Windows Defender Pro adware description

“Windows Defender Pro” deceptive advertisements have been taking over numerous victims’ computers. This title should be familiar to those who have been infected with any of the following computer parasites: (Systemscantools.com adware, Adsystemscan.com adware, or Adwaresystemwarning.com). Windows Defender Pro ads can appear on your screen if your computer was affected by an adware program, and you might see an annoying alert message whenever you open your Internet browser. Usually, such message states that Windows Defender Pro has detected malware on your system and that you need to react immediately. The scam message urges you to call a fake tech support number, but you should not decide to call it.

Remember that Windows Defender Pro adware is nothing but a potentially unwanted program (PUP) that seeks to trick inexperienced users into believing that computer security is at risk and force them to call the provided number. However, the 2-spyware research team can say that this support number can be a premium rate number, which can tear off a huge amount of money for a single call. That is probably the main reason to not fall for the fake warning message on your screen. Moreover, Windows Defender Pro ads can stop or pause your activities on the Internet, and this dubious process usually slows computer system down, too. Plus, as you already know that ads by Windows Defender Pro are misleading and do not state accurate information about your computer system, you might want to remove Windows Defender Pro PUP from the PC. For that, we recommend installing Reimage spyware and malware removal program. You can scan your PC with it and easily remove the detected dangers.

Questions about Windows Defender Pro virus

For those who do not know how potentially unwanted apps are usually distributed, we can say that the developers of such programs use tricky techniques to spread their products in an indirect way. Bundling is the most common spyware distribution method, as it allows to attach the PUP to another free program without notifying the computer user. The only way to see if the program includes optional apps is to select Advanced or Custom installation option and see the further setup window. If you have downloaded a bundled software pack, then you should see a list of suggestions to get optional apps for free. What you need to do is to refuse to install them. You can do that by deselecting these suggestions. Simply remove the ticks that are checked in the boxes near such proposals, and then you can finish the setup without any worries.

If you have already noticed Windows Defender Pro alerts on your screen, you must remove the adware program that generates and sends them to you. To learn how to do it, proceed to the next page.
