Remember that the topic is classified as a PUP (potentially unwanted program). Without the user’s permission, it enters the computer. It has been observed that Viverridae is embedded in various freeware, shareware, and fake software updates in the majority of penetration incidents. The unwanted program quickly infiltrates the browser after a user installs such applications and makes unauthorized changes. The most noticeable is the virus’s control of the homepage, which will make unwanted search engine as the default option.
Viverridae is classified as a threat under the Adware category rather than the PUP category. This indicates that it was created with the intention of making money online by showing ads. Since it is a remake of CirrusCastellanus and Chromstera, it is expected that Viverridae’s advertisements will be obnoxious and come in the form of numerous pop-ups, redirections, and push notifications. The advertisements are also dangerous since they include malicious links that are intended to redirect browser pages to dangerous websites. Web users risk acquiring more malware or adware as a result of accessing the questionable advertisements.
