Applications include web protection, cloud antispam, firewall, vulnerability scanner, parental controls, file encryption, device antitheft and backup for corporate and home users.

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 products[edit]

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.[3] A free basic online scan[4] 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. Now they offer real-time protection.[5] Bitdefender competes in the antivirus industry against Avira, BullGuard, F-Secure, FRISK, Kaspersky, McAfee, Panda Security, Sophos, Symantec and Trend Micro among others.


TrafficLight Logo

TrafficLight is a browser add-on that features an advanced malware filter, phishing attacks prevention, tracker identifier, and a link scanner. It gives a signal before the link for the users to know if the page is clean, unscanned, or malicious. It is also bundled with Bitdefender Antivirus products.

Safego online[edit]

Safego logo

Safego is an application designed to protect online social community members from different types of e-threats and spam.[6] The application was originally released on Facebook,[7] and a Twitter version of Safego was then released (2011).[8] After installation, BitDefender safego scans the content posted on the user's Facebook wall and news feed.[9] Users are warned in case a message in their news feed, on their wall, or in their inbox contains links to malware, or is considered to be spam by the BitDefender scanning engines. Safego was closed on July 2013.

Safego includes a privacy protection feature which warns users in the event their public profile contains private data that can be accessed freely by persons who are not among their contacts.[10] BitDefender safego uses the BitDefender anti-malware and anti-phishing engines to scan URLs in the cloud. This scanning process is based on a blacklist of untrusted web sites and on heuristic detection.

Bitdefender technologies[edit]

Bitdefender Antispam NeuNet[edit]

Bitdefender Antispam NeuNet,[14] 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[15] 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.[16]

Active Virus Control[edit]

Incorporated in the 2010 product suites, Bitdefender introduced another technology, 'Active Virus Control,' in August 2009.[17]

It continuously monitors each program[18] (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 a third layer of defense.

PHOTON Technology[edit]

In its 2014 version, Bitdefender now features the "PHOTON Technology" which makes it possible for Bitdefender to visibly improve computer speed and performance by gradually adapting to each PC.

Independent tests[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.[19] As of June 2007, Bitdefender had passed Virus Bulletin's VB100 independent tests 14 times out of 18 since first tested in 2002.[20] It also achieved an advanced certification from AV Comparatives for on-demand scanning,[21] and standard level certification for catching unknown viruses, though it was criticised for its slower scanning speed and higher instances of false positives.[22] 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.[23]

In another test conducted by AV Comparatives in August 2009[24] 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".[25] It is also the least expensive of the top three antivirus solutions, as ranked by PC World.[26] 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."[27]



After being criticized in May 2009[28] as being unresponsive, support was available 24/7 on telephone, e-mail, Livechat and a knowledge base.[29] 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.[30] Bitdefender representatives announced the removal of the faulty update and a workaround for the users affected,[31] except for those using the 2008 version.[32]

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 at the Bitdefender forum:[33]

ASUS AiSuite incompatibility[edit]

Bitdefender is incompatibile 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" [34]
