Browser is infected

“Browser is infected” is what experts identify as your typical browser hijacking program. As such, “Browser is infected” ‘hijacks’ your browser by taking over its main settings and causing the browser to behave in a predetermined manner.”Browser is infected” is specifically meant to target the browsers installed on Mac computers. And it therefore has the capacity to integrate with the vast majority of Mac-compatible browsing programs. So whether you’re using Chrome, Safari, Firefox or some other kind of browser, this particular hijacker will have no difficulty integrating with it. Then once that happens, you can expect it to start introducing some rather annoying changes to the browser’s appearance, as well as to the way it acts. For instance, the hijacker may install a new default search engine and replace the homepage with a custom one.

It may also install a new toolbar or a browser add-on. But most notably, the hijacker will begin to generate streams of popups, banners, in-text links and various other ads directly in your browser. This, in turn, can heavily interfere with one’s day-to-day browsing activities, especially the page redirects that are a very common symptom of infections like “Browser is infected”.

There’s nothing to worry about, though, as once you have “Browser is infected” removed from your computer, all of this advertising nonsense will cease. And below we have included a detailed removal guide that will walk you through the process.

Basically, the developers of “Browser is infected” for Mac profit from all the many popups and banners that are displayed on the affected user’s screen.This is made possible thanks to popular online business models such as Pay Per Click. And that is why the advertising practices are generally as aggressive as they are. The hijacker in question pretty much aims to place the ads in such an inconvenient way for the targeted user that they are virtually forced to click on these ads in order to be able to get on with their web browsing.

What is “Browser is infected”?

If you’re worried whether “Browser is infected” is some type of virus or malware, don’t be. “Browser is infected” is not a malicious program and it will not damage your computer the way that actual malware can. Nevertheless, experts are still wary of these types of programs and have dubbed them potentially unwanted. This is, in part, due to the fact that there’s a risk of being exposed to malicious programs from all the page redirects and constant display of advertising content. Thus, to avoid running into ransomware, Trojans or other nasty threats, we recommend trying to avoid clicking about on ads and simply just seeing to the removal of their source.
