpose of the advertising virus that got onto the computer). At first glance, the influence of the malicious program is harmless. However, all the possibilities of the virus may not end there: problems with connection, transition to home page and the necessary sites are also influenced by viruses of this type.
Why does the browser automatically open when you start your computer: possible reasons
The problem with pop-up ads can be caused by one accidental click. An unverified redirect can cost the user a lot of wasted time removing unwanted adware and restoring the correct functionality of the browser.
Downloading unverified archives and unpacking them directly on your computer is also a dangerous procedure. The contents of the archive may contain the same virus that will have to be fought long and hard.
We should also not believe the advertising banners that we encounter everywhere. Clicking on the link indicated in the beautiful animated picture may cause your computer to become infected. The trick to this method of transmitting the virus is to deceive curious and inexperienced users.
- following unverified links;
- downloading unverified software, files and documents;
- use of unreliable Internet resources;
- Installation and use of dubious programs;
- Late activation (or complete absence) of an antivirus program.
All of the above points apply to possible reasons infecting your personal computer advertising virus, as a result of receiving it from the Internet or through portable media.
What to do when the browser opens by itself with an advertisement or website
Scan your PC with antivirus
The first and alternative method of solving the problem with ad viruses is high-quality prevention. Namely, constant anti-virus scanning of every new file that appears on the computer. The method is effective because viruses of this type cannot enter a computer without the intervention of its owner. Any of his manipulations will still lead to the threat of getting a harmful program, but timely prevention will definitely bear fruit if computer security is really important to you!
Cleaning the system of debris
It is necessary to clean the system of garbage and unnecessary files using utilities designed for this. (For example, AVZ. You can download it from this link: http://blog.fc-service.ru). Before doing this, the system should be started in safe mode.
In the program menu, you must select “Troubleshooting Wizard.” Then « All problems » in point « Danger level » . After the problems found are corrected, it would be a good idea to check the computer with an anti-virus utility, then start the system in normal mode. The advantage of this method is that various utilities are connected to solving the problem, the functionality of which is high, and accordingly, their usefulness will be immediately visible. There is a high probability that malicious adware will be removed from your computer without any consequences.
Disable pop-ups
This method involves disabling pop-ups in your browser. Let's look at the browser menu as an example. Google Chrome. On the menu « Settings » choose « Additional settings » . Next, in « Content settings » go to “Personal information” ». Select “Block pop-ups on all sites.” This way the user will protect himself from pop-up ads and banners. A similar algorithm is also suitable for working with other browsers: the ability to block pop-up windows is available in many browser programs.
Autoloads are not needed for cleaning purposes special programs and funds. This can be done using operating system tools. On the command line (call command line occurs when you press the WIN+R keys) enter the MSCONFIG command. So, we will launch the system configuration. Go to the “Startup” item. In the list of programs that appears, you can see programs that relate to quick start fragmentators, players, etc. But understanding them is not so easy, but intuitively disabling any program from this list will not entail significant consequences.
If you have these installed on your PC OS, like Windows 8 and onwards, the job of cleaning startup is simplified. The developers have moved the “Startup” item separately to the Task Manager. The task manager opens with the key combination Ctrl+Alt+Delete. The Task Manager field shows which processes are running right now, the names and states of programs, along with their impact on CPU performance and hard drive. Here you can disable autoloading.
It would be convenient for advanced users to clean startup through the registry. But this method involves some risk when working with the registry. Accidentally deleting an important entry will lead to a system crash and will make it impossible to start in the future.
The step-by-step sequence of actions when cleaning through the registry looks like this:
- open the registry editor;
- open the registry tree and go to the link HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion;
- pay attention to two sections: “Run Once” and “Run” (the first subparagraph indicates programs that should be run only once, and the second - programs for autorun);
- carefully track the launch paths, names and keys that are available inside some programs;
- remove unnecessary programs;
- the same thing should be repeated with the HKEY_CURRENT_USER registry branch;
It is also worth paying attention to the fact that when you disable any program in startup (in search of a malicious adware virus), it is quite possible to disable the antivirus. This will put the system at even greater risk.
For most cases of blocking pop-up ads, a browser extension called Adguard is suitable. The principle of its operation is this: the add-on itself detects the malicious advertising code and does not allow it to be displayed. You can download the program from the following link: .
Browser pop-up problem advertising banners has quite a large number of solutions. You don't need any special knowledge to eliminate the threat of adware and other malware yourself. The main thing is to follow all the rules for necessary PC protection.
There may be several reasons for the situation when the browser opens on its own with advertising:
- You have installed a web browser extension that displays unwanted advertisements.
- You visit gaming or entertainment sites that are unsafe. From such a site you can get installation of harmful software.
- An advertising virus has been downloaded to your computer – adware/
Dealing with the problem is not that difficult.
Task Scheduler
This is a service in Windows 10 that allows you to delete unnecessary tasks. Are you tired of ads automatically opening in your browser in a new tab, and you're wondering how to remove them? Let's take it step by step:
We told you what to do if pages with advertisements open in your browser. There is another way to get rid of this trouble.
Removing software
What should I do if, when I start my computer, a browser with advertisements opens on its own? Need to remove unnecessary software.
AdwCleaner program
This software is designed to combat ad viruses. It doesn’t see everything else, so it’s not a replacement for a full-fledged antivirus. Download it from the link (adwcleaner.ru) and install it.
It is good because it cleans the registry, carefully removing all traces of adware. 
Click the Scan button and everything will be done.
Browser shortcuts
Sometimes a virus attributes itself directly to the launch of a program. Check it out. Find the shortcut on your desktop. For example, Chrome. Right-click on it and select "Properties". 
Check that nothing else is specified after the startup file. 
If you find something other than quotation marks, delete it. Tabs or windows with advertisements will no longer open.
Protection in Yandex browser
If you use this software, then you can take advantage of the special Adguard function. Click on the menu and select add-ons. 
In the “Security” section, check that Adguard is activated. 
After this, unwanted messages will be blocked automatically and will no longer be opened.
Many of those reading the article have encountered a magical effect when the browser opens by itself, and immediately loads some unknown page with intrusive advertising.
There are many reasons that cause this behavior, but their meaning is the same.
We will look at the most common cases and methods for solving problems for each of them.
Why?
This is the main question that arises for the user when his browser spontaneously opens and displays advertising or is launched by the user and also displays.
The reason for this is the installation of applications downloaded from untrusted sources or the use of various types of downloaders - programs that allow you to download the files you need (app installers, games).
Such unwanted software also includes “gray” software, such as uBar.
Why is this being done? Not good good people This is how they make money.
A couple of hundred lucky people like you will gather in a day and make money for someone together.
An Internet browser can either launch spontaneously without user intervention or display unnecessary pages or the same advertisement (sometimes they change cyclically) after the user opens the browser.
Solution
Since it so happens that the browser opens on its own and shows ads, then you need to find what makes it perform these actions.
In the first case, we will do without third-party tools, since the program was installed without anyone’s knowledge and added to .
First we will delete it, and then the culprit of this task.
- Open the command interpreter through the Start menu or with the key combination Win + R.
- Enter the command in the “Run” text line « msc" and launch it with the "OK" button or the Enter key.
- Click on the button, which will display the contents of the Scheduler.
Here we need to find the task or tasks responsible for launching the web browser. As a rule, they have the names of system services, processes or popular applications, for example, etc. Another distinguishing feature similar recordings - they are performed periodically with a high frequency (once every few minutes, at least several times per hour).
The easiest way to find malicious entries is if there are few of them, using the following algorithm.
- Click on assignment.
- Go to the "Triggers" tab.
- In the form located under the tab name, studying the frequency of task execution.
It is given in the column "Details" usually after brief information about the main launch conditions.
The job status will be "Allowed", and after the path to your Internet browser, the path to the site is written, which is loaded after it is launched.
- Select this Scheduler entry, if you are sure that it is the cause of the browser launch, and delete it through the context menu or with the corresponding button in the toolbar, which is located on the right side of the window.
If the steps performed above did not solve the problem or if a record of this kind was not found, then we are looking for the wrong thing. We view the contents of the “Action” tab for each line.
We are interested in something like executing a batch file with the extension bat or , which contains the path to your Internet browser with a link to a malicious resource or just the address of an advertising site.
The last command causes the page to open in the system's default website browser.
- We delete this entry or, as before, first disable it, and if everything works out, delete it.
After successfully solving the problem, it is necessary to add this task if it did not appear as a result of the work of an installer downloaded from a source with a dubious reputation.
Reset Browser
Such plugins should be removed, which is not always easy.
- From the main menu call the “Extensions” item, located in Additional Tools.
- Finding plugins that you didn’t install yourself, and delete them.
If this does not help or no such ones are found, reset the Internet browser settings ().
- Open "Settings" applications.
- Click “Advanced” at the bottom of the page.
- Scroll down and select “Reset” and confirm the action
Removing traces
Let's assume that an application running in background, or a miniature script in bat format, or vbs, and not a “harmful” installer.
This means you need to get rid of this software.
- Let's launch Task Manager or its alternative, for example, the more functional Process Explorer.
- We find a suspicious process, if one is found, through "Properties" we find the location of the file and complete the task.
How to fix the problem when the site opens when turned on?
It can open either when you turn it on, or when you turn on the computer and load Windows.
An unknown site can open for several reasons, but the most common are:
1) Check the Home page.
How to do this is written in the article.
Go to the settings and make sure that there is no “left” site on the home page.
2) Check browser extensions.
More details about extensions are written in the article.
They are located in different places for each browser. But there is one thing in common - they are in the settings.
For example, in my Iron browser (analogous to Google Chrome), you can simply enter chrome://extensions in the address bar and go to the page with plugins (extensions):
Here you need to pay attention to unfamiliar extensions and disable (or delete them) if they exist.
You can also use the program. Which scans browsers and shows malicious or bad reputation extensions. All you have to do is turn them off yourself.
4) Check the properties of the browser shortcut.
Right-click on your browser shortcut and select “Properties”
and on the “Shortcut” tab pay attention to the “Object” line:
This example shows a line from a well-known Google browser Chrome.
The starting path differs depending on the browser (Opera, Internet Explorer, Mozilla firefox, etc.) and installation paths, but the most important thing is to look at what’s there at the end:
browser.exe
iexplore.exe
chrome.exe
Etc.
Very often, at the end of this path, these same unknown sites are added. Therefore, look carefully at how this line ends.
The main thing is not to have something like this:
If this is the case, then you need to delete this line and apply the changes.
If the shortcut does not allow you to save, then you need to click on the “File location” button in the same window and you will be taken to the folder with the program (browser).
You can remove the old shortcut from the Desktop by first closing the properties window.
Next, in the folder with the program, you need to right-click on the application:
And in context menu select "Send" and there is already the item "Desktop (create shortcut)".
All. Now the new ad-free shortcut is ready.
You can also use free program FixerBro () which checks and restores browser shortcuts automatically. You just need to run it, click the Check button, and then highlight and click Fix.
5) Check the Hosts file.
I highly recommend reading the article. It describes it in great detail and from there you can understand where and what to look for, and most importantly, what the original Hosts file should look like.
If we find something unnecessary, we delete it.
6) Check startup.
Read more about autoloading in the article.
What you should pay attention to? To programs and applications unknown to you. This is more suitable for those cases when when you boot your computer (laptop, netbook, all-in-one PC, etc.), a browser with an unknown site immediately opens.
7) Check installed programs.
On a note:
For more experienced users, it may help that if you open processes, you can see something suspicious and unknown.
Try killing the process or tracking its location and deleting it.
8) Check your computer for viruses.
If manually deleting an advertising site when opening the browser did not work or it did, then you still need to check for viruses.
This can be done using any antivirus, for example those described in the article, or those specially designed for this.
For example, using Hitman Pro () or Malwarebytes Antimalware ().
Download the trial free version, scan and delete.
If, after checking, the browser began to write “An error occurred while connecting to the proxy server” and the pages stopped opening, then do the following:
1 - Start -> Control Panel and there we look for the “Internet Options” or “Browser Options” icon (provided that the view is set to Icons).
2 - In properties, go to the "Connections" tab and click the "Network Settings" button.
3 - Uncheck the Proxy server field and save
You can also use the AdwCleaner program, which is described in the article.
Other solutions and tips on the topic “when you turn on the browser, the site opens”:
If the browser shortcut is not removed, try deleting it in .
If the site began to load after you downloaded something from the Internet, then delete that file or folder.
Look at the folder
C:\USERS\Users\AppData\Roaming\Browsers
If it is there and something is there, then feel free to delete it.
You can look, namely the thread
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
If you see anything suspicious, delete it.
In processes, in extensions, in installed programs Oh, pay attention to the words Search or Update in the titles and their combination. Often "nasties" are disguised using them
Often, either resetting the browser settings or completely and correctly reinstalling it helps.
Check the folder
C:\Users\ (Username)\AppData\Local\(browser)
Paying attention to files and folders with the date they were created. if you remember after which advertisements started popping up, this started, then it would be reasonable to delete this folder/file
We check not only your favorite browser, but everything. It’s not a fact that only he was infected (especially if there are several installed on the system).
For example, a shortcut from Opera may contain a path to a file with a url extension, which means that the default browser (your main one) will open with an advertising page.
That's all. If you have your own ways to fix the problem of opening a third-party site when starting the browser, then write in the comments. I think many will be grateful to you.
Good afternoon everyone.
I think even owners of newfangled antiviruses are simply faced with a huge amount of advertising on the Internet. Moreover, the shame is not even that advertising is shown on third-party resources, but that some software developers build various toolbars into their programs (browser add-ons that are quietly installed for the user).
As a result, the user, despite the antivirus, begins to see intrusive advertising on all sites (or most): teasers, banners, etc. ( sometimes not very impartial content). Moreover, very often the browser itself opens with advertising appearing when you start the computer ( This is generally a transition beyond all “imaginable boundaries”)!
In this article we will talk about how to remove such appearing advertisements, a kind of article - a mini-instruction.
1. Complete removal browser (and add-ons)
2) Remove the browser from the control panel (uninstall programs:). By the way, do not uninstall Internet Explorer!
3) We also remove suspicious programs from the list of installed programs ( control panel/uninstall programs). Suspicious ones include: webalta, toolbar, webprotection, etc. everything that you have not installed and is small in size (usually up to 5 MB usually).
4) Next, you need to go to Explorer and turn on the display in the settings hidden files and folders (by the way, you can use a file commander, for example Total Commander- she sees it the same way hidden folders and files).
Windows 8: Enable display of hidden files and folders. You need to click the “VIEW” menu, then check the “HIDDEN ELEMENTS” checkbox.
5) Check the folders on the system drive (usually drive “C”):
- ProgramData
- Program Files (x86)
- Program Files
- Users\Alex\AppData\Roaming\
- Users\Alex\AppData\Local
In these folders you need to find folders with the same name of your browser (for example: Firefox, Mozilla Firefox, Opera, etc.). We delete these folders.
Thus, in 5 steps we completely removed the infected program from the computer. Reboot the PC and move on to the second step.
2. Scan the system for mailware
Now, before reinstalling the browser, you need to completely check your computer for the presence of adware (mailware, etc. garbage). I'll give two best utilities for such work.
2.1. ADW Clean
An excellent program for cleaning your computer from all kinds of Trojans and adware. No lengthy setup required - just download and run. By the way, after scanning and removing any “garbage”, the program restarts the PC!
2.2. Malwarebytes
This is probably one of the best programs with a huge database of various adware. Finds all the most common types of advertising embedded in browsers.
Need to check system disk C, the rest is at your discretion. The scan needs to be complete. See screenshot below.
Scan your computer using Mailwarebytes.
3. Installing a browser and ad blocking add-ons
By the way, it wouldn’t be superfluous at all - special. program for blocking intrusive advertising. Works with absolutely all browsers!
Actually, that's all. By following the instructions above, you will completely clear your computer of adware and advertisements will no longer appear in your browser when you start your computer.
All the best!
