Bitdefender technologies[edit]

Bitdefender Antispam NeuNet[edit]

Bitdefender Antispam NeuNet,[6] is an antispam filter 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 developed a new technology, B-HAVE, to reduce dependency on virus signatures through proactive detection of unknown threats. This technology is based on a behavioral analysis in a virtualized environment.[7]

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.

Photon Technology[edit]

In its 2014 version, the company claimed to feature a new technology called 'Photon Technology', which it says visibly improves computer speed and performance by gradually adapting to each PC.[8]

Content filtering technologies[edit]

Content filtering technologies 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 the creation of signatures to proactively detect never-before-seen malicious files.

Machine learning[edit]

The company claims that Bitdefender is using cloud-based machine learning to identify new malware, malicious URLs and other online threats by processing and analysing big data to obtain behavioral patterns and predict future advanced threats.


In 2015, Qihoo 360 acknowledged accusations by three antivirus testing companies of providing for their testing a version of its anti-virus equipped with a antivirus engine licensed from Bitdefender, while the consumer version used Qihoo's own QVM engine instead.[9][10] Currently,[when?] Qihoo's 360 product includes Bitdefender, Avira and Qihoo-developed engine.[11]




On 20 March 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.[12] Bitdefender representatives announced the removal of the faulty update and a workaround for the users affected,[13] except for those using the 2008 version.[14]

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'.[15][better source needed]
