What is BadURLDefender?
BadURLDefender is a browser extension endorsed as a tool capable of preventing malicious websites from being opened. It is classified as adware and operates by running intrusive advertisement campaigns. Additionally, it spies on users' browsing activity. Due to the questionable methods used to distribute adware-type products, they are also categorized as PUAs (Potentially Unwanted Applications).
BadURLDefender adware in detail
Adware enables the placement of various pop-ups, banners, coupons, and other ads on any visited website and/or different interfaces. The delivered advertisements diminish the browsing speed and overlay webpage content. Furthermore, intrusive adverts promote untrustworthy and malicious websites. What is more, some of these ads can infiltrate software (e.g., PUAs) into systems - when they are clicked on.
BadURLDefender has data tracking abilities. Targeted information includes: URLs visited, pages viewed, search queries typed, IP addresses, personally identifiable details, and so on. The collected data is then shared with and/or sold to third-parties.
In summary, the presence of unwanted software on devices can lead to system infections, serious privacy issues, financial losses, and identity theft. Therefore, it is recommended to remove all suspicious applications and browser extensions/plug-ins immediately upon detection.

Adware in general
NetflixHub, Flow, and Youtube Ad Blocker are a few examples of adware. Like nearly all PUAs, adware appears legitimate and offers "handy" features that are seldom operational. Unwanted apps can run intrusive advert campaigns, cause redirects, hijack browsers, and collect private data - instead of delivering on any promised functionalities.
How did BadURLDefender install on my computer?
Some PUAs (e.g., BadURLDefender) have "official" promotional/download webpages. These applications are also proliferated through intrusive ads. Once clicked on, they can execute scripts to make stealthy downloads/installations.
PUAs are mainly distributed via download/installation setups of other programs (i.e., the "bundling" marketing technique). Hence, rushed download/installation processes increase the risk of allowing bundled content into the system.
How to avoid installation of potentially unwanted applications?
It is recommended to research software and download only from official/verified sources. Untrustworthy download channels, e.g., unofficial and freeware sites, Peer-to-Peer sharing networks, etc. - often offer bundled and hazardous content.
When downloading/installing, it is crucial to read terms, explore available options, use the "Custom/Advanced" settings to opt-out from all supplements. Intrusive advertisements appear legitimate; however, they redirect to highly questionable websites (e.g., adult-dating, pornography, gambling, and so on).
In case of encounters with such adverts and redirects, the system must be checked and all suspect applications and browser extensions/plug-ins detected - removed from it without delay. If your computer is already infected with BadURLDefender, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
