Upon pressing OK, users would be presented with a threatening message, claiming that multiple viruses have already infected the system and that some of it are damaged.

Do not get tricked by software bundle packages and avoid adware infiltration

Experts[3] say that there are two different ways how adware might have ended up on your computer: you either installed it along with other software from third-party sites or you installed it deliberately without known that the app is ad-supported. If the latter is the case, we advise you to read up program reviews online before downloading anything, as they can often indicate if the app engages in dodgy practices post-installation.

Whoever, in most of the cases, users install PUPs with freeware, as they rarely pay close attention to the installation process of new programs. Unfortunately, but third-parties are happy to abuse this fact and often insert optional components into a single software package. While there is nothing illegal about offering users promotions, the way it is done matters a lot.

Unsolicited installation of software is something that is considered to be malicious behavior. Nevertheless, third-parties often can disguise by claiming that all the information was presented during the installation – and, technically, they will be correct. Software bundling often uses pre-ticked boxes, deceptive deals, misplaced buttons, and other techniques to make users miss the PUP. This way, they install adware on their systems without realizing it.

To avoid that, you should always pay close attention to the installation process of third party applications – uncheck all the boxes, decline all the deals, watch out for deceptive button placements and always opt for Advanced/Custom settings. Another important step is to stay away from pirated software and cracks – these can result in such dangerous threat infections like ransomware.[4]
