No, there is no immunity of mac but because the File system is different Mac OS X has HFS & XP uses Fat 32 or NTFS. It is very hard to get your Mac sick from your Boot Camp Partition/Drive more so if you use NTFS. I would not use ClamXav on Leopard or any OS X it has a flaw http://www.frsirt.com/english/advisories/2006/1807
I would use in this order Internet Security Barrier X5 that has Intego VirusBarrier X5 10.5.3 with in it, Norton 11 for Mac, ProtectMac AntiVirus 0.9.3 & then iAntiVirus Free Edition, the reason I put iAntiVirus is it is the only Mac Only Antivirus softwhere I listed but it is fast & free. If you have not opened Norton buy Intego VirusBarrier X5 it is way faster & now comes with BitDefender AV a much better AV then Norton (PC Answers editor's choice award in a comparative review in May 2007.) I got my links from CNet Downloads or the brand sight.

Here is just some of the info on ClamXav
Hope I was of help,

Do i need antivirus with leopard?
Hi guys i am new to mac. Do i need antivirus for leopard? If so where i can i get a free one? Thanks. Mac's are the best.
Do You Need Anti-Virus Protection for Your Mac?
According to Rich Mogull's article, Should Mac Users Run Antivirus Software?,
"The reality is that today the Mac platform is relatively safe. There are hundreds of thousands of viruses and other malicious software programs floating around for Windows, but less than 200 are known to target the Mac, and many of those are aimed at versions of the Mac OS prior to Mac OS X (and thus have no effect on a modern Mac).
It's not that Mac OS X is inherently more secure against viruses than current versions of Windows (although it was clearly more secure than Windows prior to XP SP2); the numerous vulnerabilities reported and patched in recent years are just as exploitable as their Windows equivalents. But most security experts agree that malicious software these days is driven by financial incentives, and it's far more profitable to target the most dominant platform."
Mr. Mogull is a computer security expert. I recommend reading the entire article as it is quite informative.
For additional information on viruses, trojans, and spyware visit The XLab FAQs and read the FAQs on viruses and spyware.
There is only one free anti-virus software - ClamXAV. Find it at VersionTracker or MacUpdate. -
Spinning beach ball with Leopard 10.5 - mach_msg_trap - Hangs
Hi,
since I upgraded to Leopard, my Macbook Pro hangs sometimes. I recorded today such a hang (10-20 minutes, spinning beach ball) with "Spin Control".
It seam to me, that some resources are locked by the OS. Is anybody able to describe what happens?
Thanks a lot in advance

I am trying to install symantex antivirus and it says I need Rosetta from Snow Leopard. How do I get this?

You have a Retina MacBook Pro, it runs OS X 10.7 or 10.8.
It won't run Snow Leopard (10.6) and Rosetta is only for Snow Leopard to run older PowerPC processor based programs when Mac's used to have those instead of the Intel processors they all have now.
So that software your installing is incredibly old, if you bought it, return it for a refund.
Also you don't need a anti-virus for OS X, Apple installed one for all OS X 10.6.8-10.8 users.
If you need anti-virus to clean the Windows files of their malware before passing it on, then the free ClamXav does the job.

Antivirus for Mac OS X 10.6 Snow Leopard
Hi,
I am new to the mac world, Can you advice me to find out the best Antivirus software for Mac OS X 10.6 Snow Leopard
Thank YouHi, and welcome to the forums.
There are no viruses that run on OSX. None. Zip. Zero.
If you're running Windoze on your Mac, that's the same as running it on a PC, so it needs all the same anti-everything stuff you'd use on a PC.
There is some "malware," such as Trojans, for Macs, though. But (unlike viruses that can get onto your system without your knowledge), you must approve their installation (via your Admin password) and/or operation (via the "This application was downloaded from the internet ..." prompt).
Appropriately enough, some of these Trojans are included in pirated versions of Apple software, such as iWork!
For the gory details, see Thomas Reed's [Mac Virus Guide|http://www.reedcorner.net/thomas/guides/macvirus]. -
Virus? Antivirus software for Leopard?
Recently, our flawless iMac (currently running 10.5.8) that we've owned since December of '07 and that has worked perfectly has started freezing or not coming out of 'sleep'.
We've successfully rebooted and everything seems fine but once in a while it will just freeze in the middle of a screen change or something else entirely innocent.
Do you think it's a virus? Are there ANY Antivirus programs out there that we should be using?
Do we even NEED an antivirus program for this OS?
Any help will be greatly appreciated.No viruses that can attack OS X have so far been detected 'in the wild', i.e. in anything other than laboratory conditions.
Do not be tricked by 'scareware' that attempts computer users to download fake anti-virus software that may itself be malware. More on that here:
http://news.bbc.co.uk/1/hi/technology/8313678.stm
Beware of PDF files from unknown sources. A security firm announced that by its counting, malicious Reader documents made up 80% of all exploits at the end of 2009.:
http://www.computerworld.com/s/article/9157438/RoguePDFs_account_for_80_of_all_exploits_saysresearcher
It is possible, however, to pass on a Windows virus to another Windows user, for example through an email attachment. To prevent this all you need is the free anti-virus utility ClamXav, which you can download for Tiger and Leopard from:
http://www.clamxav.com/
The new version for Snow Leopard is available here:
http://www.clamxav.com/index.php?page=v2beta
(Note: ClamAV adds a new user group to your Mac. That makes it a little more difficult to remove than some apps. You’ll find an uninstaller link in ClamXav’s FAQ page online.)
However, the appearance of Trojans and other malware that can possibly infect a Mac seems to be growing, but is a completely different issue to viruses.
If you allow a Trojan to be installed, the user's DNS records can be modified, redirecting incoming internet traffic through the attacker's servers, where it can be hijacked and injected with malicious websites and pornographic advertisements. The trojan also installs a watchdog process that ensures the victim's (that's you!) DNS records stay modified on a minute-by-minute basis.
You can read more about how, for example, the OSX/DNSChanger Trojan works here:
http://www.f-secure.com/v-descs/trojanosxdnschanger.shtml
SecureMac has introduced a free Trojan Detection Tool for Mac OS X. It's available here:
http://macscan.securemac.com/
The DNSChanger Removal Tool detects and removes spyware targeting Mac OS X and allows users to check to see if the trojan has been installed on their computer; if it has, the software helps to identify and remove the offending file. After a system reboot, the users' DNS records will be repaired.
(Note that a 30 day trial version of MacScan can be downloaded free of charge from:
http://macscan.securemac.com/buy/
and this can perform a complete scan of your entire hard disk. After 30 days free trial the cost is $29.99. The full version permits you to scan selected files and folders only, as well as the entire hard disk. It will detect (and delete if you ask it to) all 'tracker cookies' that switch you to web sites you did not want to go to.)
A white paper has recently been published on the subject of Trojans by SubRosaSoft, available here:
http://www.macforensicslab.com/ProductsAndServices/index.php?mainpage=document_general_info&cPath=11&productsid=174
Also, beware of MacSweeper:
MacSweeper is malware that misleads users by exaggerating reports about spyware, adware or viruses on their computer. It is the first known "rogue" application for the Mac OS X operating system. The software was discovered by F-Secure, a Finland based computer security software company on January 17, 2008
http://en.wikipedia.org/wiki/MacSweeper
On June 23, 2008 this news reached Mac users:
http://www.theregister.co.uk/2008/06/23/mac_trojan/
More on Trojans on the Mac here:
http://www.technewsworld.com/story/63574.html?welcome=1214487119
This was published on July 25, 2008:
Attack code that exploits flaws in the net's addressing system are starting to circulate online, say security experts.
The code could be a boon to phishing gangs who redirect web users to fake bank sites and steal login details.
In light of the news net firms are being urged to apply a fix for the loop-hole before attacks by hi-tech criminals become widespread.
Net security groups say there is anecdotal evidence that small scale attacks are already happening.
Further details here: http://news.bbc.co.uk/2/hi/technology/7525206.stm
A further development was the Koobface malware that can be picked up from Facebook (already a notorious site for malware, like many other 'social networking' sites like Twitter etc), as reported here on December 9, 2008:
http://news.bbc.co.uk/newsbeat/hi/technology/newsid_7773000/7773340.stm
You can keep up to date, particularly about malware present in some downloadable pirated software, at the Securemac site:
http://www.securemac.com/
There may be other ways of guarding against Trojans, viruses and general malware affecting the Mac, and alternatives will probably appear in the future. In the meantime the advice is: be careful where you go on the web and what you download!
If you think you may have acquired a Trojan, and you know its name, you can also locate it via the Terminal:
http://theappleblog.com/2009/04/24/mac-botnet-how-to-ensure-you-are-not-part-of- the-problem/
As to the recent 'Conficker furore' affecting Intel-powered computers, MacWorld recently had this to say:
http://www.macworld.co.uk/news/index.cfm?email&NewsID=25613
Although any content that you download has the possibility of containing malicious software, practising a bit of care will generally keep you free from the consequences of anything like the DNSChanger trojan.
1. Avoid going to suspect and untrusted Web sites, especially p'orn'ography sites.
2. Check out what you are downloading. Mac OS X asks you for you administrator password to install applications for a reason! Only download media and applications from well-known and trusted Web sites. If you think you may have downloaded suspicious files, read the installer packages and make sure they are legit. If you cannot determine if the program you downloaded is infected, do a quick Internet search and see if any other users reported issues after installing a particular program.
3. Use an antivirus program like ClamXav. If you are in the habit of downloading a lot of media and other files, it may be well worth your while to run those files through an AV application.
4. Use Mac OS X's built-in Firewalls and other security features.
5. Stop using LimeWire. LimeWire (and other peer-to-peer sharing applications) are hotbeds of potential software issues waiting to happen to your Mac. Everything from changing permissions to downloading trojans and other malicious software can be acquired from using these applications. Similar risks apply to using Facebook, Twitter, YouTube and similar sites which are prone to malicious hacking: http://news.bbc.co.uk/1/hi/technology/8420233.stm
6. Resist the temptation to download pirated software. After the release of iWork '09 earlier this year, a Trojan was discovered circulating in pirated copies of Apple's productivity suite of applications (as well as pirated copies of Adobe's Photoshop CS4). Security professionals now believe that the botnet (from iServices) has become active. Although the potential damage range is projected to be minimal, an estimated 20,000 copies of the Trojan have been downloaded. SecureMac offer a simple and free tool for the removal of the iBotNet Trojan available here:

Last but not least, there is the potential for having your entire email contact list stolen for use for spamming:

Security/antivirus for MacBook (Leopard 10.5)
Hi,
Pl tell me which free antivirus is best for my macbook. I was previously using Clamxav and it detected around 50 Windows virus from pendrive but i couldnot delete the virus so i unstalled it.
Pl suggest me which antivirus to use.The pen drive includes what sort of data, and the data was transferred from a PC you own or have access to, or from a PC owned by someone else?
A Windows virus cannot affect or infect OS X, but if the data is forwarded to a Windows user who does not use antivirus or does not keep their antivirus definitions up to date, it will cause problems for such a Windows user.
Clamxav is the best free antivirus software for OS X, and I'm not aware of any other free antivirus for OS X.
If the data on the pen drive was transferred from a PC you own or have access to, run the antivirus software on that PC for the data on the pen drive. -
Some good antivirus apps either paid or free for Snow Leopard/Leopard
Any suggestions? Want to do Home Sharing too so have read some things that sometimes av apps mess with it. Dont care if the av app is paid or free. Would prefer free to start and then buy one.
Seconding Matthew's motion:
There are no viruses that run on OSX. None. Zip. Zero.
There is some "malware," such as Trojans, for Macs, though. But (unlike viruses that can get onto your system without your knowledge), you must approve their installation (via your Admin password) and/or operation (via the "This application was downloaded from the internet ..." prompt).
Appropriately enough, some of these Trojans are included in pirated versions of Apple software, such as iWork!
(If you're running Windoze on your Mac, that's the same as running it on a PC, so it needs all the same anti-everything stuff you'd use on a PC.)
For the gory details, see Thomas Reed's [Mac Virus Guide|http://www.reedcorner.net/guides/macvirus]. -
Can't open Aperture after Snow Leopard to Mavericks upgrade.
Upgraded to Mavericks from Snow Leopard. Now, the Aperture icon in the dock is greyed out. When I try to open it I get the message that I have Aperture 3.2.4 and it can't be opened with Mavericks. I purchased Aperture from the App Store when I had Snow Leopard and it shows in my purchases list, but when I check for available updates nothing shows. I have US English in my preferences, and Aperture is in my Applications file. I tried to update Aperture with 3.4.4 as an interim step from the Apple website, but got the message that I had to update from the App Store.
Any help appreciated.
RussCould there be anything interfering with the App Store connecting to Apple's servers? Firewall, antivirus filters? Any problems with your AppleID? Credit card expired, the answers to your security questions too short, an too simple password?
In some cases it will help, to boot into Safe Mode before connecting to the AppStore. Try to load the updates page while booted into Safe mode, see: Mac OS X: Starting up in Safe Mode -
G5 Tower crashes on sleep after Leopard upgrade
I recently "upgraded" from Tiger (10.4.11) to Leopard (!0.5.8). Now, automatic sleep doesn't work. But worse, when I force sleep, the G5 crashes every time (turbo fans come on) within 5 min of sleep - the machine is unresponsive requiring a forced shut down. I have tried forcing sleep when no apps are running (except the OS). I do not have any antivirus SW. I'm thinking of trying to sleep in safe mode to see whether it's any of the apps that load at startup or as root, but other than that, I'm clueless on what to do since this appears to be an OS issue. Comments and strategies would be very helpful.
BTW, there 54GB of free HDD space, there is 2.6 GB of ram and have recently run DiskWarrior on the HDD in case any of this matters.
JohnNice tech note. I've always tried to decipher what was in those logs. This helps but not in this case. I've copied the crash log that was generated below. Incidentally, I also tried booting back into a Tiger mirrored drive (I will keep them until I'm completely comfortable with the Leopard install, WHICH I'M NOT). Slept and woke as it should. So it's definitely the Leopard install but why? I'm still not quite sure what is going on. Do you?

Frequent Kernel Panics on Snow Leopard 10.6.8
I recently bought a used MacbookPro5,1 with a 2,4 Ghz Core2Duo Processor. It was upgraded to 4 GB of RAM and a 750GB HDD by the previous owner. When I received it yesterday, it was running 10.6.3, I think. It worked flawlessly for the first couple of hours. Then I downloaded the update to 10.6.8. No Problems. After that, it wanted to download and install even more updates for iTunes, Java, and the like. During this update process the Macbook had its first Kernel Panic. It was followed by 3 or 4 more during the next couple hours, with no particular pattern. (Browsing the web, gaming, etc.)
I did run a memtest, and it crashed the first time I was running it. However, I was doing other tasks at the same time. The second time, I ran 2 memtests, with absolutely no problems.
The last Kernel Panic occurred while I tried to uninstall the Avast antivirus I had installed, since I suspected it as a cause for the panics. After unistall, I had no more panics.
Today, I used the Macbook for a couple of hours without any problems. I spent a lot of the time playing a 3D game from the app store. No problems. Then, another kernel panic while watching a youtube video, and another a couple hours later while just browsing facebook. I did another memtest, still nothing.
I then uninstalled firefox, thinking it might be the problem, since it was involved in most of the panics.
I was able to use the laptop for a couple of hours, and now it had another panic while watching a video on safari...

I hope any of you guys can help me solve this problem. I really don't know what to do. I really hope its not hardware related. If you need any more information please tell me.I assume you have working installer discs? If so here's a suggestion:
Clean Install of Snow Leopard
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
1. Boot the computer using the Snow Leopard Installer Disc. Insert the disc into the
optical drive and restart the computer. After the chime press and hold down the
"C" key. Release the key when you see a small spinning gear appear below the
dark gray Apple logo.
2. After the installer loads select your language and click on the Continue
button. When the menu bar appears select Disk Utility from the Utilities menu.
After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
size.) Click on the Partition tab in the DU main window. Set the number of
partitions to one (1) from the Partitions drop down menu, set the format type to Mac
OS Extended (Journaled, if supported), then click on the Partition button.
3. When the formatting has completed quit DU and return to the installer. Proceed
with the OS X installation and follow the directions included with the installer.
4. When the installation has completed your computer will Restart into the Setup
Assistant. Be sure you configure your initial admin account with the exact same
username and password that you used on your old drive. After you finish Setup
Assistant will complete the installation after which you will be running a fresh
install of OS X. You can now begin the update process by opening Software
Update and installing all recommended updates to bring your installation current. -
Backing up crashes Leopard!
Since installing and updating Leopard to 10.5.1 on my G4 Mac mini, I have been unable to backup my system since any attempt to do so crashes OS X altogether. I am using a partitioned 500 GB SimpleTech USB external hard drive, partitioned into 2 equal partitions, one for this Mac mini and one for my G4 iBook (though I don't use it for the iBook anymore since getting a separate firewire ext HD for the iBook, which works well for backups). Previously with 10.4, I was able to back up the Mac mini system using the SuperDuper backup software program. Now, with Leopard installed, the Mac mini system backs up a little over half way and then OS X 10.5.1 Leopard crashes completely. This happens whether I use Time Machine or SuperDuper, and has happened repeatedly. I have repeatedly reported the crash to Apple when the screen presents the option, but have of course received no solution and therefore cannot backup my G4 Mac mini. As Time Machine backs up the first halfway or so, it indicates that I have plenty of available space on the external HD and I emphasize that backups were ALWAYS successful with OS 10.4 Tiger. Is the problem my external HD and would it help to try to erase it completely and remove the partition, since it isn't used anymore for the iBook? I find it strange to think that the external HD could repeatedly crash the Mac mini's OS X Leopard during back ups, but I'd be willing to erase it if that would help.
I would be VERY grateful for any help. Thank you.JVIRANT wrote:
Yes, I did. To make sure, I just re-erased it. Also, I'm going to try backing up again, this time with Norton Antivirus AutoProtect off. I'm not sure if that will make any difference. I assume that a USB ext HD should be functional for backups rather than requiring a firewire. Thank you for your ongoing help!
While AV is a good thing, it is not really necessary for a Mac, and it certainly can cause problems with backups and recovering from a backup.
I have never used an AV on either of my MBPs and so far nothing has hit them.
Yes with the Vista and XP on my other partitions I use AVG, but that's something completely different.
I used to use Virex on my G5, but since they started charging, I let it go since they no longer support Leopard free. -
I cannot access my iphoto application on my imac as it says I have made changes in Iphoto using a newer version. We have recently purchased a Macbook Air and this has Lion (as opposed to leopard on the iMac) and we are sharing photos between the 2. I am awaiting the upgrade discs for snow leopard and then to Lion for the iMac but is there a way to access my photos until this arrives?
Do a malware check with several malware scanning programs on the Windows computer.
Please scan with all programs because each program detects different malware.
All these programs have free versions.
Make sure that you update each program to get the latest version of their databases before doing a scan.

We need to upgrade from Leopard to Snow Leopard and then on up the chain. How?
We have an old MacBook running Leopard (10.5.8). Can we upgrade to Snow Leopard and then add others gradually untill we get to the newest version? If so, were can we find a copy of Snow Leopard?
Before embarking on a major OS upgrade, it would be wise, advisable and very prudent if you backup your current system to an external connected and Mac formatted Flash drive OR externally connected USB, Thunderbolt or FireWire 800, Mac formatted hard drive. Then, use either OS X Time Machine app to backup your entire system to the external drive OR purchase, install and use a data cloning app, like CarbonCopyCloner or SuperDuper, to make an exact and bootable copy (clone) of your entire Mac's internal hard drive. This step is really needed in case something goes wrong with the install of the new OS or you simply do not like the new OS, you have a very easy way/procedure to return your Mac to its former working state.
Then, determine if your Mac meets ALL minimum system install requirements.
To install Yosemite, you need one of these Macs:
iMac (Mid-2007 or later)
MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
MacBook Pro (13-inch, Mid-2009 or later),
MacBook Pro (15-inch or 17-inch, Mid/Late 2007 or later)
MacBook Air (Late 2008 or later)
Mac mini (Early 2009 or later)
Mac Pro (Early 2008 or later)
Xserve (Early 2009)
Your Mac also needs:
OS X Mavericks, Mountain Lion, Lion, or Snow Leopard v10.6.8 already installed
2 GB or more of memory (I strongly advise, at least, 4 GBs of RAM or more)
8 GB or more of available space
Next,
If you run any older Mac software from the earlier PowerPC Macs, then none of this software will work with the newer OS X versions (10.7 and onward). OS X Snow Leopard had a magical and invisible PowerPC emulation application, called Rosetta, that worked seamlessly in the background that still allowed older PowerPC coded software to still operate in a Intel CPU Mac.
The use of Rosetta ended with OS X Snow Leopard as the Rosetta application was licensed to Apple, from a software company called Transitive, which got bought out, I believe, by IBM and Appe could no longer secure their rights to continue to use Rosetta in later versions of OS X.
So, you would need to check to see if you have software on your Mac that maybe older than, say, 2006 or older.
Also, check for app compatibilty here.

If you have any commercial antivirus installed and/or hard drive cleaning apps installed on your Mac, like MacKeeper, CleanMyMac, TuneUpMyMac, MacCleanse, etc. now would be a good time to completely uninstall this apps by doing a Google search to learn how to properly uninstall these types of apps.
These types of apps will only cause your Mac issues later after the install of the new OS X version and you will have to completely uninstall these types of apps later.
Once you have determined all of this, you should be able to find the latest version of OS X Yosemite by clicking on the Mac App Store icon in the OS X Dock and then login to the Mac App Store using your Apple ID and password.
You can then begin the download and installation process of installing OS X 10.10 Yosemite from the Mac App Store.
Good Luck! -

WHERE can I find the antivirus software of my IMAC?
There is none. It's already built-in to the OS. You do not need to install any third-party AV software.
