Antivir is an application that should be a great tool for the system security

False anti-spyware Antivir

Antivir is a misleading anti-spyware application that reports false or exaggerated system security threats and infections to make you think that your computer is infected with malware. Once installed, it will simulate system scans and display a list of infections but won't let you remove those supposed infections unless you pay for a full version of the program. The report lists various infections not related to your machine and once you click the Fix Now button a purchase form appears. As you can see, the main goal of this misleading application is to trick you into purchasing the program. This is nothing more but a scam. Do not pay for it and uninstall it from your computer as soon as possible, if you noticed the intruder already added on the PC.

The program can be downloaded from various platforms that rely on advertisements, promotional material.

This rogue security tool often is included as the additional piece that cannot be removed unless you click Advanced or Custom options and control all the included programs on the list.

Antivir PUP

When installed, PUPs download the rogue application and displays fake security alerts. Those fake security alerts or notifications will state that your computer is infected, for example: “Warning! Identity theft attempt detected”. Other fake notification states:

Trojan:W32/Inject Activity Detected
Trojan:W32/Inject is a large family of malware that secretly makes changes to the Windows Registry. Variants in the family make also makes changes to other running processes.

Furthermore, Antivir may block legitimate anti-spyware software and block security-related websites. There shouldn't be any doubts about this bogus application – it must be removed upon detection.
