Best free anti-virus mac

Hello.
Recently a new free anti-virus came out at App Store.
I had already VirusBarrier free... no problem until now.
I was wondering if this new Virus Bitdefender is really better.
Is there any problem if I install both of them?
Thanks

There seems to be a bias in favor of ClamXAV among the communities users, have you tried that AV software?
Installing more than one is usually not a good idea as they will see the virus signature definitions in each other and think there is a problem.

    I'm looking for the best FREE anti-virus software for personal use. Suggestions? If you could give me the top 2-3 or those that clearly separate themselves from the pack, I'd greatly appreciate it. Thanks!

    Darien,
    Allan is right it's really not needed for MacOSX, but if you feel you need protection from viruses/malware download and install ClamXav. If you want real time scanning for files and downloads use the Clam Sentry feature. Open ClamXav, go to preferences activate clam sentry, when asked  what folder to watch just enter the / which will monitor your entire system. Hope this helps.

  • What is the best free anti-virus download to use on my MacBook Pro?

    I'm worried that whatever Apple has built into the computer is not enough security. Is there a free anti-virus download for Macs? Do they do the job or do I have to spend money on something better? The download would need to identify and fix the problems. I mostly email, search the internet, sometimes buy things, download Kindle books, do my banking, etc. I would really not want to spend any money if it's not needed. Thanks.

  • Best free anti virus and malware

    Can anyone suggest a good anti virous malware download
    richard

    IOS uses sand boxing. 
    THis is means each app runs isolated from other apps. Apps cannot make system wide changes or change the core OS.
    there is no central file system.
    this means AV software can not work, as it can not scan any files except ones contained in the app itself.
    sand boxing also prevents malicious software from doing anything.
    ios devices can not download any app or executable file from any source but the App Store.
    the App Store scans and checks all apps for malware.

  • Hi looking for a bit of free  anti - virus and firewall for osx 10.8.2

    hi looking for a bit of free  anti - virus and firewall for osx 10.8.2 any pointers also any one used Mac cleaner ?

    1. This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
    2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files. This feature is transparent to the user, but internally Apple calls it "XProtect." The recognition database is automatically updated once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
    The following caveats apply to XProtect:
    It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets (see below.)
    It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
    3. Starting with OS X 10.7.5, there has been another layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't actually been tested by Apple (unless it comes from the Mac App Store), but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. For most practical purposes, applications recognized by Gatekeeper as signed can be considered safe.
    Gatekeeper has, however, the same limitations as XProtect, and in addition the following:
    It can easily be disabled or overridden by the user.
    A malware attacker could get control of a code-signing certificate under false pretenses, or could find some other way to evade Apple's controls.
    For more information about Gatekeeper, see this Apple Support article.
    4. Beyond XProtect and Gatekeeper, there’s no benefit, in most cases, from any other automated protection against malware. The first and best line of defense is always your own intelligence. All known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore reduces to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
    That means, in practice, that you never use software that comes from an untrustworthy source. How do you know whether a source is trustworthy?
    Any website that prompts you to install a “codec,” “plug-in,” or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
    A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn users who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
    “Cracked” copies of commercial software downloaded from a bittorrent are likely to be infected.
    Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. No intermediary is acceptable.
    5. Java on the network (not to be confused with JavaScript, to which it's not related) is a weak point in the security of any operating system. If a Java web plugin is not installed, don't install one unless you really need it. If it is installed, you should disable it (not JavaScript) in your web browsers. Few websites have Java content nowadays, so you won’t be missing much. This setting is mandatory in OS X 10.5.8 or earlier, because Java in those obsolete versions has known security flaws that make it unsafe to use on the Internet. The flaws will never be fixed. Regardless of version, experience has shown that Java can never be fully trusted, even if no vulnerabilities are publicly known at the moment.
    Follow these guidelines, and you’ll be as safe from malware as you can reasonably be.
    6. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good. If you need to be able to detect Windows malware in your files, use the free software ClamXav — nothing else.
    Why shouldn't you use commercial "anti-virus" products?
    Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
    In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
    By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
    7. ClamXav doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so can corrupt the Mail database. The messages should be deleted from within the Mail application.
    ClamXav is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. If you don't need to do that, avoid it. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
    8. The greatest danger posed by anti-virus software, in my opinion, is its effect on human behavior. When people install such software, which does little or nothing to protect them from emerging threats, they get a false sense of security from it, and then they may do things that make them more vulnerable. Nothing can lessen the need for safe computing practices.
    9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use.

  • Free Anti-Virus/Spyware Program?

    Are there any good, free anti-virus/spyware programs out there to protect my Mac? Ones that remove Mac viruses/spyware as well as Windows ones too? I know there aren't nearly as many threats out there for a Mac compared to Windows, but they are still out there so I want to be safe and know my Mac is secure.
    I'm an ex-PC user of many years so I am used to having some comfort knowing I have protection...
    Message was edited by: JerichoX

    there are some trojans and I think keyloggers exist too but they can't be installed without your active participation. meaning you have to download it, install it and enter your admin password. These things are sometimes disguised. there were a few posts recently by people who got a trojan while visiting adult websites the trojan was disguised as a codec that they were prompted to install to view certain content. However, currently that's pretty much the only way something like this can get into your Mac. If you use a standard account for normal computer operation and take minimal reasonable precautions about what you install on your system there is no need for extra protection.

  • O.T.  Free Anti-Virus Software Recommendations Wanted

    Any recommendations on free anti-virus software for the Mac ?

    Some thoughts on Norton on Macs that I saved from another forum:
    Do not use Norton Antivirus. Do not trust Norton Antivirus.
    For starters, there are no Mac viruses. Nada. Zip. None. Paying money to protect your Mac from viruses is like paying money to protect your Mac from vampires.
    Norton Antivirus has two problems that make it worse than useless. First, it has many known and documented bugs (including bugs that can cripple your system in a way that makes it impossible for you to authenticate as an administrator, bugs that can prevent you from re-installing Classic, and bugs that can corrupt files created with Adobe Photoshop and Adobe Indesign).
    Second, it has a history of false positives--incorrectly saying files are "infected" when they are not. In the worst and most dramatic case of false diagnosis, one NAV update wrongly said certain critical VM files used by the system were "infected;" people who believed this diagnosis and told Norton to "fix" the "infection" screwed up their systems but good.
    NAV is also implicated in many kernel panics and other system crashes.
    I'm sorry to be the bearer of bad news, but you have wasted your money on worthless software that can damage your system in an effort to protect yourself from a problem which does not yet exist on the Mac. I advise you to write off the money you spent as a loss and remove Norton from your computer.
    Norton is NASTY stuff. Stay away from anything with the Norton name, especially do NOT let anything with the Norton name (like Norton Anti Virus, File Saver) ever reside on your computer.
    NAV (Norton Anti Virus) can lead to permanent file damage. Files damaged by NAV are not recoverable. NAV can also prevent many PostScript files from parsing, even if not damaged permanently.
    Disk Doctor and Speed Disk are known to cause the kind of directory damage that can lead to kernel panics.

  • What is the best COSTING anti virus

    i need a mac anti virus that i can pay for i do not want a free nti virus cause i dont like them i need to know a good anti virus not like norton that f*ed My Mac Up It said 9 files r viruses to mac os and i deleted them and now i cant install anything on my mac so what s good anti viruses
    and should a do a clean istall of mac os cause now i cant install anything
    AND YES U DO NOT NEED TO TELL ME THAT MACS DONT GET VIRUSES I KNOW
    I Just need a anti virus for some backup sometimes

    No viruses that can attack OS X have so far been detected 'in the wild', i.e. in anything other than laboratory conditions.
    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 (on no account install Norton Anti-Virus on a Mac running OS X):
    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:

  • What is the best free antivirus for mac ox iBookG4?

    Hi,what is the best free antivirus for mac ox iBookG4?

    While no one may be bothering to write exploits in PPC code any longer, at least for Flash, that doesn't mean that there aren't any still floating around. The following doesn't specifically mention PPC/Intel, but that doesn't mean there weren't critical vulnerabilities being exploited for PPC in 10.1.102.64. I wouldn't want to take the chance.
    Critical vulnerabilities have been identified in Adobe Flash Player 10.1.102.64 and earlier versions for Windows, Macintosh, Linux, and Solaris. These vulnerabilities could cause the application to crash and could potentially allow an attacker to take control of the affected system.
    http://www.adobe.com/support/security/bulletins/apsb11-02.html
    And, from TenFourFox
    PowerPC plugins are unmaintained and insecure, and Mozilla is changing the plugin environment
    No major plugin is being maintained for Power Macs any more: Flash stopped updates with Flash 10.1.102.64 in November 2010, and QuickTime 7 for the PowerPC was decommissioned with the release of QuickTime 7.7 and OS X Lion in August 2011. (Tiger users have not had an update since QT 7.6.4 in September 2009.)
    Plugins have special access to the system. When they are instantiated by the browser, they run as if you were running any regular application, which is true even for out-of-process plugins (which were never available for 10.4Fx due to Tiger SDK limitations). Like any buggy or insecure application, they can be exploited or made to crash, and because the plugin runs within the browser, such methods can also be used to attack, spy upon or destabilize the browser as well. They have also been used to attack the network the computer is running on, and a well-crafted attack vector such as that example can run anywhere Flash does, including Power Macs. Because plugins load automatically by default when the page calls for them, your system could be exploited before you even notice.
    Many of these attacks can be mitigated, though not entirely prevented, by the use of add-ons that can block plugins from loading. However, there is still another problem apart from security: Mozilla is changing the environment and the technical requirements for how plugins interact with the system. These technical requirements are difficult to achieve with Mac OS X 10.4, and there are known graphical and compatibility bugs already. It is entirely possible that in the near future, extant PPC-compatible plugins will not function properly or at all.

  • Free anti virus software for nokia 5530

    Does anyone know where you can download free anti virus software for the 5530? i've tried a few sites (even trend micro) but none of the software i've downloaded is compatible with my phone

    The security model of SymbianOS 9.2 and above simply does not allow software to install without the user specifically allowing it and without the software in question being signed with a valid certificate. A phone running S60v3 and above simply cannot be infected with a virus.
    http://3lib.ukonline.co.uk/viruses.htm
    The phone therefore needs no protection against viruses.
    It may, however, need protection against the user! If you accept and install anything sent to you via bluetooth, MMS or e-mail, or if you make a habit of installing cracked warez from dubious sources, them your phone almost certainly will become infected with some form or other of malware, although it will not be a virus. It might be a worm or a trojan. In any event, it's up to the user to behave responsibly.
    Another risk is that the phone may carry Windows or MacOS malware that was copied to it when it was connected in mass storage mode to a computer that was already infected. While such malware will be absolutely harmless to the phone (because the phone runs a completely different operating system on which the malware simply won't run), it could certainly be harmful for the next copmputer to which you connect the phone. The solution here is to scan the phone's mass storage with normal antivirus software on your computer.
