BitDefender Antivirus 2012 is a thorough antivirus scanner for Macs which protects both your hard drive and network in real time.
BitDefender Antivirus 2012 for Mac protects against viruses, worms and trojans and includes an anti-phishing module which is capable of integrating with Safari and Firefox as a plug-in. The interface is generally clean with all the main options clearly displayed. There's also an extensive settings and configuration tab for those that need to tweak it.
BitDefender Antivirus 2012 protects in real time and doesn't hog your system resources like some Mac antivirus apps do. Although manual scans are possible, they are a little slow, so bear in mind that you may have to wait a while for them to complete. You can blacklist certain folders to speed-up scans though and for those files that are infected, BitDefender Antivirus 2012 allows you to disinfect or delete them.
