Checkosec.pro pop-ups that appear while browsing the Internet are a consequence of a malware activity that resides within your web browser. Such pop-ups emerge in abundant quantities, disrupting and annoying you.
The most of the pop-ups from Checkosec.pro site are not relevant to your choices, as it shows any marketing material it gets a contract for. Given that a lot of pages promoted in this way are not benevolent, it is clear to expect them to feature dangerous components. Specifically, they can throw you into diverse varieties of online frauds.
What are Checkosec.pro pop-up advertisements?
By some of the characteristics, Checkosec.pro pop-ups are comparable to standard pop-ups you may encounter on common sites. However, all the distinction – and harmfulness – arises from this exact website. Pages like Checkosec.pro are often established with sole objective – to offer unsuspecting individuals to enable pop-ups and then start spamming them.
Brief description of the Checkosec.pro pop-ups:

Ads by the Checkosec.pro site are not genuine either. At best, those will be entirely irrelevant ads, that will still be annoying taking into account their frequency. However, more common instances encompass advertisements of obscure deals with 90% off, adult sites ads or phishing attempts. Here are some of the traditional patterns for push ads spam:
- Your system is infected with 15 viruses. Contact our tech support or perform an immediate scan.
- You’ve received a new message on Facebook, Twitter, or WhatsApp. Beware of phishing links.
- Visit this new, totally legitimate shopping site and claim your 95% discount coupon.
- Sign in on this new crypto exchange website and receive a substantial crypto bonus.
- Discover 5 (10, 20, or even 50) women near you who are eager to chat.
- Speed up your computer with an incredibly effective system cleaner.
Due to the illicit marketing approach of Checkosec.pro, no legitimate corporations will really use their promotional offerings. Instead, the complete range of topics I’ve delineated above is managed by the same scammy individuals as those who are behind Checkosec.pro. Occasionally, upon clicking to the pop-up ad, you might be redirected to another page that proposes activating pop-up advertisements. The activity of multiple sources of pop-ups can transform your browser into an pathway of a pop-up surge.
Where did Checkosec.pro pop-ups come from?
The main and most common method to access the pop-up spamming site is to browse content on warez sites, pages containing pirated content, and similar platforms. The persons responsible for such dubious venues aim to offset expenses via redirects, often as a promotional strategy. This type of redirection is commonly known as an “anti-bot verification”.
A further plausible source of pop-up advertisements is adware, currently active within your system. It modifies browser settings in a manner so it starts displaying Checkosec.pro pop-ups without your consent. However, this situation is relatively uncommon, as such malware employs its own, more effective technique to showcasing advertisements.
Are Checkosec.pro pop-up advertisements dangerous?
Yes, they are. Initially, they can look safe – just a colourful pop-up that appears a couple times in an hour. However, the contents of this window differ sharply from what you generally see in pop-up notifications. Checkosec.pro site is controlled by crooks, who intentionally throw hundreds of irrelevant ads in pop-ups. They also don’t follow any manners of advertising and can launch sporadic push notifications into a storm of ads. For weak computers, that may be enough to make the system slower. But troubles are not over at this point.
As with any other thing related to illegal ads, Checkosec.pro push notifications do not contain any legit offers. Even when crooks make the ads looking similar to ones from Amazon, Walmart or Ebay, the web page these banners will throw you to are completely different. And these pages can offer you to turn on other pop-ups, install a “useful” program, or pay for a thing at a big discount and never receive it. Let’s leave aside the cases when pop-up advertisements promote phishing pages or straightforward malware. There’s no way these pages will bring you any good, thus interacting with them is a very bad idea. For the same reason, Checkosec.pro pop-up notifications are not recommended to click on either, and the best solution is to disable them as soon as possible.
How to remove Checkosec.pro pop-ups?
Fortunately, Checkosec.pro push notifications removal is not very complicated. They reside in the browser and can’t hide themselves in the system. Nevertheless, as I stated above, some push notifications may introduce malware to your computer. It is hard to show all of the cases, and manual attempts to remove malware is a bad idea. Thus, after removing the source of the pop-up ads the best option is to use anti-malware software. That is especially recommended in the case when you have never allowed pop-up advertisements, but they still appeared. This situation can point at malware activity. GridinSoft Anti-Malware will perfectly fit both recovery and malware scanning and removal purposes, because of its abilities of system recovery and superb detection system.

When the browsers are reset, you need to ensure that your browser will connect the right DNS while connecting to the website you need. Create a text file titled “hosts” on your pc’s desktop, then open it and fill it with the following lines2:
# Copyright (c) 1993-2006 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handle within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
Find the hosts.txt file in C:/Windows/System32/drivers/etc directory. Rename this file to “hosts.old.txt” (to distinguish it from the new one), and then move the file you created on the desktop to this folder. Remove the hosts.old from this folder. Now you have your hosts file as good as new.
