FWIW, there is no such checkbox in my copy of 10.8.3

AV for the Mac, as noted by the replies, is probably not needed. Having
said that, though, I do use the free
Avast<http://www.avast.com/free-antivirus-mac?utm_expid=70955199-4&utm_referrer=http%3A%2F%2Fwww.google.com%2Furl%3Fsa%3Dt%26rct%3Dj%26q%3D%26esrc%3Ds%26source%3Dweb%26cd%3D2%26ved%3D0CGEQjBAwAQ%26url%3Dhttp%253A%252F%252Fwww.avast.com%252Ffree-antivirus-mac%26ei%3DU01nUf2aKcGe2AXuoYDgBA%26usg%3DAFQjCNGFuQLBfk6PnEcDzSevyJLtbFQeOA%26sig2%3D75gMHEp15QTF5Y5-ImOB5Q%26bvm%3Dbv.45107431%2Cd.b2I>AV
on my Macs. Why? It's free, never gets in the way or consume major
memory, and may actually help me some day. There's no downside to using
Avast, to my way of thinking, and may possibly have an upside. You might
give it a try. It has ranked well in the various tests made on AV
programs....Jim

This question comes up constantly.

Every new Mac user immediately asks about anti-virus software (AV software) for the Macintosh. You more than likely don't need any. That's *why* many people switch to the Mac! The overwhelming majority of Mac users do completely without any AV software of any kind. You never hear of entire Mac-using offices being wiped out by a new malicious virus that spreads like crazy like you do Windows-based offices.

Here is an excellent up to date Web site on the topic of Macintosh malware
that you might find illuminating:
http://www.reedcorner.net/guides/macvirus/

...and an associated Macintosh Malware Catalog
http://www.reedcorner.net/guides/macvirus/malware_catalog.php

You will note that, in the list of malware for the Mac, above, there are no actual "viruses" (malware that is self-replicating) in the wild that can currently infect OS X and cause any damage, and there are only a couple of threats that make it as high as achieving a "Low" risk rating. Those "low" risks are handled by anti-malware software that is included in OS X:
http://www.macworld.com/article/142457/2009/08/snowleopard_malware.html
For now, all that you have to do to keep your Mac safe is keep your Mac updated with all of the Security Updates that Apple pushes to you via Software Update.

Until there is a serious threat to the Macintosh, using anti-virus software is likely to be more problematic on your Macintosh than any malware you might come across. This article is dated, but still relevant:
Mac OS X anti-virus software: More trouble than it's worth?
http://reviews.cnet.com/8301-13727_7-10331147-263.html

Your best defense for now is to keep a good versioned backup of your data.

Note that if you use Microsoft Word or Excel, there are macro viruses that are cross-platform. They can't run in Office 2008 applications, but they can run in Office 2011 applications. You can easily protect yourself from then by turning on "Macro Virus Protection" in these applications. More info:
http://kb.iu.edu/data/agzk.html

If you decide that you want to have anti-virus software after reading the above, you might like:

ClamXav (free)
http://www.markallan.co.uk/clamXav/index.php
ClamXav doesn't exactly do interactive scans, but that's probably a good thing, as it doesn't cause the slowdowns or software conflicts sometimes associated with stay-resident AV software.

There are lots of pedantic sub-topics that go along with any discussion of the need for AV software for the Mac. e.g. Do you need AV software to protect Windows users (the Typhoid Mac argument); Is the amount of malware for the Mac so low because there are so few Macs in existence; Will there be a bunch of malware for the Mac "real soon now", just like for Windows; Is the Macintosh intrinsically more resistant to malware than Windows; etc. Personally I don't think that you need to worry about any of this stuff. It is mostly just what we call FUD ("fear, uncertainty, and doubt") spread by Windows apologists desperately trying to convince you (and maybe themselves) that Windows is just as good as a Mac. I'll address any of these topics if you feel that you really need an answer (maybe to deal with a colleague or partner who is anti-Mac).

Yes, it will increase your Web surfing speed, but given the little that you have told us, I don't think that it is the source of your slowdown.

I'll give you a list of things to do that I suspect will almost certainly drastically speed up your Web speed. I'm sorry if these are too technical, but I don't know how to dumb them down.

Here are three tips that are fairly easy to implement, but which potentially could make a huge difference.

You might want to try changing these settings to see if they make a difference in your Web browsing speed. (Actually, all of these often make a significant positive difference for just about everyone.)

1) Try turning off IPv6.

Copy and paste this into Terminal and then hit Return:
networksetup -setv6off Ethernet

This will turn off IPv6.

The reason that turning IPv6 off may improve performance is that some DNS servers do not properly respond to IPv6 requests. As a result, your computer has to time out waiting for a response and then try a secondary DNS server.

In recent versions of OS X, IPv6 typically is on (set to "automatic&quot;) by default, but not used. You have nothing to lose by turning IPv6 to "off" and then seeing if performance improves. When I first turned it off, I tested it out by going to a Web site that I visit often that is typically slower to load than any other Web site that I have visited. It came up instantaneously, as if it had been cached! I had never seen it do that previously.

Changing your IPv6 setting isn't immutable. If you don't realize a performance improvement, just change it back to "automatic."

If you want to turn IPv6 back on, copy and paste this into Terminal and then hit Return:
networksetup -setv6automatic Ethernet

2) Find the fastest domain name server (DNS).

Quit all browsers.
Go into:
System Preferences --> Network --> Built-in Ethernet
and write down the numbers for the domain name server(s) (DNS) to save them.

You can find the domain name server(s) that provide the best performance for your Mac using:

NameBench (free)
http://code.google.com/p/namebench/
Just a warning, it doesn't work properly under Mountain Lion. The fix is mentioned in this page:
https://code.google.com/p/namebench/issues/detail?id=219

You have to control-click namebench.app, then click on "show package contents." Then, drill down to the location specified in line 17 (Resources/libnamebench/health_checks.py). Open health_checks.py in text edit. Hit Command-F to open the find window. Search for "hostname." You should then see the line specified in line 17. Change the "2**32" to "2**16".

Now when you run namebench, it should complete.

NameBench will take about 5 minutes to run. Be patient. Use the fastest DNS it finds to replace the existing setting in Network in System Preferences.

You can expect a significant Web browsing performance increase after using the fastest domain name server suggested by NameBench!

Note: Every time you run NameBench, it is likely to give you a different result. This is normal. Don't become manic about running NameBench. Run it during the time of day that you do most of your Web surfing. Use that result. If your Web browsing subsequently slows down noticeably at any point, you can run it again.

I would strongly recommend that you NOT use your ISPs DNS servers.

3) Clear all Flash cookies and make sure that they can't return.

Your Mac's browser downloads and maintains a type of surreptitious cookie that can't be cleared using the features in your browsers themselves. These are Flash cookies, and they are mostly used to do things that you don't want them to, like track you.
http://www.wired.com/business/2009/08/you-deleted-your-cookies-think-again/
When these cookies accumulate, they tend to slow down your browser.

Delete everything in these two folders:

- In the Finder
Option-click the Go menu
Your ~/Library will appear in the menu; choose it
Trash all of the files in the enclosed folder at:
/Preferences/Macromedia/Flash Player/#SharedObjects

- In the Finder
Option-click the Go menu
Your ~/Library will appear in the menu; choose it
Trash all of the files in the enclosed folder at:
/Preferences/Macromedia/Flash Player/macromedia.com/support/flashplayer/sys

After you clear both of these folders (#SharedObjects and sys), do a Get Info on each of these folders and lock them using the "Locked" checkbox (NOT the little lock icon at the bottom of the window).

After you do these three things, my guess is that your browser will be faster than you've ever seen it on any Mac before. Please let us know the results.

If you do all three things above, and your Web browsing speed doesn't improve immensely, let me know. That would be a sign that you have a problem that needs troubleshooting, and I can help you with that also.

Randy,

Is there are reason for using Terminal to switch off IPv6 instead of doing
it in System Preferences > Network? Has this been removed from Sys Prefs in
recent OS X versions?

It's still there, it's just that none of the choices is "off."

Thanks. So, another pointless and unnecessary change by Apple. In 10.5 you
can specify 'Off', as I did some time ago.

You may want to give "on" a try. At some point, it will be faster to have IPv6 turned on. For your ISP, that time may have already come.

This site:

http://test-ipv6.com/

will tell you
how things are going with your setup and IPv6.

If on the third line it reports:
"No IPv6 address detected,"
it is best to have IPv6 turned off on your Mac.
