Potential Virus Alert for Mac

Potential Virus Alert for Mac is practically no different from most other browser hijacker applications. Same as the rest, the developers of Potential Virus Alert for Mac have designed the software with the intention of profiting from the myriads of displayed ads.

When we browse the web, we usually encounter a lot of advertisements, and this is perfectly normal. Being bombarded with an unstoppable flow of ads, banners, popping boxes, new tabs, and automatic page redirects, however, is not how it’s supposed to be, and can sometimes be the result of the presence of specific software on your computer. This type of software is known as browser hijackers, and Potential Virus Alert is a typical representative of the browser hijacker category. Developed with the purpose of displaying as many ads as possible, and redirecting you to as many sponsored pages as possible, this program may frequently annoy you and interrupt your normal browsing activity. That’s probably why you’ve landed on this page while seeking salvation from the disturbance.

What is Potential Virus Alert?

Potential Virus Alert is generally seen as what some may call a potentially unwanted program or PUP. This is because although Potential Virus Alert is not in and of itself harmful, it can often be involved in different unsavory practices and may have unwanted negative side effects in the long term. 

There are many (mostly free) programs that can come with a functionality that generates ads. Most of them typically provide users with some useful service or a feature for free. In the case with browser hijackers, however, the aggressive generation of ads is the dominant activity, which typically outshines any free service or feature that may come with the program. The reason is that there’s a different purpose of these programs – they are developed to generate income for their developers through sponsored ad-positioning.

Each click on any of the displayed ads turns into income through remuneration methods such as Pay-Per-Click, and the more clicks the ads can get, the higher the income. This explains why the moment a program like Potential Virus Alert gets installed in the system, dozens of pop-ups, links, ads, banners, and redirects to sponsored pages start bombarding the users through their screen. The good news is there’s a way to remove them permanently, and we’ll show you how to do that in the next lines.

The Potential Virus Alert app

The Potential Virus Alert app is often bundled in the setup of various free applications. And the developers of software like Potential Virus Alert app usually rely on users not paying close attention to the setup of these applications, which is how they end up installing the bundled components as well. 

If Potential Virus Alert or a23-trk.xyz is acting aggressively, don’t panic! While it’s on your computer, the ads’ intrusiveness may actually look like an infection with some strange virus. To your relief, however, browser hijackers do not contain harmful code, and are not intended to carry out malicious actions. That’s why, even though they can sometimes be really irritating, programs like Potential Virus Alert have nothing in common with malicious threats like Trojans, Ransomware or other harmful viruses. At their worst, hijackers can only expose you to unwanted commercials, and various websites, by taking over your homepage, or the main search engine.

This, however, may also hide certain risks, so, in general, it is not advisable to click on all the random banners, and pop-up messages that Potential Virus Alert may display. After all, you never know where the program may redirect you to and nowadays it often takes nothing more than a single wrong click to land some real malware.
