There are no mac viruses and if there were, no
hello
It isn't.
Not unless you are running Windows on your Mac. You do not need anti-virus software on your Mac slowing it down. There has never been a real world virus infect the Mac OSx. There have been a handful of malwares infect a Mac but if you are safe and smart they will not infect your Mac. Been using an iMac for 4 years without one infection and I run no security software.
You can download a free antivirus for a PC such as AVG, Microsoft Security Essentials or Comodo Internet Security. If you have a mac Sophos Anti-virus, Comodo AntiVirus for Mac and PC Tools iAntiVirus.
There are no viruses infecting Mac OS X.
Bacteriophage is the virus that infects bacteria

DNS is not a virus. DNS stands for Domain Name Servers or a way how your PC will connect to the web. This virus the FBI Terminated was called DNSChanger. Macs were hard to edit as always'
There are no viruses that infect Mac OS X so it is impossible to detect a virus. You can use ClamXAV to check if there are Windows viruses that you may be passing onto people using a computer with the Windows operating system. If your Mac software is up to date it will inform you if you have managed to download and install some form of Malware on your Mac.
Conficker only affects Microsoft's Windows operating system and so will not infect a Mac running Mac OS X.
LOTS ON A PC. Thousands, tens of thousands, hundreds of thousands, who knows? Symantec's anti-virus definitions download file is over 30MB! If you use a PC, you need a good Firewall and security software. NONE ON A MAC. There are no known active Mac viruses, though they are theoretically possible. Macro and e-mail viruses can be transmitted by Mac programs but to date will not affect the Mac itself. The built in Mac security is adequate for most users.
The infect your computer by being undetected by your anti virus and posing as a harmless file.
