How to protect browser from malware

delete malware virus

It is no secret that the most frequently used programs on a computer/laptop are different browsers. Through them, the user has access to the Internet, receives, distributes, and sends information to other users. Therefore, viruses have appeared that only target browsers, without affecting other programs. Antivirus programs often do not detect such viruses; meanwhile, the user gets a lot of advertising because of them, pop-up banners, redirects to other sites, and besides the operating system slows down. These and other problems associated with browser viruses can be fixed by clearing Google Chrome, Safari, Mozilla, Edge, IE and other browsers. Let’s take a look at what a virus is in browsers, how to remove malware safely and effectively.

Is there a virus in the browser, how does the infection occur?

To begin with such an article, it is logical to cite the symptoms of a browser infection with malware (browser hijacker, pop-ups, advertising modules, adware, etc.).

The most common symptoms of a browser infection:

  1. Advertising banners, teasers, a link with a proposal to buy something, sell, etc. Moreover, such advertising can appear even on those sites on which it has never happened before.
  2. The appearance of various windows with a warning that in a few days you will be blocked; about the need to check and install a new flash player, the appearance of erotic pictures and videos, etc.
  3. Opening arbitrary tabs and windows in the browser. Sometimes, such tabs open after a certain period of time and not noticeable to the user. You will see this tab when you close or minimize the main browser window.

How malware gets on computers?

The most common infection of the browser by a virus occurs through the user’s fault. Usually, many users do not even pay attention to which sites they sometimes go to, which programs they install (and which checkboxes they agree with).

  1. Installation of programs through the “installers” and “rocking” …

    The most common reason for the appearance of malware on a computer is the installation of programs through a small installer (an exe file of no more than 1 MB in size). Usually, such a file can be downloaded on various sites with software (most often on little-known torrents). When you run such a file, you are offered to start or download the file of the program itself. By the way, if you pay attention to the installation process – then in most cases you can avoid installing malware.

  2. Installing programs with malware

    Also, malware may be “bundled” in other software. When installing such programs, you should opt out of various browser add-ons that they offer to install. The main thing – do not press the button further, without familiarizing with the installation parameters.

  3. Visiting erotic sites, phishing sites, etc.

    There is nothing special to comment on. I recommend still not to go over all sorts of dubious links (for example, coming in a letter to the mail from strangers, or in the social networks).

  4. Lack of antivirus and Windows updates

    Antivirus is not 100% protection against all threats, but it still protects against most of it (with regular database updates). In addition, if you update regularly and the Windows OS itself, then you will protect yourself against most of the “problems”.

Ways to remove malware

If you “caught” a virus in your browser, how to remove it? In many ways, your actions depend on the specific virus that entered the browser. However, there are universal methods that help in such situations.

Automatic removal

This is the most convenient method of removing which is suitable for users who want to get rid of the virus as soon as possible. It is also convenient because there is no need for any special knowledge since modern programs are very easy to use.

Solution for Windows users: Performing an antimalware scan with Norton would automatically search out and delete all elements related to malware. It is not only the easiest way to eliminate malware, but also the safest and most assuring one.

Download Norton

Checking “hosts” file

Some viruses replace “hosts” file, writing in its version of the file strings that change your connection to the sites. As a result, when opening a popular site, you get to the scam site, made by analogy. This deceptive technique is called “phishing”. Cybercriminals use it to steal your personal data like passwords, bank information and so on.

  1. Go to C:\Windows\System32\drivers\etc
  2. delete malware virus

Check browser shortcuts

If your browser goes to suspicious sites after you launch it, and the antiviruses “say” that everything is ok – perhaps a malicious command was added to the browser shortcut. To check the shortcut, go to its properties (the screenshot below shows the google chrome browser shortcut).

Next, look at the full launch line – “Target” or “Object”. The screenshot below shows the line as it should look if everything is ok.

Clean the Windows registry from viruses

Cleaning the registry must be done in normal (not safe) mode. To get started, go to the registry editor:

  1. Press Win + R, enter Regedit and press Enter.
  2. Viruses and unwanted programs create entries in the registry to download or update their files when Windows loads. These entries are located in the HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER registry keys along the path /Software/Microsoft/Windows/Current Version in the Run and RunOnce folders. If these branches (Run and RunOnce) have registry entries that are responsible for malicious processes, delete them. To do this, right-click on the desired file and click Delete.

    delete malware virus

  3. After that, search for the names of malicious processes in the registry. In the Registry Editor, select Computer, and on the Edit tab, click Find. Enter the names of the malicious processes that you recorded and click on Find Next. Delete all found registry entries in which these processes occur. To do this, right-click on the file and click Delete. After each deletion, press the F3 key (re-search for malicious registry entries with the specified name). This action should be repeated until the registry editor detects any malicious entries for your search query. Be very careful, if you delete the system branch in the registry editor, the computer will stop working. After deleting all entries, close the registry editor.

If the above-mentioned methods didn’t help in eliminating the threat, then it’s better to rely on an automatic way of deleting malware.

Download Norton

We also recommend to download and use Norton to scan the system after malware removal to make sure that it is completely gone. The antimalware application will detect any vicious components left among system files and registry entries that can recover malware.
