This page aims to help you remove Antanna “Virus”. These Antanna “Virus” removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

Maybe you are now searching for some details about a kind of software, which has recently been making your browser apps produce a noticeable amount of banners, boxes, pop-ups and other ads; as well as often send you to websites you cannot recognize or have never intended to visit; or/and even show homepages and search engines that are totally different from the ones you have set. In this article we really try to give you as many details about the program, which is the root of all this irritation – Antanna “Virus”, as we possibly can.

All you need to know about Antanna “Virus” and the software category it belongs to:

The term that most accurately describes Antanna “Virus” is the “browser hijacker”. Hijackers are programs, specialized in the aforementioned activities. Also, what we should definitely mention about them is that they could affect all of the most popular browser apps – Chrome, Opera, Explorer, Firefox, etc. A few users may consider the changes such programs invoke in their browsers too annoying or even intrusive. The relatively big number of ads produced might irritate the infected users even further. Still, there is not a single reason concrete enough to place Antanna “Virus” into any malware subtype. This program isn’t related to Ransomware – it cannot encrypt any data and make it inaccessible to the affected user. What’s more, its actions cannot define it as a Trojan horse virus, as Antanna “Virus” cannot use any system and/or program vulnerability for the purpose of invading your system. In conclusion, there is nothing really malicious about browser hijackers. However, they might have some pretty suspicious potential effects. One of them is their ability to track your most recent search requests using your browser’s history records, and authorize only the appearance of ads, which promote a service, a product or something that you have recently shown some interest in. Moreover, Antanna “Virus” may relate its rather negative reputation to the redirections it could cause. It has been implied that this sort of sudden redirecting might actually lead to web pages, full of malware.

One more potential reason for concern could be the way browser hijackers normally access and infect your PC. Indeed, there could be a lot of potential sources – spam, emails, documents, redirecting hyperlinks, contaminated web pages and torrent and/or shareware spreading websites. Still, the most commonly used one remains the so-called process of software bundling. This practice is very popular among programmers, through which they mix various types of software like Adware, original programs, or hijacker programs such as Antanna “Virus” and distribute them as a package. It is totally legal; the developers in fact get paid for spreading ad-related products. In fact, this is a really common business model that is based on the remuneration system called pay per click – the more  ads get clicked by users, the more money the developers make based on those clicks.

When talking about the way your system may catch an Antanna “Virus”- caused infection technically, we have to point out the fact that many users still believe that any hijacker is capable of self-infecting your browser apps. Nevertheless, this is NOT true at all. You might end up catching Antanna “Virus” only in case you, yourself, authorize it to be installed on your PC, which could occur with your knowing or unknowing approval. Normally, many users are so eager to use a piece of software from one of the aforementioned bundles that they may want it installed as soon as they have downloaded the bundle. This is usually their main mistake, as installing any program by one of the QUICK / BRIEF /or AUTOMATIC functions will more often than not allow all the programs inside the bundle to enter your system. The only proper way of integrating any software into your system is via the CUSTOMIZED/ CUSTOM OR ADVANCED installer features.
