Antivir is a collection of a few different pieces of malware, the heart of which is a rogue anti-virus application. This rogue security software should not be confused with Avira Antivir, which is a legitimate anti-virus product. The con-artists who created the Antivir rogue security program took a portion of the name of Avira's product, because they knew it would fool people. The rogue Antivir first appeared in November 2009, and since then, it has spawned a multitude of clones, descendants, and offshoots. Ultimately, the goal of Antivir is to scam you out of your money, and no matter what Antivir may tell you about your system’s security, you should not believe it. Above all, do not download or pay for Antivir, in any form.

Antivir Can Infect a Computer with Different Kinds of Infection

Antivir can occur at a few different levels of complexity, because Antivir encompasses adware and a rogue anti-virus program, both of which may use a hijacker, and which do not necessarily infect things at the same time. For example, your computer can have an infection of just the Antivir adware, in which case you will get a bunch of pop-ups advertising this bogus software, without other symptoms. Alternatively, your computer can be infected with the full rogue anti-virus application, which focuses on scaring you into thinking that your system is plagued by viruses, but which may also generate pop-ups to promote itself. In either case, Antivir can use a hijacker to change your Internet Explorer settings and redirect you to its own sites when you attempt to go online, telling you that whatever other sites you try to visit have been blocked because they are unsafe. Also, either way, Antivir will eat up a bunch of system resources and leave your computer running unusually slowly.

Most of the time, Antivir relies on Trojans in order to get a foot in the door and set off an infection. The Trojans are typically hidden in things that you download or access online that seem harmless, like updates to plugins, or video codecs. Then the Trojan that infects the system will download Antivir or activate the adware. In the case of an infection with the Antivir adware, the ads will direct you to a site that claims to be selling an Antivir security program, in order to trick you into downloading the Antivir rogue yourself. You might also be tricked into downloading the rogue by following an ad to a free system "scan", which actually infects the system with Antivir. One of the vitally important things to the creators of Antivir, the scam artists who profit from this fraud, is that you become convinced that Antivir is real security software. These fake sites and phony free scans are one way of trying to get you to believe what they want you to.

Antivir also is structured to look as if it is a Microsoft product, or as if it has some connection to Windows, in order to be effective in scaring you into paying for the software. When the Antivir rogue anti-virus application infects a system, it will set itself up to run as soon as Windows starts. When it runs, it will display a fake home screen that uses the shield logo for Windows Security Center and is structured to look realistic. This home screen will run bogus scans of your computer and tell you that it has found a bunch of dangerous viruses, and then it will alert you that the only way to remove these "threats" completely is to buy a full or licensed version of Antivir. However, all the threats are fake; Antivir is the only threat, and there is no licensed or real version to be had. No matter what it may say or how good it may look, Antivir lacks the ability to scan for or remove anything. This also goes for all of its phony pop-up warnings that it can create, warning you about urgent security issues – it cannot detect threats, and all of the warnings are just there to scare you.

The True Meaning of Antivir

So when you get down to it, Antivir is a scam – created by some people in Russia – which tries to prey on your fear of viruses and information theft. Antivir, in its original formulation that appeared in late 2009, is incapable of anything else, good or bad. Don’t let yourself be manipulated by this fraud You can get Antivir off of your computer, and you do not have to pay money to its con-artist creators.
