If the reader regularly visits web resources of dubious content or downloads any utilities from there, he can be sure that sooner or later the PC will become infected with viruses. One day, the user will find that when you turn on the computer, a browser opens. A page with advertising and obscure links will appear in the browser window. If the PC owner has encountered a similar problem, this means that the system is infected with malware. To prevent outsiders from gaining access to sensitive data, the user needs to delete the virus code.
Performing startup cleanup
The first step is to check the parameters. The list of startup programs may contain a browser. If so, then the application will start with the computer.
To clean the Startup section, open the Start menu. Then, type “msconfig” in the search bar. A new window will open. The user should switch to the "Startup" tab, uncheck the unknown applications and save the changes.
These actions will not be enough. If a malicious program is running on the computer, then after rebooting the PC, the advertising tabs will appear again. Do not worry. The user should proceed to the next step.
Manual registry cleaning
First you need to restart your computer. As soon as the browser starts, the user needs to remember the name of the site that opens first. It is indicated in the address bar. If the owner of the computer does not have time to complete this action, then it will be transferred to another site. Then the user will have to restart the PC again and repeat the procedure.
To get rid of this problem, you can simply disconnect the device from the Internet. In this case, the browser will start again, but redirection will not occur. The user will see the site that he needs. It is necessary to hold down the keys “Win + R” on the keyboard. A new window will appear.
In it, specify the command "regedit" and click on the "OK" button. In the registry editor you need to select the folder "HKEY_USERS", hold down the keys "Ctrl + F" and enter the name of the site. Files found by the utility are deleted using the context menu, which can be called up by right-clicking the optical mouse. In order not to make a mistake, the user should focus on the item “Value” in the table. If the address contains the site name, you can safely click on the "Delete" button.
Automatic registry cleaning
The search for redundant entries must be repeated until the desired phrase ceases to appear in the results. To speed up the procedure, you should use a special program that performs analysis and cleaning of the registry in automatic mode. The most popular utilities are CCleaner or AdwCleaner. The program interface is simple and straightforward, so there should not be any difficulties.
What should a user do if a browser with a website opens when the computer is turned on? First you need to download, install and run the utility to clean the system. Then you need to open the "Registry" section and start scanning by clicking on the "Search for problems" button.
After completing the procedure, click on the “Fix selected” link. Next, you need to restart the computer. If the ad browser starts up again, the user will have to consider other options for removing the malicious application.
Antivirus scan
On the PC, infected files can be found that automatically restore deleted registry entries. To get rid of turning on the browser when you turn on the computer, you must run a system scan with an antivirus program. To do this, open the utility window and click on the “Start Scan” button. Then you need to wait until the end of the procedure.
The program displays a list of advertising files. You need to select the objects and click on the “Delete” button. After that, you need to confirm the action by clicking on the "Continue" link. The procedure will be completed.
After the computer restarts, you can run a rescan. Testing will last longer, but will show better results. If the program detects other advertising files, the deletion procedure must be repeated.
Checking the browser shortcut
Often, a malicious utility saves records about itself in the browser settings. Therefore, the user hears strange signals when the computer is turned on. All unnecessary entries can be deleted manually. In this case, you do not have to fear that the user will somehow harm the system. First you need to check the browser shortcut.
Advertising sites are usually registered in the properties. To perform the procedure, you need to right-click the optical mouse on the browser shortcut. Then select the line “Properties”. Next, you need to switch to the "Shortcut" tab. The user needs to focus on the "Object" column.
Additional information after the line "Application \ chrome.exe" can be safely deleted. Then you need to go to the "Shared folder" tab. There should be no other values after the line “application”. To get the best result, you can launch the control panel, select the "Internet Options" section and go to the "General" tab. Then you need to remove the address of the advertising site in the "Home" field and save all the changes.
Check your browser settings
After the user performs the above actions, the advertising windows should disappear. If the Yandex.Browser program opens when you turn on the computer, it means that the data of the malicious application is stored in the browser. Extra information can be deleted manually. To do this, launch the browser and click on the image of 3 lines in the upper panel. The settings will open.
Here you need to select a search engine. If the Google Chrome browser opens when you turn on the computer, then the owner of the PC should click on the 3 dots image in the top panel and go to settings. Then select the “Add” line in the “At Startup” section. Next, you need to delete unknown addresses and check the box "Open a new tab." After that, you need to select a search engine.
Removing ads in other browsers
If the Opera browser opens when the computer is turned on, the user will need to click on the "Menu" button, go to the "General Settings" section and select the "Advanced" line. Then you need to switch to the “Content” tab. Next, click on the “Configure JavaScript” link and delete the unknown addresses. After that, select “cookies” and clear them completely.
Internet Explorer users may also one day notice that a browser opens when you turn on the computer. How to remove data from a malicious application from the browser? To do this, find the "Service" button and select the "Settings" line. The owner of the PC must go to the "Toolbar and Extensions" and disable unknown resources. The same actions must be performed in the "Search Service".
If the Mozilla Firefox browser opens when you turn on the computer, then the user will have to go to "Settings", switch to the "Basic" tab, select the "Start" line and click on the "Show a blank page" link.
System Restore
The above methods work in 99% of cases. If the owner of the PC still sees the browser with ads and hears strange signals when the computer is turned on, he must perform system recovery. To do this, open the Start menu, select the “All Programs” line and go to the “Utilities” folder.
Then you need to click on the link "System Restore". In the new window, select the recovery date and click on the “Next” button. After completing the procedure, turning on the browser when the computer is turned on will be stopped.
