What are Defenderlab.xyz pop-ups?

Defenderlab.xyz popups are an effect of adware activity. Adware is a type of malware that demonstrates to you the pay-per-view of pay-per-click promotions, which creates a massive amount of revenue for adware distributors.

Pop-up promotions itself is an excellent, low-priced and really efficient marketing instrument¹. It allows the vendor to attach the customers’ interest to their website, and the customers to get the dynamic updates on the goods they intend to buy. When the consumer will receive a pop-up notification that the TV set he likes to buy is available at the online shop he/she visited previously with a 15% price cut, one will certainly use this opportunity and buy it. Taking into consideration the incredibly small cost for the popups and their targeting, such an advertising tool is a favourite thing amidst the marketing teams of big online stores.

Nonetheless, such a profitable strategy could not be missed by virus creators. Ability to demonstrate the popup advertisements by force to the targets of malware invasion is a great basis for evil-minded tricks with the popup ads.

Besides some “light” viruses, like adware or undesirable programs, you may additionally get something much more hazardous, like ransomware or coin miner; the large share of coin miners circulation is exactly after the malicious advertisements.

And it is very hard to distinguish the unwanted app from a good one, if you don’t know the exact names. Besides the PUPs and fake antiviruses, popup-related advertisements are also exploited as a distribution way by various trojan viruses, for instance – coin miners. The consequences of activity of such viruses is 100% unpleasant, and can cost you hundreds of dollars. And even if you are not tapping these banners, they can be clicked by whoever who also uses your PC – parents, children, spouse, etc. So the situation may become much more serious, and it will be much harder to deal with it without information loss.
