What type of anti virus and malware can i use on my mac

for the past month my mac has been down. it would not start up or i would get the folder with a question mark. i reinstalled on it twice. Dunno if its going to last this time or what so any help would be great. Someone told me it may be my HD but this mac is only 3yrs old. We do not do anything on it expect for pics and music

Additionally, even though your Mac is only 3 years old, all hard drives fail sooner or later - they may last 5 years or more, or they may fail within the first year. So, follow the suggestions, and, in addition, it might be worthwhile to run the Apple Hardware test (that is not foolproof, but pretty good) - run the extended test and post back any messages/errors you get. Here are the instructions:

Do I need to have any type of anti-virus or malware, spyware protection for my Macbook Pro?

My Macbook is a year old. When I bought it, I was told by several people that I would not need any type of anti-virus software or anything to protect my computer because Mac did not get infected that often. However, I have had people today tell me that I do need protection for my computer. My Mac runs about as good as the day I got it, but I really don't want anything to happen to it. If I need to get an anti-virus, or malware/spyware software, what programs would y'all recomend? I am just looking for information. Thanks!

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.
If you find this comment too long or too technical, read only sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates 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.
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 a second 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 necessarily been tested by Apple, 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. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It 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 simply ignore the consequences of distributing codesigned malware.
An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
For the reasons given above, App Store products, and other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. OS X security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is presumably effective against known attacks, but maybe not against unknown attacks. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. XProtect, Gatekeeper, and MRT reduce the risk of malware attack, but they're not absolute protection. The first and best line of defense is always your own intelligence. With the possible exception of Java exploits, 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 amounts 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, or that does something inherently untrustworthy. How do you know what is trustworthy?
Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," 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 visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software that purports to help you do something that's illegal or that infringes copyright, such as saving streamed audio or video for reuse without permission, is unsafe. All YouTube "downloaders" are in this category, though not all are necessarily harmful.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe.
Even signed applications, no matter what the source, should not be trusted if they do something unexpected, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Follow the above guidelines, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself from malware.
7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. Any database of known threats is always going to be out of date. Most of the danger is from unknown threats. 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.
8. 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 will 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. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
ClamXav may be able to tell you which particular virus or trojan it is, but do you care? In practice, there's seldom a reason to use ClamXav unless a network administrator requires you to run an anti-virus application.
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 in the Sharing preference pane. All are disabled by default.
10. As a Mac user you don't have to live in fear that your computer is going to be infected every time you install an application, read email, or visit a web page. But neither should you have the false idea that you will always be safe, no matter what you do. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

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.

As KP has pointed out, there actually aren't any anti-virus programs in the App Store. There are a few that allow you to scan e-mail or stuff like that, and a few that provide you with information about malware and new threats for other systems. But none are available that can scan your iOS device for malware, because the security restrictions in iOS do not permit any apps to have that kind of access to anything. Which means that you also cannot be infected with a virus (unless you have jailbroken your device).
If your account got compromised, that had nothing whatsoever to do with your iPad. Someone simply hacked it remotely. Happens all the time. It's really amazing that, in this day and age, e-mail providers are so ignorant of technology and how their own systems get compromised that they would try to require you to run software that does not exist!

Will re-installing OSX and enabling Save Settings kill virus' and malwares?

Hello
My web pages are slow to load sometimes and I'm wondering if I have a virus or malware that is doing it.
I don't want to use virus checkers or malware checkers because I've heard they are themselves used by the virus writers to plant virus' and malwares.
So my question is; If I re-install OSX while enabling Save Existing Settings, will that remove any virus' and malwares if they are on my Mac?
Thanks for your help.

As there are no viruses for Mac OS X it is extremely unlikely that this is your problem, so let's concentrate on your slow page loading.
Firstly, you need a minimum of 10.5.7 (10.5.8 is better) to run Safari 4.0.3. You show you are using an earlier version of leopard.
Post back if you are not using Safari.
But to answer your direct question: just possibly, so read the following first:
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 from:
http://www.clamxav.com/
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:

The MacScan application can be downloaded from here:

You can download a 30 day trail copy which enables you to do a full scan of your hard disk. After that it costs $29.95.

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), as reported here on December 9, 2008:

You can keep up to date, particularly about malware present in some downloadable pirated software, at the Securemac site:

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 *********** 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.
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:

What RAM do I need and where can I get it from?

Hi all,
I know this is probably a simple question, but I just want to make sure I don't mess up my computer! I have an old school DV iMac, and bought the Mac OS X upgrade not too long after it came out (which is rather a while ago now!), but couldn't install it became I don't have enough RAM. And I obviously have just put it off and off. Now I'm at uni, and want the computer to work as well as it can for my mum, because she's even worse than me when it comes to computers. So, anyway, I need RAM. What type do I need and where can I get it from fairly cheaply? And how much would you recommend I get? My friend says he knows how to put it in, so all okay there hopefully/
My computer's details:
Processor info: PowerPC G3
Machine speed: 400MHz
OS: 9.2.2
Built-in memory: 64MB
I remember being able to get more details than this from somewhere on the computer, but I can't remember where...I haven't used it for 6 months or something, and am obviously getting forgetful.
Hope someone can help. If you need to know anything else, tell me where to get the info from and I will tell you!
Cheers,
Fran
DV iMac Mac OS 9.2.x It's lime green...ooh...

Hi,
I just bought some RAM from Crucial.
If you go to www.crucial.com/uk and follow the Crucial Memory Advisor Tool, you should be able to find the RAM for your Mac.
1 GB sticks are pretty good value at the moment (they've even gone down a few pounds since I bought mine a week ago) and if you enter this code (found it on aonther thread here) you might get a couple of pounds knocked off the total: CUSTOMPC
There's also places like Kingston & Cancom to try, as well as Misco.co.uk. But Crucial select the recommended RAM for your Mac.
Also, when you think you've found the right RAM and want to buy it, try the Apple agent chat, and double-check with them.
Hope this is useful.

This is my first mac - what is the anti virus protocol with a mac?

this is my first mac - what is the anti virus protocol with a mac

Try using ClamXav 2.2.4. If you are not now using a hardware router I highly recommend you do so. Preferably use Ethernet for your local network. If you use wireless be sure it's protected by using WPA2 security.
Use your head and don't download something when you don't know what it is, what it does, or where it's from. Stay off of unknown websites and don't click links if you think you're not sure what will happen.

How can I check for viruses and malware on my MacBook Pro?

I have a MacBook Pro running OS X (10.7.5). I don't have any anti-virus or malware software installed. My yahoo email account was hacked last night, after I had added the account to Mail on my mac (which obviously involved typing in my email account password). I'm now worried that I might have a virus or malwre on my computer as I've had that email account for years with the same password (foolish I know) and never had a problem.
Is there a way to check if my mac has any viruses or malware? Which anti-virus/malware software should I install to protect my mac?
Thanks.

Ever hear of this? I was using Mozilla, and now I'm scared, so on Safari. Even so, I'm worried about doing online banking until I know what's up. Despite that, I did online banking on Safari today, and the pages wouldn't load, or weren't clickable. Also, I'm getting blank screens on Safari. It all started after this happened a number of days ago, so I want to do a scan…. but newish to the Apple world, so don't want to screw things up even more (potentially) - by installing some incompatible malware scanner. From the other day:
has anyone's Macbook Pro ever been hacked? I was using Mozilla, just opened a twitter acct, was trying to cross link with G+, and all of a sudden all this weird stuff was happening: url bars erasing on its own (and fast), pages jumping from window to window, 2 unread msgs in Gmail later marked as read. I shut down and restarted. I don't know if it's a key stroke I did or if I may've been hacked. worried.

Jeff,
after trying to find, and use screen shot, i tried to access reader
downloader... instead, found an offline version of reader. after
installation started getting false reports that appeared as avg pop-ups.
Within task manager, was able to detect virus / worm running 6 - 8
services. immediately disconnected my 'net connection. closed all active
services being run by rogue process. determined it was using two files
named "lastalive0.dat" and"lastalive1.dat" to determine it's own status...
upon stopping it's services it controlled, it would soft re-boot to
resurrect another hijack attempt. tried workaround using secondary boot
(win 7) to no avail. after two days, i transferred personal data to
removable media and am in process of installing debian version of linux.
i thank you for reply and apologize for my tardy response, it was my first
forum experience

What are some good free virus and malware programs?

what are some good free virus and malware programs?

The common census by the old timers on the forum is that you should not have any AV software on your Mac cause its not needed, yet the forums are full of people that have been infected with Malware which the same people help clean afterwards.
This totally befuddles me. I take care of quite a few macs and in the past few years have installed Anti Virus software on them and other than Sophos not catching the latest kinds of Malware that are out in the wild, I have not experienced any of the problems that the so called experts claim that they do.
Over the past few months I have migrated over 50 Macs from using Sophos to now using aVast Free Anti Virus for Mac. Other than getting more alerts of Windows viruses being found in Mail there has been no downside whatsover.
I believe in the old saying that an ounce of prevention is worth more than a pound of cure. So with that I will recommend that you should have some sort of Anti Virus software on your Mac. As I said prior, for now I an recommending avast Anti Virus for Mac. This will protect your Mac from getting infected with malware before you have to come back and ask the experts here how to fix your Mac and get rid of the malware.
When doing a scan I recommend that you only have it set to only show infections. Since it cannot read some compressed files and reports them as an error.

Stopping anti-virus and anti-malware scans from scanning diasabled user files?

Using Windows Server 2008
If I only disable old user profiles, does anti-virus and anti-malware still scan their profiles and all files contained there within? Is this something that will happen regardless of the old users status and during a "whole computer" scan?
And if so, are computer resources still being used for these old profiles?
Thanks!

Hi LaEmperor,
From my experience with different AV softwares, I can say that they continue scanning them as part of the filesystem, despite of being disabled.
I am not sure about your question for the resources, but I´ll give two shots:
1. From the system perspective: basically affects the space that the files from that profile are using. The leave also some information on the Registry hive, on .USERS\ but unless it is a large numbre, I will not be concerned.
2. From the Antivirus perpective: Well, as usual, Disk I/O, RAM, CPU, etc...; so as much as disabled profiles, as much they will add to the usual amount of resource comsumption.
Hope you find this informative.

That's a valid question as your OS is somewhat vulnerable, although most modern malware will only execute on an Intel Mac, there has been at least one that is PPC savy. Your best defense against that would be to keep Java turned off in all browsers.
The problem you will find is that most A-V software these days is also Intel only or requires Leopard.
ClamXav requires OS X 10.5 or above, but you can still find a Tiger version here.
Sophos Anti-Virus for Mac Home Edition looks like it will still work.
