Bitdefender replaced SOFTWIN's earlier AVX[2] (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.

Bitdefender technologies[edit]

Bitdefender Antispam NeuNet[edit]

Bitdefender Antispam NeuNet,[7] 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, 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 a non-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.[8]

Active Virus Control[edit]

Bitdefender introduced Active Virus Control in August 2009.

This technology continuously monitors each program (specific processes) running on the PC as it executes, and it notes any malware-like actions. Each action 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 started, Active Virus Control monitors everything applications do as long as they are active. Because of this approach, Active Virus Control is a third layer of defense.

PHOTON Technology[edit]

In its 2014 version, Bitdefender featured the "PHOTON Technology", which visibly improves computer speed and performance by gradually adapting to each PC.

Content filtering technologies[edit]

They have been developed to filter raw online content and are applicable and used in antispam, anti-phishing, web filtering, scanning of spam and social networks. They facilitate creation of signatures to proactively detect never-before-seen malicious files.

Machine Learning[edit]

Bitdefender uses cloud-based Machine Learning to identify new malware, malicious URLs and other online threats by processing and analyzing big data to obtain behavioral patterns and predict future advanced threats.

Independent tests[edit]

As of June 2007, Bitdefender had passed Virus Bulletin's VB100 independent tests 14 times out of 18 since first tested in 2002,[9] including the 12 most recent tests.[10] It also achieved an advanced certification from AV Comparatives for on-demand scanning,[11] and standard level certification for catching unknown viruses, though it was criticised for its slower scanning speed and higher instances of false positives.[12]

In another test conducted by AV Comparatives in August 2009[13] 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".[14]

Product reviews[edit]

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.[15] It is also the least expensive of the top three antivirus solutions, as ranked by PC World. TopTenREVIEWS gave Bitdefender Antivirus Plus a 9.8 rating out of 10, and said "Bitdefender combines superb protection, ample features, and comprehensive support at a price that’s lower than other high-ranked programs."[16]



After being criticized in May 2009[17] as being unresponsive, support was available 24/7 on telephone, e-mail, Livechat and a knowledge base.[18] As of July 2013 the help URL redirects to the BitDefender Support Page, which includes knowledge base articles and also 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.[19] Bitdefender representatives announced the removal of the faulty update and a workaround for the users affected,[20] except for those using the 2008 version.[21]

Comodo firewall incompatibility[edit]

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 on the Bitdefender forums.[22]

ASUS AiSuite incompatibility[edit]

Bitdefender is incompatible with ASUS AiSuite2 and ASUS AiSuite3, a motherboard optimization suite of software bundled with ASUS motherboards which enables automatic overclocking, power tuning and fan control. Bitdefender claims that the incompatibility is due to "NDIS ASUS driver (WinpkFilter LightWeight Filter), which prevents the installation of some Bitdefender files".[23]
