What kind of application is QuantityTopic?
QuantityTopic is an untrustworthy application designed to bombard users with annoying advertisements. Software of this type is called adware. Our team discovered QuantityTopic after using a fake installer downloaded from a page claiming that the installed version of Adobe Flash Player is outdated.
QuantityTopic adware in detail
Advertisements displayed by QuantityTopic can open potentially malicious pages. For example, deceptive pages urging to call fake technical support numbers, instructing to download shady applications, asking to provide sensitive information, etc. Moreover, those ads may be designed to run certain scripts to start unwanted downloads or installations.
Our team tested many apps similar to QuantityTopic and learned that some of them can read sensitive information. We found that they can read credit card details, passwords, browsing history, and other data. Their developers may misuse obtained data to steal identities, accounts, money, online accounts, etc.
Additionally, adware can have the properties of a browser hijacker. It can change the settings of a web browser to promote a fake search engine. In such cases, users are forced to browse the Internet using a fake search engine that can generate misleading results or show results generated by untrustworthy search engines.
