Antivirii 2011 is a new variant of the Antivirus Clean 2011 rogue family. This rogue is promoted through online advertisements that pretend to be online anti-malware scanners. When the advertisement is finished, it will automatically state that your computer is infected and then prompt you to download and install the Antivirii 2011 program onto your computer. Once the program is installed, it will be configured to start automatically when you login into Windows. Once running, it will pretend to scan your computer for infections and when finished will falsely state that your computer is infected with a variety of malware. If you attempt to use the program to remove any of these infections, though, it will state that before you can remove anything you first need to purchase the program. It goes without saying that you should ignore any of these scan results and not purchase the program.

As a protection method, Antivirii 2011 will also add a Windows Registry setting so that you are not able to launch the Windows Task Manager. The rogue will also display fake security alerts on the infected computer. The text
of these alerts are:
Your computer is in danger!
Antivirii 2011 has detected some serious threats to your computer!
These viruses need to be eliminated immedeately <sic>! Please click this icon to remove threats.
Your system is infected!
Your computer is compromised by hackers, adware, malware and worms!
Antivirii 2011 can remove this infection. Please click this icon to remove threats.
Just like the fake scan results, these security alerts are designed to scare you into thinking your computer is infected and should be ignored.
Without a doubt, Antivirii 2011 is a scam that was designed to scare you into thinking your computer has a security problem so that you will then purchase the program. Therefore, do not purchase Antivirii 2011 for any reason, and if you already have, please contact your credit card company and state that the program is a computer infection and a scam and that you would like to dispute the charge. To remove this infection and related malware, please follow the steps in the guide below.
