Pop-up advertising itself is a very good, affordable and also really effective advertising instrument¹. It enables the seller to attach the buyers’ attention to their site, and the customers to receive the dynamic updates on the goods they intend to purchase. When the customer will receive a pop-up alert that the TV set he wishes to buy is offered at the online store he/she saw earlier with a 15% discount, one will certainly use this opportunity and purchase it. Considering the very low price for the popups and their targeting, such a promotion and marketing tool is a favourite thing amongst the marketing teams of big online stores.

Nevertheless, such a rewarding plan could not be missed by malware creators. Ability to show the popup ads forcibly to the people of malware invasion is a perfect basis for malevolent adjustments with the popup advertisements.

When the web browsers are reset, you need to ensure that your web browser will definitely connect the proper DNS while connecting to the site you want. Create a text file titled “hosts” on your desktop, then open it and fill it with the following content³:

# 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:

# localhost name resolution is handle within DNS itself.

So, if you try to fix your browser settings after your machine was penetrated by pop-up-related malware, your browser will certainly collapse quickly. Sometimes, you will see no crash, but significant lag spike after pushing the “settings” key. Browser will stop responding for ~ 30 secs, and afterwards it will be back to the normal, until you try to open settings one more time.
