What is ConstaSurf?

ConstaSurf is a known form of adware, a type of malicious software that runs on your computer to display unwanted advertisements without your consent. ConstaSurf is considered a web browser add-on: it is installed without your knowledge as a plug-in or extension in your browser.

After installation, ConstaSurf starts showing unwanted ads when you surf the Internet with your browser. This type of adware does not just display ads, but can also redirect you to other malicious websites and constantly display annoying pop-up ads.

The most common methods by which ConstaSurf can enter your browser are by accidentally clicking on “sponsored links”, installing legitimate software bundled with this type of adware, or installing an infected browser plug-in or plugin. ConstaSurf can also infect your computer if you open an email attachment or download a program already infected by ConstaSurf.

Once your computer is infected by ConstaSurf, it will immediately start behaving maliciously. Along with displaying unsolicited advertisements, ConstaSurf may ask you to install fake software updates or submit your personal and sensitive information for collection.

At the same time, adware such as ConstaSurf can also change your browser settings. It is common for browsers infected by ConstaSurf to change their default settings in an unwanted way. In extreme cases, ConstaSurf can cause very serious damage to your system by manipulating the Windows registry and security settings on your computer.

What is adware?

Adware is a software application that displays advertisements during the execution of a program. The advertisements are provided through pop-up windows or bars that appear within the user interface of the program. Adware is often created for computers, but can also be found on mobile devices. The basic reason for adware is that it helps cover the cost of developing the program for the software developer and lower or eliminate costs for the user.

Adware generates revenue for its developer by automatically displaying commercial promotion in the software's user interface or on a screen that appears on the user's face during the installation procedure. You may also open new tabs, see a change to your home page, see results from a search engine you've never heard of, or even be redirected to an NSFW web portal.

How did ConstaSurf get on my computer?

ConstaSurf is sometimes integrated into free software (free software) that a user has downloaded from somewhere. After installation, the user has the option to continue using the software as is with commercial promotion or to purchase a version of the software without commercial promotion.

Software makers pay for ads to appear when you search for certain software. These ads will lead you to download software that may not even install the software you are looking for, but you will still get adware. So while you think all you get is decent free software, you really get a lot of ads.

At the same time replacing ads with its own and withdrawing money from search engines, the adware will also appear with even more questionable offers, such as asking you to install an "update" for Adobe Flash. All this for something that the customer can download for free from the appropriate site. No part of the proceeds goes to the free software developer; in fact, his fame has probably been damaged.

What are the symptoms of ConstaSurf?

If you suspect that your computer is infected with adware, look for any of the following signs:

  • Your browser suddenly runs slower than before and / or crashes very frequently.
  • Banners and advertisements appear on sites they have never had before.
  • Your home page has changed in some way and you cannot reset it.
  • Every time you want to visit a web portal, you will be redirected to a different page.
  • You will notice new toolbars, plugins or extensions in your browser.
  • Clicking anywhere on the page will open one or more pop-up windows.
  • Your computer starts installing unwanted applications without your permission.

Clean ConstaSurf from your browser

Even if the previous step worked for you, it is likely that the adware has already infected your browser and uninstalling the program will not remove the ads. To clean up the browser, basically restart your search engine (if it has changed) and look for extensions or add-ons that it doesn't recognize.

To reset the search engine:

  • Go to your browser settings and look for the search header. It should be in the general section.
  • From the drop-down menu, select the search engine you want to clean (for example, Google).

To search for an adware extension or add-on, I recommend that you use a third-party tool that displays all the extensions and add-ons from all your browsers in one window, including the hidden ones.

Use an anti-spyware program

Lastly, you probably need a anti-spyware program which runs in the background on your computer. It requires a program that can detect and intercept spyware when it tries to enter your computer; it should also be able to scan your computer for existing spyware and isolate it. Be sure to keep your anti-spyware program updated with new "definition files" on a daily or weekly basis to keep it working effectively. You never want to leave your computer unprotected and exposed to spyware or adware.
