Removing viruses from browsers

The most needed, often used programs on a computer / laptop are different browsers. Through them, the user enters the Internet, receives, downloads information, distributes, and sends to other users. Therefore, viruses have appeared that hit the point of the browser exactly, without affecting other programs. Antivirus programs often do not notice such viruses; meanwhile, the user gets a lot of advertising because of them, pop-up banners, the operating system slows down, transitions to the desired site are blocked, and redirects to other sites. These and other problems associated with browser viruses can be fixed by clearing Yandex, Google Chrome, IE and other browsers. Let's take a look at what an advertising virus is in browsers, how to remove it safely, effectively.

Symptoms of infection

There are many, let's call the most common.

  • The emergence of intrusive advertising banners, teasers, links with offers to sell or buy. And advertising occurs on the pages of sites where previously it was not.
  • There are requests to confirm some information with tips, requests to send SMS to short numbers on various websites, including popular ones (the virus replaces the website address).
  • The emergence of multiple windows with messages about imminent blocking.
  • Exit windows with a message about the need to check and install a new flash player.
  • Opening in the browser of various erotic pictures, video.
  • Tabs, windows in the browser open arbitrarily, often imperceptibly, you can see the tab only after closing the main browser window.

Ways of infection

  • Typically, an infection occurs when downloading programs using installer files with the .exe extension. By running the installer, you see the offer to install the program itself or to download it, at the same time you get several modules, add-ons.
