Remove the Fake BitDefender 2011 (Uninstall Guide)

Tell your friends:
BitDefender 2011 is a rogue anti-virus program that demands money to clean up non-existent infections in your computer. I think you all know the legitimate anti-virus software from BitDefender which is a well known company and obviously has nothing to do with the BitDefender 2011 scareware. It's an old but effective trick and I'm afraid that may fool casual users into installing this rogue anti-virus application. Previously, we wrote about the fake E-Set Antivirus 2011 and AVG Antivirus 2011; these are pretty much the same as BitDefender2011. Just like most other scareware, BitDefender 2011 is promoted through the use of Trojan horses and infected websites that redirect you to fake online virus scanners. Fake AV scanner reports tons of infections on your computer and prompts to install fake virus protection software. Once BitDefender 2011 is installed, it pretends to scan your computer for viruses, spyware, adware and reports even more non-existent threats. It is worth noting, that this rogue anti-virus software can not delete your files, so you shouldn't worry about that. If you have the fake BitDefender 2011 on your computer and need help removing it, please follow the removal instructions below.



While BitDefender 2011 is running, it displays fake security alerts in attempt to scare you into thinking that your computer is fried. For those of you who have already been hit by rogue anti-spyware software these fake alerts shouldn't be a surprise. Bit Defender 2011 displays some pretty basic stuff. The fake alert will state that your computer is infected with spyware, keyloggers and other badware. You may also see a fake security warning saying that you are using unlicensed software or that your sensitive information is being transferred to a remote server which belongs to cyber-criminals. Such offending warnings should be ignored as they do not make any sense. Here are some of the fake security alerts:



Another rather annoying thing about this infection is that BitDefender 2011 blocks legitimate malware removal tools. However, BitDefender 2011 Resident Shield blocks other legitimate programs too, i.e., Microsoft calculator or registry editor. It states that the program is infected and was terminated due to security reasons. Surprisingly, it doesn't block Task Manager, but there is a good reason for that. BitDefender 2011 created a new column in the Windows Task Manager that displays word "Infected" next to various active processes.

And probably last, but not least, BitDefender 2011 hijacks web browsers via the Image File Execution Options and displays fake security warnings Internet Explorer Emergency Mode (Internet Explorer) and Attention! Your web page requested has been canceled (Mozilla Firefox).





These fake alerts do not show up in safe mode and safe mode with networking though. So, you should restart your computer is safe mode with networking and download anti-malware application to remove the rogue AV if it blocks security-related websites in normal mode. Also, you can use the registration codes listed below to activate the fake BitDefender 2011 if you really can't do anything on your computer. Thanks to Steven K. from http://xylibox.blogspot.com for sharing these codes. Just click "License" from the left side menu and enter one of these codes:

DLE01-JGN91-KAH52-DPH063-XYL52
IGE19-CJA07-FDK41-CMI651-XYL62

PFI91-ENK07-KLC65-MCJ224-XYL81
JGA43-KGJ19-DHG29-MOM599-XYL52
DAO35-KGB74-CHC40-FLI616-XYL14
ENK13-PFD81-OFH29-HMF191-XYL63

Please note that even if these codes will do the trick, you still need to run a full system scan with anti-malware software. Do not purchase BitDefender 2011. There is no guarantee that your credit card details aren't going to be sold to other third parties. Clarifications and comments are welcome as usual.
