What is the best anti virus for a mac

any auggestions i have a file that wont delete or open it appears to be an excel the file # is 331A5000

The best anti-virus is no anti-virus. Most software of the sort can actually harm your computer. No, I haven't heard of this file, but you can tell us more info about it by right clicking (control + click) on the file, then selecting Get Info.
Once you have called up the Get Info screen, take a screenshot of it by pressing
⌘ + Shift + 4.
Then post the screenshot here.

Just a +1 for Kappy's suggestions. Antivirus software simply is not necessary for OS X. If you are interested in reading more an informative article is Viruses, Trojans, Malware - and other aspects of Internet Security.

I concur with Tonefox; worthless. To preserve battery the best thing you can do is shut down apps that constantly run in the background and fetch data from servers elsewhere; the Facebook app being a prime example. Apple has more tips here:

As to clearing memory, there's almost never a need, and if there is a simple restart of the iPhone will suffice.

What is the best anti~virus foe macbook pro?

None whatsoever. I'm sure that you've heard the line that "Macs don't get viruses"? That's almost true - Macs can be infected with malware, however, and can pass viruses onto PCs. See Thomas Reed's Mac Malware Guide. The only two virus packages that are usually recommended are both free - Sophos and ClamXav. If you feel that you need AV software, try one or both.
Good luck,

OS X already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
A much better question is "how should I protect my Mac":
Never install any product that claims to "speed up", "clean up", "optimize", or "accelerate" your Mac. Without exception, they will do the opposite.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources. Illegally obtained software is almost certain to contain malware.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Disable Java in Safari > Preferences > Security.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

Use what Apple already provided.
There will always be threats to your information security associated with using any Internet - connected communications tool:
You can mitigate those threats by following commonsense practices
Delegating that responsibility to software is an ineffective defense
Assuming that any product will protect you from those threats is a hazardous attitude that is likely to result in neglecting point #1 above.
OS X already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
A much better question is "how should I protect my Mac":
Never install any product that claims to "clean up", "speed up", "optimize", "boost" or "accelerate" your Mac; to "wash" it, "tune" it, or to make it "shiny". Those claims are absurd.Such products are very aggressively marketed. They are all scams.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources.
Illegally obtained software is almost certain to contain malware.
"Questionable sources" include but are not limited to spontaneously appearing web pages or popups, download hosting sites such as C net dot com, Softonic dot com, Soft pedia dot com, Download dot com, Mac Update dot com, or any other site whose revenue is primarily derived from junk product advertisements.

What is the best anti virus software to use with OS X 10.8?

What is the best anti virus software to use with OS X 10.8? Norton is slowing my iMac down and I'm constantly being bombarded by blocking messages for programs I don't recognize.
Thanks

Get rid of Norton a/k/a Symantec. It is one of the worst pieces of trash you can install on a Mac.
You do not need any additional anti-virus software than is already designed into OS X to protect your Mac against malware. I assume you paid enough for your iMac and that's part of what you paid.
If you use Windows, or are concerned about harboring viruses that target Windows, or care about friends who use Windows, then get ClamXav. It's in the App Store and it is free.
Since friends don't let friends use Windows, I have no use for it.

What's the best anti-virus protection?

What's the best anti-virus protection for my imac?

If you are running an older, unsupported OS like Leopard or Tiger, then you might consider running Sophos Home (free). Since Apple is no longer providing security updates for these, it could be a good idea.
http://www.sophos.com/en-us/products/free-tools/sophos-antivirus-for-mac-home-ed ition.aspx
System requirements
Not sure if Sophos Anti-Virus will work on your Mac? These are the technical requirements:
    Mac with Intel or PowerPC processor
    256 MB of memory
    150 MB of available disk space
    Mac with OS X 10.4 (Tiger), 10.5 (Leopard), 10.6 (Snow Leopard), 10.7 (Lion) or 10.8 (Mountain Lion)
    Supports all Apple Mac hardware including iMac, MacBook, MacBook Pro and the new MacBook Air

What is the best security system for a Mac?

I am curious as to what is the best security system for a Mac. Is it Norton or something else? I have a Macbook Pro with Lion and I want to make sure I avoid all of the viruses and malware out there.

Hi c,
General consensus here is to stay far, far away from Norton, and that most anti-malware software for Mac causes more issues than they will ever avoid.
Most Mac users run bare.
I still haven't seen anything in the wild, no OS X virus really going beyond proof of concept; some malware, yes, but not a virus. And the existing malware requires users to "open the door" and basically tell the malware it's ok to do its thing. I'm not sure there'll ever be software which can overcome the actions of such a user.
For those who feel the need, ClamX has been often suggested.

What is the best DVD Creator for a Mac Book Pro to replace iDVD?

What is the Best DVD Creator for a Mac Book Pro to replace iDVD? Have Maverick OS.

I have already looked at other threads in this forum, so 'I venture forth' to ask my question here:
I have a 44 minute carefully edited iMovie with several chapter markers. I dimly recollect that when you 'dump' the entire movie into iDVD (my version is 7.1) it should detect the markers and create buttons to link to specific scenes. Well, the 'dumping' process obviously doesn't work.
How do you get iDVD to recognize the markers and ceate buttons to link?
I can create with iDVD a DVD that will play the movie in its entirety. This is not suitable for my purposes. I need access via a menu to specific scenes.
Thank you,
Klaus

Helpful Links Regarding Malware Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
See these Apple articles:
          Mac OS X Snow Leopard and malware detection
          OS X Lion- Protect your Mac from malware
          OS X Mountain Lion- Protect your Mac from malware
          About file quarantine in OS X
If you require anti-virus protection Thomas Reed recommends using Dr.Web Light from the App Store. It's free, and since it's from the App Store, it won't destabilize the system. If you prefer one of the better known commercial products, then Thomas recommends using Sophos.(Thank you to Thomas Reed for these recommendations.) If you already use Sophos, then be aware of this if you are using Mavericks: OS X Mavericks- Sophos Anti-Virus on-access scanner versions 8.0 - 9.1 may cause unexpected restarts
From user Joe Bailey comes this equally useful advice:
The facts are:
1. There is no anti-malware software that can detect 100% of the malware out there.
2. There is no anti-malware that can detect anything targeting the Mac because there
     is no Mac malware in the wild, and therefore, no "signatures" to detect.
3. The very best way to prevent the most attacks is for you as the user to be aware that
     the most successful malware attacks rely on very sophisticated social engineering
     techniques preying on human avarice, ****, and fear.
4. Internet popups saying the FBI, NSA, Microsoft, your ISP has detected malware on
    your computer is intended to entice you to install their malware thinking it is a
    protection against malware.
5. Some of the anti-malware products on the market are worse than the malware
    from which they purport to protect you.
6. Be cautious where you go on the internet.
7. Only download anything from sites you know are safe.
8. Avoid links you receive in email, always be suspicious even if you get something
    you think is from a friend, but you were not expecting.
9. If there is any question in your mind, then assume it is malware.
