BitDefender Total Security 2012
Bitdefender is an antivirus software suite developed by Romania-based software company Softwin. It was launched in November 2001, and is currently in its 15 build version. The 2011 version was launched in August 2010, and it includes several protection and performance enhancements as Search Advisor and Performance Optimizer. The 2012 version was launched in 27 July 2011.
The BitDefender products feature antivirus and antispyware, personal firewall, privacy control, user control and backup for corporate and home users. PC Tuneup and Performance Optimizer are available in the Total Security Suite.
The Bitdefender range includes antivirus products for home users and businesses. Home editions support Microsoft Windows, Symbian OS,Windows Mobile and Mac OS X; business editions support Microsoft Windows, Linux, FreeBSD, Solaris and Mac OS X. The current version of the Home/Home Office security suite includes antivirus, anti-spyware, firewall, e-mail spam filtering, backup, tune-up and parental controlcomponents A free basic online scan is offered via the Bitdefender website. The Free version however does require free registration and is valid for 1 year after registration.
Bitdefender is designed to protect computers from viruses and spyware. Unlike the commercial version, the free tools only offer an on-demand virus scanning and doesn't provide real time scanning, and may therefore be less suitable for machines with a continuous connection to the internet.
Bitdefender Antispam NeuNet
Bitdefender Antispam Neu Net, short for Neural Network is an antispam filter pre-trained by the BitDefender Antispam Lab on a series of spam messages, so that it learns to recognize new spam by perceiving its similarities with the messages it has already examined.
In May 2005 BitDefender introduced a new technology, B-HAVE (patent pending), to reduce dependency on virus signatures through proactive detection of unknown threats. This technology is based on behavioral analysis in a virtualized environment.
To determine whether a program is malicious or not, this technology makes use of a virtual PC in which files are executed and analyzed. The virtual PC includes a set of virtual hardware devices, mimicking the configuration of a typical PC. B-HAVE checks for characteristics known to be associated with malware. A program may be deemed to be malicious if it attempts to modify certain files, read from or write to a sensitive area of the memory or create a file that is a product of a known virus. When attempting to use an un-trusted program, B-HAVE delays the launching until the program’s behavior and characteristics are analyzed and catalogued in the virtual environment. If no malicious actions are detected, B-HAVE starts the program normally; if a suspect conduct is present, B-HAVE automatically quarantines or deletes the application.
Active Virus Control
Incorporated in the 2010 product suites, Bitdefender introduced another technology, Active Virus Control, in August 2009.
Active Virus Control continuously monitors each program (specific processes) running on the PC, as it executes, and it notes any malware-like actions. Each of these actions is scored and when a given threshold is reached, the process is reported as harmful. Unlike heuristic technologies that check executable files when they are accessed or first started, Active Virus Control monitors everything applications do as long as they are active. Because of this approach, Active Virus Control is considered a third layer of defense.
In reviews for Bitdefender, the home version of the suite was given the PC Answers editor's choice award in a comparative review in May 2007. As of June 2007, Bitdefender had passed Virus Bulletin's VB100 independent tests 14 times out of 18 since first tested in 2002.It also achieved an advanced certification from AV Comparatives for on-demand scanning, and standard level certification for catching unknown viruses, though it was criticised for its slower scanning speed and higher instances of false positives. The performance of Bitdefender's heuristic antivirus technology was measured using the detection rate of new and unknown viruses in a test conducted by Anti Malware Test. In another test conducted by AV Comparatives in August 2009 to determine the antivirus software with high detection rates and the lowest false positives rating, Bitdefender received an Advanced+ Certification. In a test conducted by PCMag, Bitdefender 2010 , "detected 97 percent of all the threats and completely blocked installation for most of them". It is also the least expensive of the top three antivirus solutions, as ranked by PC World.

Although being criticized in May 2009 as being unresponsive, support is available 24/7 on telephone, e-mail, Livechat and a knowledge base.
On March 20, 2010, computers running Bitdefender under 64 bit versions of Windows were affected by a malfunctioning update which classified every executable program as well as dll files as infected. These files were all marked as 'Trojan.FakeAlert.5' and were moved into quarantine. This action led to software and systems malfunctions that affected users around the world.
BitDefender representatives announced the removal of the faulty update and a workaround for the users affected, except for those using the 2008 version.
