Pop-up promotions itself is a very good, affordable and very efficient advertising tool1. It permits the vendor to link the customers’ attention to their website, as well as the buyers to get the dynamic updates on the goods they want to buy. When the person will receive a pop-up alert that the TV set he likes to purchase is available at the online store he/she checked out previously with a 15% discount, one will surely use this opportunity and buy it. Considering the incredibly low cost for the popups and their targeting, such a promotion and marketing instrument is a much-loved thing amidst the marketing departments of huge online retail stores.

However, such a rewarding plan could not be missed by malware developers.

A lion’s part of this virus cases is after the freeware or cracked programs, that are spread on the peering networks.

All of these types of applications are risky, because it is extremely simple to include a Maincaptcha.top malware under the guise of part of the license hacking script, or as a part of the self-made algoritm within the Windows optimization tool.

Maincaptcha.top popup malware can also be concealed in the advertisement somewhere on the odd website. Such sites are in most cases full of colorful and blinking ads, and their proprietors often permit any type of promos to be published on their page.

Besides some “light” viruses, like adware or unwanted programs, you can also get something much more damaging, like ransomware or coin miner; the large share of coin miners circulation is exactly after the malicious ads.

And it is pretty hard to distinguish the undesirable app from a legit one, if you don’t know the exact names. Besides the potentially unwanted programs and dubious antiviruses, popup-related advertisements are also used as a distribution method by various trojan viruses, for instance – coin miners. The consequences of actions of such viruses is 100% unwanted, and can cost you hundreds or even thousands of dollars.

When the browsers are reset, you need to ensure that your browser will definitely connect the appropriate DNS while connecting to the website you need. Create a text file titled “hosts” on your computer’s desktop, then open it and fill it with the following text3:

# 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.

# 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handle within DNS itself.
# 127.0.0.1 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.

Browser will stop reacting for ~ 30 secs, and afterwards it will be back to the normal, up until you try to open settings again.
