What is VK+OK AdBlock

Many experts consider VK+OK AdBlock to be an unwanted browser extension. Such an assumption is true as long as it runs suspicious activity without the consent of users. Initially, VK+OK AdBlock is the name of a Google Chrome extension available for download in the official store. Its main goal is to improve the browsing experience by blocking ads across all social media popular in Russia. However, despite it is able to perform this feature indeed, some actions taken by the extension are shady and do not consent users. At first, VK+OK AdBlock keeps sending information to its server in Russia even when users stop using any social media websites. This says there is a risk of data surveillance, which can be gathered by the developers and used in illegal needs. The second suspicious thing is why VK+OK AdBlock ads itself to the exception list of Windows Defender. Apparently, the extension has some security issues and does not want to be removed by the antivirus program. Lack of transparency, as well as unwanted distribution methods, puts VK+OK AdBlock onto the list of potentially unwanted extensions that should be removed from your system. It is also possible you see an additional stream of ads when VK+OK AdBlock is active. Despite blocking social media ads, it may not neglect the promotion of sponsored content across other websites whilst surfing the web. In order to delete it, follow the instructions listed below. You will also learn how such extensions can sneak into your system and what should be done to prevent it.

How VK+OK AdBlock infected your computer

Unwanted extensions can be promoted by adware programs that you can install by a matter of accident. Many developers promote third-party offers along with free software advertised on different resources. These offers may end up being adware or unwanted programs. Usually, they can be found lurking inside of “Advanced” or “Custom” sections. If there are such sections visible during the installation, you should expand them and deselect anything offered within. The promotional offers may be marked as something “useful” or even “legitimate”, but install software different from what you expected eventually, so better deselect them no matter the names. If you struggle to delete VK+OK AdBlock because it keeps coming back, then more likely your system is infected with unwanted software. To make sure you uninstall it correctly and without traces, follow our tutorial below. Step-by-step instructions will help you with that.
