PC users around the world are irritated by a new adware program. When it comes to advertising, the Greatdeals utility is a mastermind. In a sneaky way, it collects information about its victims and uses the data to terrorize them. It can cover your screen with all kinds of coupons, great deals, discounts and special offers.

Once on board, the Greatdeals adware will infect all your web browsers. Even ad-blocking apps won’t help you escape from the adverts. The Greatdeals utility is an actual program that is installed on your machine. It creates an ad-layer that forces ads on all opened websites. It will also hide its competitors’ advertisements. Thus, the malicious utility robs you from your free choice. You will lose idea about the current prices and become an easy target.

The Greatdeals adware uses the so-called pay-per-click marketing system. There is nothing bad in it, in fact, all big search providers use it. However, the Greatdeals utility exploits the system on a level that can be classified as an invasion of your privacy. Its owners will be paid for every ad you click on. Therefore, they will try to trick you into clicking as often as possible. To do so, they must choose ads that will be appealing to you. And they have found a solution for this problem. The adware will collect data about your online habits and use this information to select the right ads. In other words, the Greatdeals adware is spying on you.

What you are searching for online is not the only matter monitored by the Greatdeals adware. Your browsing history, favorite websites and bookmarks are no longer private. The malicious utility can steal your user names and passwords, too. The data will be sent to the owners of the tool. And they can do whatever they want with it. Including selling it to third parties. Can you imagine what a capable hacker can do with such data? You may become a victim of identity theft or lose money. Don’t risk your security. Act now and delete this pest immediately!

In the above paragraphs, we mentioned that the Greatdeals adware is installed on your machine, but do you remember doing it? It has permission to work on your system, there is no other way for it to operate. This can only mean that you gave it your approval. It is no surprise if you don’t remember doing so. The adware tricked you. It may have arrived in a bundle. The “bundling” method is a commonly used technique for adware distribution. To get some extra money, developers tend to hide additional programs under custom/advanced buttons or tabs. They would also try to mislead the user into believing that the advanced installation is a suitable choice for IT gurus only. This is a low-class deception tactic.

There is nothing complicated in the advanced method. It is a step-by-step installation wizard, just like the standard one. The advanced option includes more steps, though. Those steps are the most important ones. Only by using the advanced method can the user see all extra apps and deny their installation. We strongly advise you to deselect all extras. Yes, those tools do look useful, but if you take a moment to consider the situation, you will realize that if you truly needed them, you would have downloaded them by yourself.

Of course, the Greatdeals adware may have used other distribution methods to sneak into your computer. Torrents, spam emails and corrupted links are commonly used schemes. Scammers often write on behalf of well-known organizations. They would steal logos and fabricate stamps to lure you into downloading an attached file. Before you even open an email, make sure you know who the sender is. If you receive a letter from an organization, visit their official website. There you will be able to find their contacts, including their official email address. Compare it with the one you have received a letter from. If they don’t match, don’t hesitate to delete the message. It is definitely a scam.
