Bitdefender replaced SOFTWIN's earlier AVX  (AntiVirus eXpert) product range. Between 1996 and 2001 AVX became a product available worldwide that offered intelligent updating without user intervention and integrated an internal browser which scanned and monitored all downloaded files. AVX pioneered behavior-based application blocking technology and was also the first antivirus product to include personal firewall features. With the sixth generation of AVX, the product became the first antivirus package to include an application firewall as well as behavior-based blocking. The Bitdefender group spun off from SOFTWIN in 2007.
The Bitdefender range includes antivirus products for home users and businesses. Home editions support Microsoft Windows, Symbian OS, Windows Mobile, Mac OS X, Android and iOS ; 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 control components. 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 Antispam NeuNet
Bitdefender Antispam NeuNet, 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 2006 Bitdefender introduced a new technology, B-HAVE (now patented), 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.
it 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.
After being criticized in May 2009 as being unresponsive, support was available 24/7 on telephone, e-mail, Livechat and a knowledge base. As of July 2013 the help URL redirects to the BitDefender Support Page which includes knowledge base articles but no email, telephone or LiveChat.
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.
Comodo Firewall Incompatibility
As of version 2012 of Bitdefender, both programs cannot co-exist. There is however, a workaround which can be found elsewhere on the internet and at the Bitdefender forum:
