The purpose of the antivirus module is to ensure detection
and removal of all viruses in the wild. BitDefender Antivirus uses
robust scan engines certified by ICSA Labs, Virus Bulletin,
Checkmark, CheckVir and TÃœV. The firewall module filters
network traffic and controls the access permission of applications
connecting to the Internet. In Stealth Mode, your computer is
“hidden” from malicious software and hackers. The firewall module
is capable of automatically detecting and protecting against port
scans (streams of packets sent to a machine in order to find
“access points”, often in preparation for an attack).
