There is a new variant of adware that has been infecting many unsuspecting victims. Using the typical tactics, Tthematt.xyz has been finding its way to take over browser settings and bombard victims with annoying ads. Tthematt.xyz uses a bogus CAPTCHA to fool users into hitting the “Allow” button, which then opens two or three dubious websites. Users are extremely unlikely to open Tthematt.xyz on purpose.

Visitors to Tthematt.xyz are asked to press the “Allow” button to prove that they are not robots, according to a notice displayed on the site. This is one of the many clickbait strategies used by sites like Tthematt.xyz to persuade visitors to accept their alerts.

Tthematt.xyz sends out notifications to advertise Potentially Unwanted Applications (PUAs) that are likely to hijack browsers, display adverts, and collect any information they can from their victims. These alerts can also be used to advertise various scams aimed at tricking visitors into revealing personal information.

Things to Avoid When Browsing the Internet In Order to Be Safe From Adware

Although the internet is free and can be used privately, there are things that you should avoid doing if you don’t want to be infected with Tthematt.xyz or any other online threats. Here are some internet browsing habits that you should avoid doing if you want to be free from Tthematt.xyz.

  • DO NOT Download or Install Pirated Apps – Another method used by cybercrooks to access a victim’s computer is to disguise their app as a legitimate one. They will make the application look identical to the original, using the same colour theme, fonts, and logos, making it difficult to distinguish between the two. As a result, you should refrain from obtaining and installing pirated software from dangerous websites.
  • DO NOT Click on Suspicious Ads and Notifications – When you click on a suspicious ad or notification, there is a chance that you are allowing it to perform anything it wills on your computer. With the case of Tthematt.xyz, when you click “Allow” on its notification, it will then make changes to your browsers such as changing the homepage, default search engine and a lot more.
  • ALWAYS Read the Installation Agreement – The term “software bundling” refers to the practice of combining many applications into a single installer package. This tactic is used even by genuine programs as well, therefore we strongly suggest reading the installation agreement carefully and opt-out of anything that asks you whether you agree to install an additional application.

Here’s an example of how software bundling may look like:

Software Bundling Example

As you can see in the examples, the bundled application has a checkmark next to it by default, indicating that if you click next, it will be installed automatically. That is why you must carefully read the installation agreement.
