The Sigonews Virus is categorized by the website redirects and pop-up ads

There is no doubt that getting constantly redirected to random unknown pages and having obstructive ads getting displayed on your screen while browsing the Internet can be a rather frustrating experience especially for those users who need to use their browsers in a regular basis. And let’s be honest – who doesn’t need to open their browser pretty much every time they turn on their PC? This makes the online ads that tend to aggressively flood the users’ screens one of the most commonly-encountered and one of the most unpleasant software issues that people tend to face. There are, however, two different causes behind such an issue. The first cause are the sites you visit and the second is browsing components for Chrome, Firefox (and other browsers) that change the search engine, the homepage, the new-tab page and the toolbar of the browser that you use and, through those changes, try to stream advertising materials to your screen that would pop-up in your browser regardless of what site you are on at the given moment. In this post, we will be focusing on those so-called browser hijacker apps since their ads and page-redirects are far more annoying than the ones you could experience from visiting a website that has overly-aggressive ads embedded within its pages.

A typical example of a potentially unwanted program is the Segurazo Antivirus.

The Sigonews Virus

Sigonews is known to be a browser hijacker. Numerous complaints about Sigonews include webpage redirects, unwanted advertisements and unapproved changes to the user’s browser.

Sigonews is a relatively new piece of software and a lot of users might actually think of it as some sort of useful browser add-on application that can help them surf the Internet in a safer and in more optimized way. Nevertheless, the security specialists have flagged this software component as a browser hijacker due to some of its less pleasant traits such as its ability to spam you with pesky ads, nagging page redirects and also to impose potentially unwanted changes on the user’s browser without first asking for a permission from the computer Admin. Those are all traits typical for a representative of the browser hijacker category which is why this software component is categorized as a hijacker.

Sigonews on Android

Researchers have labeled Sigonews a browser hijacker. Security problems such as Sigonews are known to cause website redirects, intrusive advertisements and even phishing attempts.

.As we said already, browser hijackers are not the most desirable software pieces you could get on your computer due to a number of reasons. The first and most obvious one is their sheer ability to irritate you with their nagging ads and other advertising materials such as banners, pop-ups, blinking messages and so on. Some of them even tend to redirect you to pages you likely don’t want to visit. However, this isn’t the only reason why such software apps are unwelcome on most computers. Another issue with hijacker apps the likes of Sigonews is that they aren’t the safest type of software out there. Here, we don’t mean to scare you so don’t think that a hijacker is as dangerous as a virus program of the Trojan Horse or of the Ransomware category – that’s certainly not the case. However, a browser component like Sigonews could still make your machine less safe mainly through its adverts. Not all of the advertising materials and of the pages you might get redirected to due to the hijacker’s activity can be verified as safe and secure. It’s perfectly possible that some shady and hazardous advert manages to get inside the stream of ads that Sigonews directs at your screen and if you accidentally click on such an ad, you might put your computer at risk of getting infected with all sorts of threatening malware programs (Rootkits, Trojans, Spyware, Worms and, of course, Ransomware).

The Sigonews Spam

Sigonews is regarded as a type of a browser hijacker. Threats like Sigonews are known to cause different problems like changing of the user’s designated home page or even the preferred browser of choice.

The best piece of advice we could give you here is to be vigilant and responsible on the Internet. Never download anything that comes from shady sources, unknown and obscure developers or that might be pirated. Also, it’s generally advisable that you stay away from sites and pages that look fishy and that might be illegal as those could also land you some pesky software piece like Sigonews or even some more dangerous program. Installing new software on your PC must also be done with care and attention to detail. Do not simply use the Default setup configuration and instead go to the Custom setup menu and see if there aren’t any added bonus components bundled with the installer which you might not want to have on your computer. Anything suspicious and potentially unwelcome should be unchecked before you go on to launch the main installation process!
