“Ads by Coupon Jumbo” Extension poses a danger to your computer and the security of your personal information. Most adware is regarded as “virus-lite”. Mainly this is due to the fact that the advertisements are not that dangerous if left alone and especially if you have the patience to not get annoyed by the constant pop-ups and general slowness that is bound to plague your PC. However, this type of virus is notorious for it will try to trick you in numerous ways so that you grant it access to your system and if this happens then you might find yourself in real trouble.

How and why is “Ads by Coupon Jumbo” Extension on my device?

You probably contracted it via a package installer, whether be it a freeware program you installed or something else like a codec pack for instance.

There is a way to prevent this from happening in the first place – always select advanced installation options and carefully choose what you wish to be installed on your PC.

Who creates Adware and how do the creators benefit from it?

The reason for adware creation is so the unsuspecting user, i.e. you, will be a part of a not so above the board website promotion. That’s right, you are being forcefully redirected to websites whose owners allegedly paid the malware creators so that they can promote said websites in a less than legal way. It doesn’t matter what the advertisement reads, the endgame here is you visiting a certain website. Why would they do such a thing you might ask. Well for starters it’s not that hard, adware is mostly similar with just the target website being the difference. Secondly for all we know this is cheaper than advertising in a proper way through Google Ads for example. There is a catch though and you should be alert and do your best to remove “Ads by Coupon Jumbo” Extension from your system as quickly as you can. The adware creators know that you will want to get rid of the virus sooner or later, that’s why roughly one third of the redirects you will be experiencing will not be towards the target website but to other websites where you might get infected by additional adware or even worse threats.
