Click Subscribe Calendar Spam

Click Subscribe

Click Subscribe is an unwanted app that attaches to the browser and generates ads and page-redirects during the user’s online sessions. Click Subscribe also introduces various changes in the browser, some of which might make the system unstable or expose it to malware.

If you have encountered Click Subscribe in your browser, some of the first things you’ve probably noticed are changes made to the starting page and the new-tab page of the browser, as well as to its default search engine tool. The toolbar of the browser could also have been affected by Click Subscribe by either having been replaced entirely or by having had some new buttons added to it. Such unwelcome and unauthorized changes can take place in pretty much any browsing program that you might have in the computer. Even some of the safest browsers such as Google Chrome, Mozilla Firefox, and Microsoft Edge can get such an app installed in them without the user’s informed approval. In fact, those are the browsers that get the biggest number of hijackers because they are the ones that most people use.

What is the goal of Click Subscribe?

Unlike real malware programs and viruses such as Trojans, Worms, Spyware, or Ransomware, it is not typical for an app like Click Subscribe to cause any direct harm to the computer it is installed in. The type of apps to which Click Subscribe belongs is known as browser hijackers and hijacking the computer’s main browser is what they do. This means that they take over the settings of the browsing program, introduce some changes to them, and then use those changes to spam the screen with different kinds of online advertisements and page-redirects. The end-goal is to make money through online advertising. Understandably, the more the users who get exposed to this form of aggressive advertising, the greater the financial profit for the creators of the hijackers. This is why these apps are so common and why they typically get installed in stealthy ways, using file-bundles, spam messages, clickbait download buttons, and other similar techniques.

Nevertheless, regardless of how irritating and obnoxious an app like Click Subscribe could be, it would still typically not cause harm to the system. That being said, the presence of a browser hijacker in your Windows computer could actually contribute to a decrease in your PC’s overall safety, which is something that you must not ignore if you wish to keep the computer away from harm.

Potential dangers related to browser hijackers

The biggest security problem that could come from an application like Click Subscribe is the possibility of you getting exposed to questionable online locations and content that might be unsafe. This is mainly due to the endless spam with adverts, pop-ups, automatic page-redirects, and other similar forms of aggressive advertisement. As you probably know, many of the ads found on the Internet are actually disguised links to questionable sites, some of which might even be hosted by hackers and used for Ransomware, Trojan Horse, or Spyware distribution. In other cases, you might land on phishing pages that try to obtain sensitive details about you by presenting themselves as legitimately-looking sites. To avoid such encounters (or at least decrease their likelihood), we strongly recommend that you take a look at the removal steps below and follow them in order to uninstall Click Subscribe and remove any data it might have left in your computer.

Click Subscribe Calendar Spam

First you need to close all pop-ups that are currently open.

  • If the pop-up has a checkbox named “Don’t show more alerts from this webpage” click on the checkbox before closing the Ad.
  • If a Block Alerts button happens to appear after you shut down a pop-up on your iPhone, iPad, or iPod touch tab that button to stop receiving alerts from the same page.

In case that a pop-up fails to close after performing the above operations:

  • On your Mac you should make your Safari browser close forcibly by pressing Command-Option-Esc. Select Safari from the list of Apps and force close it. After you force close it you need to restart Safari, but please hold the shift button while it starts. This will prevent any pesky Ads from opening automatically.
  • On your iPhone, iPad, or iPod touch you can do the same by pressing the home button twice in a quick succession. You’ll then see a preview of all apps that have been recently used. Swipe left to find Safari and then swipe up on the app’s preview to close it forcibly In order to prevent Safari from opening unwanted windows on startup go to Settings->Safari and Clear History, as well as Website Data. This will also clear your browser history and cookies so keep that in mind and export them if you want to keep them.

Choose Preferences from the Safari menu. Then do the following:

  1. Select the Security icon and then click on “Block pop-up windows“. This should stop many types of pop-ups from appearing.
  1. Next check on your homepage and the settings for the search engines. Adware likes messing with those. We can not provide more specific instructions for this, as you may be using many different browsers.
    • Select the General icon and look at the Homepage field. It should either be empty or filled with the address of the Homepage you want.
    • Follow up on the Search icon. Again it should be either the default search engine or any that you have set for yourself. Note that in some versions of Safari these settings are found in the General panel/

Open Safari and click on the Extensions button. Note that Adware use extensions almost exclusively to inject the pop-up Ads into your browser. Any extension on this list that you do not remember installing yourself is likely planted there by the Adware. Remove ALL extensions you are unfamiliar with.
