Bitdefender is an antivirus software suite developed by Romania-based software company Softwin. 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.
