How to eliminate the advertisements delivered by onemacusa.com?

What is onemacusa[.]com?

Similar to dnsvibes.co, othemyinetere.space, s1-n.com, totaltopposts.com, and thousands of others, onemacusa[.]com is a rogue site that presents visitors with questionable content, pushes its browser notifications, and/or redirects users to various (likely unreliable/malicious) websites.

Rogue pages are typically accessed via redirects caused by untrustworthy sites, intrusive adverts, or installed PUAs (Potentially Unwanted Applications).

Onemacusa[.]com in detail

The behavior of onemacusa[.]com is determined by its visitors' geolocations, which the website learns from their IP addresses. In other words, this information dictates whether visitors are presented with dubious material and/or get redirected elsewhere.

Onemacusa[.]com also uses fake CAPTCHA verification to trick users into allowing its browser notifications. Nearly all rogue webpages use deceptive content/instructions for this purpose. Should the notifications be allowed, onemacusa[.]com will start running intrusive advertisement campaigns.

The displayed adverts endorse suspect and malicious websites. Furthermore, some intrusive ads can infiltrate software (e.g., PUAs) into systems - when they are clicked on.

Potentially unwanted application overview

PUAs appear legitimate and offer "handy" functionalities, which are usually nonoperational. However, unwanted apps can have harmful abilities, e.g., force-opening pages, running intrusive ad campaigns, hijacking browsers, and collecting sensitive data. To summarize, PUAs can cause system infections, severe privacy issues, financial losses, and even lead to identity theft.

How did adware install on my computer?

PUAs are spread using the "bundling" method - packing ordinary programs with unwanted or malicious additions. Rushed downloads/installations increase the risk of allowing bundled content into the device. Intrusive adverts are also used to proliferate PUAs. Once clicked on, the ads can execute scripts to make downloads/installations without user consent. Some PUAs have "official" promotional/download webpages.

How to avoid installation of potentially unwanted applications?

It is recommended to always research software download it from official/verified sources. Untrustworthy download channels, e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, and other third-party downloaders - often offer bundled/hazardous content.

When downloading/installing, it is advised to read terms, study possible options, and use the "Custom/Advanced" settings to opt-out from all additions. Intrusive advertisements appear harmless; however, they redirect to unreliable and dubious sites (e.g., pornography, gambling, adult-dating, etc.).

In case of encounters with such adverts and/or redirects, the system must be checked and all suspicious applications and browser extensions/plug-ins detected - immediately removed from it. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
