No. This is not a guide for removing the legitimate ESET NOD32 Antivirus software. There is a new scareware that goes by the name E-Set Antivirus 2011. Curiously while it uses the name of ESET, it uses an icon that is very similar to AVG icon. This fraud software uses the Windows UAC like darkening of the screen to scare the victims with various fake security warning messages. The fake alerts are frequent making the desktop unusable.

Once installed on the system E-Set Antivirus 2011 rogue, blocks execution of Task Manager and command prompt, presumably to protect itself. It does not force-close any running programs.

Scareware like E-Set Antivirus 2011 are commonly installed when users are redirected to fake online scanner pages or fake ‘video codec required’ pages distributed through out the Web by cyber criminals using blackhat SEO techniques, Spam and Malicious flash advertisements.

E-Set Antivirus 2011 Analysis

A rogue security software such as E-Set Antivirus 2011 belongs to a family of software products that call themselves as antivirus, antispyware or registry cleaners and often use deceptive or high pressure sales tactics and deliberate false positives to convince users into buying a license/subscription. They are often repackaged and renamed. They do not actually remove malware instead many of them add more malware of their own. They need to be removed immediately from your system.

E-Set Antivirus 2011 severely restricts browsing. Major browsers like Firefox, Chrome, Opera and Safari are allowed to open only in a fraudulent internet explorer emergency mode. This is done by tampering with the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options. Many Websites are blocked and a fake security alert as below is displayed with a forged URL http://microsoft.com/#blacklist

This web site refused your connection as it was reported as malicious request. This can be caused by Viruses, Trojans or Malware found on your computer.

The trojan dropper file is about 129039 bytes in size. It is detected by only 2 /43 (4.7%) of the anti-virus engines available at VirusTotal.
