This page aims to help you remove CastVPN “Virus”. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

In case that your screen has recently started getting swarmed with various kinds of irritating online ads while you are surfing, then the information that you will find on this page might be of use to you. The most likely reason for the constant ads-interruptions that you are probably struggling with is an Adware piece of software. Throughout the following lines, we will be focusing on one particular representative of this software category that is called CastVPN. In fact, if most of the ads that you see contain a small text stating something like “Ads generated by CastVPN” or “CastVPN supported ads”, then you are surely dealing with this particular application.

In case that you haven’t heard about Adware before, you should know that this is a type of software which tends to function like an add-on to popular browsers such as Microsoft Edge, Google Chrome, Mozilla Firefox or Opera and make them generate various kinds of sponsored and pay-per-click ads, pop-ups, links, tabs, page redirects and banners. Basically, the main reason for the creation of such applications is the need for ads exposure and on-screen promotion of different sites, software, services and products.

Fortunately, Adware is not among the most malicious and disastrous computer threats (like Ransomware, Trojans, Spyware, Worms, etc.). Yet, it seems that this software may oftentimes become a source of major online disturbance for a lot of users. For instance, an application like CastVPN may quickly become very annoying. It may not try to do anything harmful on your system, but just the mere fact that it could constantly display various nagging and difficult-to-remove ads on your screen may be enough to make you wish to uninstall it.

Most security experts do not regard the Adware programs as actual malicious threats and such apps are actually commonly distributed for free in various web locations. Despite not being seen as a virus, however, this software may be quite tricky to uninstall. In most of the cases, a simple uninstallation from the Control Panel menu may not be enough to remove the intrusive ad-generating software. That’s why, if you are looking for an effective removal solution, we suggest you follow the instructions in the Removal Guide below or use the professional CastVPN removal tool posted on this page.

Why is it a good idea to remove the adware?

There are users who are not much bothered by the ads that CastVPN may generate. In fact, this application may display some good offers and relevant links which might be matching your latest searches and interests. So, if you don’t find the adware as aggressive and irritating, that is totally fine. However, you may like to know what the effects of keeping this software on your system might potentially be if you decide to let it operate on your PC. For instance, apart from the ads generation, an application like CastVPN may sometimes initiate automatic page-redirects to different third-party websites, links and new tabs. This activity may not be that bothering to some of you, but you should also consider the risk of getting redirected to some unsafe or misleading web locations. Naturally, the chances of getting exposed to unsafe advertising materials are going up if there is an ad-generating software on your system. Moreover, one of the most common methods that the criminals use to infect the web users with Ransomware, Trojans and other nasty viruses is through fake ads and Malvertising. That’s why, we generally do not advise our readers to click on anything that gets displayed on their screen and recommend that they uninstall any software which prompts them to interact with unfamiliar content.

How to protect your PC from Adware in the future?

There are some basic rules for online safety and despite the fact that applications like CastVPN don’t fall in the category of computer any malicious threats, we would still like to remind you to be cautious when you browse the web. Most ad-generating and page-redirecting applications can be found inside different email attachments, free download links and software bundles, torrents, ads, ad-supported websites, automatic installation managers or fake online update requests. That’s why, if you intend to install some new software on your PC, you should carefully read its EULA, inform yourself about the presence or absence of any additional or ad-supported components and select the installation options that allow for more customization (usually those would be the Advanced/Custom/Manual ones). Do not hesitate to uncheck any pre-selected or “recommended” applications which have no relation to the program that you actually want to install. Otherwise, you may end up with some potentially unwanted applications which may alter your browser settings and disrupt your normal web activities.
