Splending Mini-version Truetest

The Splending Mini-version Truetest is an adware that displays pop-ups and unwanted advertisements on any visited Web pages. The advertisements are shown in boxes that contain coupons, with underlined key words made as in-text advertisements, advertising banners, and pop-up ads as part of its injecting of ads into any website. The Splending Mini-version Truetestmay be part of bundles of free programs that may be downloaded off the Internet. Some of the free download bundles out there do not share what their contents are accurately so that they may end up installing other software, most commonly adware, Bitcoin miners, browser hijackers and more. In such cases, the users may find themselves surprised unpleasantly with a freshly-installed Splending Mini-version Truetest without their knowledge.

Once the Splending Mini-version Truetest ends up installed, whenever users end up browsing the Web, they will experience redirections to other websites and unwanted advertisements during their browsing sessions. The ads are aimed at promoting additional content and its installation, one of questionable origin, such as optimization utilities, browser toolbars and more, all in the name of a pay-per-click source of revenue for the adware publisher. The authors identify themselves under the nickname marina.hamidulina87 in the Google Chrome Store page of the Splending Mini-version Truetest.

The adware's advertisements may appear with different text under the pop-up, such as 'Powered by Splending mini-version truetest,' 'Ads powered by Splending mini-version truetest,' 'Brought to you by Splending mini-version truetest,' 'Ads by Splending mini-version truetest' and 'RocketTab powered by Splending mini-version truetest.'
When a computer is infected with the Splending Mini-version Truetest adware, its presence can be deduced through the following symptoms:

• Banner advertisements injected into pages during browsing sessions.
• The activity of affected users on the Web being tracked.
• Turning random Web page texts into hyperlinks.
• Additional adware also may be installed on the affected computer automatically.
• A slowdown in the browser operations or even a tendency to freeze when loading pages on some machines.

Digital Signatures

This section lists digital signatures that are attached to samples within this family. When analyzing and verifying digital signatures, it is important to confirm that the signature’s root authority is a well-known and trustworthy entity and that the status of the signature is good.
