Ads by External Source

What is External Source?

External Source is a potentially unwanted program (PUP) that employs a deceptive software marketing method called 'bundling' to install on Internet browsers (Internet Explorer, Google Chrome, and Mozilla Firefox) without users' consent. Therefore, External Source is categorized as adware.

Bundling is a way to install additional software together with the users' chosen software, and consequently, users often inadvertently infect their systems during download of free software from freeware download websites.

After successful infiltration, External Source adware delivers various intrusive online advertisements such as pop-up, banner, in-text, etc. Be aware that advertisements generated by External Source may lead to high-risk adware or malware infections.

External Source collects various software and hardware information (for example, IP addresses, websites visited, pages viewed, and search queries) that may be personally identifiable. There is a high probability that this information tracking will result in serious privacy issues.
