This item has the detailed directions on Defend Search uninstallation from your machine and the popular browsers.

Defend Search

Defend Search virus is a thing that you surely do not want to have on your hard drive. Everybody might go along with this, but here is a thing we want to explain you. Did anybody tell you that except showing ads, the advertising program presents more dangerous functions, which might be activated in a blink of an eye? Defend Search can spy on a customer, nick credentials, fulfill all kinds of unwanted activity from the user’s PC, etc. Usually, suchlike functions aren't working, as the basic virus' activity is more proficient for fraudsters. It's just an undesired program inside your machine, capable of creating and executing commands. We suggest you uninstall Defend Search immediately as every day that it works on your computer could be the one when the device doesn't boot at all. Here, we will explain to you how Defend Search functions, which purposes it runs after, and how you can get rid of it.


What is Defend Search

Defend Search is the utility that you should not ignore. It’s not dangerous on its own, but while it’s within the computer, you should be extremely watchful with what you're doing in the Net. Any site you visit and any banner you see becomes potentially perilous if you have Defend Search in the system. The Net isn’t a secure field even if the PC is clean as a whistle, yet with the virus, it grows noticeably more dangerous. Adware delivers you banners, but the fraudsters do not have goods for sale, so they don't bother whether you will buy any stuff or not. They do not even care about anything, despite the initial click on the banner, and when you did it - you're useless for them. In case you’re an operating user of the Web – swindlers receive approximately a dozen effective clicks from you daily. Each of these clicks is either a risk to download another adware, or a coin passed to scammers’ pockets from advertising companies.

We know two easy types of activity that web-criminals can perform via a functioning adware, such as Defend Search. While they’re distributing banners, they do not only advertise something. There are more goals, and we will explain them to you:

  • First of all – fraudsters show ads. If someone has a crude site which any of the major search providers declined to promote because of something – he can ask for swindlers’ assistance. They can redirect thousands of visitors to it each day. They won’t stay there for long, but at least the user counter will have something to show.
  • Hackers want to advertise other viruses. It’s much more perilous than to see the suspicious pop-ups in your browser. Every banner is a direct download of a virus or a crude tool that is going to live for months in the system, consuming free disc space and computer's recourses, starting when the computer loads and doing nothing. There's even a chance to get ransomware through such way, so do not ignore the danger of adware.

We hope that we've made it obvious to you that any advertising program is not to ignore – it’s a virus that has to be eliminated. In case you consider it for a long time – you'll finish with the laggard, dumb computer which needs minutes to open any program.

How to protect the computer

As a regular advertising tool, Defend Search has its habits and abides them strictly, as each virus does. It is being distributed via the bundled installation or just from its web page, so to outthink it you should use these hints:

  • If you're going to download an unpaid utility – get it only from its official website, but not from the file-sharing sites.
  • Never use utilities whose function is unclear to you.
  • Under any circumstances, do not ignore any information during the installation of an unpaid utility without knowing their content.
  • Keep your AV-tool working and up to date. It might save lots of your energy and time.
  • You shouldn't use anything that you’ve been suggested to download. Especially if it was suggested in the form of a pop-up ad that appeared in the browser.

The written above rules are plain but highly effective. You will not experience Defend Search ever again if you follow them.
