How to remove Pureweb adware and the ads it displays?
Written by Tomas Meskauskas on (updated)
What is Pureweb?
Pureweb is an adware-type browser extension. In contradiction to what this software is promoted as - an adblocker - it runs intrusive advertisement campaigns. Due to the dubious methods used to distribute adware products, they are also classified as PUAs (Potentially Unwanted Applications).
Pureweb adware overview
Adware can display intrusive advertisements (e.g., pop-ups, coupons, banners, etc.) on visited sites and/or other interfaces. The delivered adverts diminish the browsing experience and endanger device/user safety. The ads endorse various untrustworthy, deceptive/scam, compromised, and malicious websites. Furthermore, some intrusive advertisements can download/install software (e.g., PUAs) without user consent - when clicked.
Pureweb also has data tracking abilities. The gathered information (e.g., browsing and search engine histories, personally identifiable details, etc.) is monetized by being shared with and/or sold to third-parties. In summary, the presence of unwanted software on devices can lead to system infections, severe privacy issues, financial losses, and even identity theft.

Adware in general
Page Ranking Tool, AdBlock Master, Museum Explorer, and Cent Browser are some examples of adware. This software looks harmless and offers "handy" functionalities. However, the functions rarely work as promised, and in most cases - they do not work at all.
In fact, this is true of nearly all PUAs. Unwanted apps are designed to run intrusive advert campaigns, force-open dubious and malicious webpages, hijack browsers, and collect private information.
How did Pureweb install on my computer?
Select PUAs (e.g., Pureweb) have "official" promotional/download pages. These apps are also spread using the "bundling" marketing tactic - packing regular programs with unwanted/malicious additions. Rushed download/installation processes increase the risk of allowing bundled content into the system.
Intrusive advertisements proliferate PUAs as well. Upon being clicked, the ads can execute scripts to make stealthy downloads/installations.
How to avoid installation of potentially unwanted applications?
It is recommended to research software and only download from official/verified channels. Untrustworthy sources, e.g., unofficial and freeware websites, Peer-to-Peer (P2P) sharing networks, etc. - often offer bundled/harmful content.
When downloading/installing, it is advised to read terms, study available options, use the "Custom/Advanced" settings, and opt-out of all additions. Intrusive adverts look harmless yet redirect to various questionable sites (e.g., gambling, pornography, adult-dating, etc.).
In case of encounters with such ads/redirects, the system must be checked and all suspicious applications and browser extensions/plug-ins detected - immediately removed. If your computer is already infected with Pureweb, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
