How to uninstall the Power Blocker extension?

Also Known As: Ads by Power Blocker
Type: Adware
Damage level: Medium

What is Power Blocker extension?

Power Blocker is advertised as an extension that blocks advertisements. Ironically, this application generates revenue for its developers by generating advertisements. Also, it reads and changes data while users browse the web. Users rarely install adware knowingly. Thus, this and similar apps are called potentially unwanted applications (PUAs).

Power Blocker pop-up redirects

Power Blocker adware in detail

The main purpose of adware-type apps like Power Blocker is to display advertisements, for example, pop-ups, coupons, banners, surveys. Those ads are often designed to questionable pages. In some cases, they can cause unexpected downloads or even installations by executing certain scripts.

Ads displayed by Power Blocker could open download pages for other potentially unwanted applications, scam websites designed to extract money, personal information, and so on. A couple of examples of pages that Power Blocker's ads could open are "Win The New iPhone 12", "Code 0x03A10 (0E10)", and "McAfee Tollfree".

More information about Power Blocker

Additionally, Power Blocker could be designed to collect information that could be monetized by selling it to third parties, using it for marketing purposes, stealing identities, personal accounts, and so on. This app should not be trusted. More adware examples are BettingSiteDefender, Green Blocker, and BadURLDefender.

How did adware install on my computer?

Lots of potentially unwanted applications are distributed by bundling them together with other programs. Users agree to download or install PUAs when they do not change "Manual", "Custom", "Advanced", or other options that downloaders or installers have.

Also, PUAs are distributed through fake installers (like the fake Adobe Flash Player installer) and advertisements designed to run certain scripts. Users download fake installers from untrustworthy, deceptive web pages.

How to avoid installation of potentially unwanted applications?

Applications, files should be downloaded only from legitimate, official websites. Downloads from unofficial pages, third-party downloaders, and other sources can be used to distribute PUAs. The same applies to third-party installers. Downloaders and installers that have settings like "Custom", "Advanced" (or checkboxes) should be checked for unwanted offers.

Advertisements displayed on untrustworthy websites should not be clicked as well. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
