Which antivirus software is the best for Mac?
The problem with anti-virus software is that it slows down your computer. There are 115,000 Windows viruses, there is one malware for MacosX which requires you to go to a porn site to get it. I get an occasional virus for Windows sent to me via email, I just trash it. Let the Windows users have their anti-virus software. If you still want one, then get the Intego version. The package includes Mac and Windows versions so you can protect the Windows side of your Mac if you are also running Windows on it.
