What are Maincaptchasource.com pop-ups?

Maincaptchasource.com popups are an outcome of adware presence. Adware is a type of malware that presents you the pay-per-view of pay-per-click advertisements, which creates a major volume of earnings for adware distributors. These ads may include sometimes shocking material, or have a web link to harmful content/website, considering that adware maintainers have no reason to examine the goodness of the content they are going to reveal – their solitary target is cash.

Pop-up advertising itself is an excellent, cheap and really successful advertising tool¹ It allows the vendor to attach the buyers’ attention to their website, and the customers to get the dynamic updates on the goods they want to purchase. When the person will get a pop-up notification that the TV set he desires to buy is provided at the online shop he/she checked out previously with a 15% price cut, one will definitely use this chance and get it. Taking into consideration the incredibly small cost for the popups and their targeting, such a marketing tool is a much-loved thing amidst the advertising departments of huge online stores.

However, such a rewarding strategy could not be missed by virus creators. Potential to show the popup advertisements forcibly to the victims of malware invasion is a perfect basis for evil-minded tricks with the popup ads.

All of these types of software are unsafe, due to the fact that it is quite simple to include a Maincaptchasource.com malware under the guise of part of the license hacking script, or as a component of the self-made algoritm inside of the Windows optimization tool.

Maincaptchasource.com popup malware may also be hidden in the ad somewhere on the unusual web page.

Besides some “light” viruses, like adware or unwanted programs, you may also get something a lot more dangerous, like ransomware or coin miner; the substantial share of coin miners distribution is exactly after the malicious promotions.
