How much truth in email solliciting about 'VIRUS' threats?

I keep receiving email from a company that tells me: "...Macs don't get viruses. THINK AGAIN!..."..trying to sell me a 'Virus Barrier'.
I have searched all info I could find on virusses (viri??) on these forums, and came up zero on real threats. As far as I can tell there is no known virus for OSX.
Can someone enlighten me?
Thank you in advance!
Regards,
Mildred.

Hello Mildred.
You will receive pros and cons regarding this issue but if some software company (or retailer) trying to sell their antivirus software must resort to these kind of tactics in order to do so, I would think twice before spending any money on it as you obviously are.
Do a Google search for OS X viruses and see what you come up with.
The most important protection is between your ears. Never open any email attachments received from someone you don't recognize or until you can confirm who the sender is and what was sent and don't use P2P software like Limewire which allows for downloading files from completely unknown and untrusted sources.
The same when downloading software or files from a website. You should do so from a known and trusted source only.
If you are prompted for your admin password out of the blue or unexpectedly to install anything, you should always decline.

  • HT4597 How much will iCloud email cost?

    How much will iCloud email cost if all I use in my .mac email account and nothing else? My equipment doesn't support iCloud, and therefore email is all I'll be using.

    iCloud is free and comes with up to 5 GB of storage in the free package, you can purchase more storage space if you want, however for Mail only I very much doubt you will need more than 5 GB.

  • How do I stop email notifications about a facebook account I don't have?

    Recently started receiving numerous emails to my iCloud account about a Facebook account that I don't have. How to stop these??!

    Pat,
    As I understand it, if I change all of my email preferences to "No," which I have already done as shown in the original post (above), I should stop geeting those email notifications. And, further, if that does not work I am to send a screenshot of the Notifications Preferences (above) and a copy of the "Reply to"  address of one of the emails that I am getting. I am having trouble doing that..
    I assumed that they did not want the "Do Not Reply to" email address. So I am sending what I hope is the Reply toaddress from one of your emails that I received:
    [email protected] I hope someone can use that to help me stop those emails.
    I have no idea how or why I started receiving this overwhelming number of emails in the past week.. I did not knowingly join any Forums or respond to any emails related to Adobe.
    When I browse under "My Things" I find that I am not subscribed to any Forum. So I really do not know what it is I need to change.
    I will appreciate any help you can give me that will stop these emails.

  • How much email is downloaded?

    When my email syncs over the air to the email server it pulls down the various emails to my phone.
    How much of the email is pulled down to the iPhone?
    EG: If the original email is 3MB how much does the phone download? I do not see an option for this. On my Windows Smartphone I can set how much of the email to download - Just the headers, xx KB or the entire message.
    I am concerened that the iPhone pulls a small part of the email initially which is fine but when you click to open it, it connects again to the server to download the remainig part of the message which can take an age over GPRS.
    This is my understanding how it works but I may be wrong....

    This is one of the aspects of the iPhone's email app which is bothering me. I love everything about the phone except the email.
    For comparison I'm coming from a 2 year old Samsung phone, not a 'smartphone' (model D600). The email app on the Samsung let's me set how much of message to download (I set it to Headers only). It will then show me the total size of the message so I can decide if it's practical to download it.
    I can also set it to delete selected or all messages from the server which is great for managing email when I'm on the road and is very useful when I get a large email that I don't need to see and I'd rather not have to download again at home.
    The iPhone is rather inscrutable about what it's doing with email, and the 'remove from server' option doesn't work with POP email as others on this board have reported.
    So the iPhone email app is lacking in comparison with the email app on an older, not especially powerful handset.
    I'm hoping future updates will enhance the mail app which seems to be the least 'finished' app on the phone.

  • Is it possible to upgrade my macbook air 13" from 1.86 GHz 128 gb flash and 2GB memory to the 2.13 GHz  256 and 4GB memory, how much would it cost?

    About the only thing that "might" be able to do is upgrade the SSD. OWC sells SSD upgrades for that unit. You would have to contact Apple though to verify that no warranty issues would apply when making the upgrade.

  • How much faster is a Xeon proc vs a Core DUO proc?

    I recently purchased a MBP 2.6 after returning a MP 2.8 8 core because i felt 6 of the cores were going to waste and it was all overkill. I edit video , edit photos , you know PS , FC and the works but Im hoping i made the right decision. So far it seems the MBP is right up to par with the MP if only by a difference of a few seconds on certain tasks. Is it true that there are no appz that take advantage of the 8 cores making it useless in the present? I need a powerful workstation for my work and portability weighed my decision , but why would anyone buy a machine that cannot be used to its full potential? So far I have no complaints and I would love some feedback from others in the same situation. THanks.

    Thanks for your input. It is obvious that the MP is faster , my question is just how much, If we are talking about a few seconds that doesn't bother me and so far I haven't seen much a difference at all except in Poser 7 which utilizes more cores. That was to be expected though. Photoshop does NOT yet utilize more than 2 cores and CS4 is rumored to be the same. That is what is most important to me. Space is no issue I have 4 externals a and I drag and drop what i need for that day or week. The portability just outweighs the slight speed decrease by so much in my book. I mean who really wants a desktop box computer in this day and age?

  • I just purchased MBP and it is my first Apple computer. How concerned should I be about virus software and what do you recommend for security software?

    I just purchased MBP and it is my first Apple computer. How concerned should I be about virus software and what do you recommend for security software?

    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, 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 (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 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. How do you know whether a source 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 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.
    5. 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 never a good idea, and Java's developers have had a lot of trouble 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, Java on the Web is 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.
    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. In Safari, this is done by unchecking the box marked Enable Java in the Security tab of the preferences dialog.
    Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a specific task, enable Java only when needed for the task and disable it immediately when done. Close all other browser windows and tabs, and don't visit any other sites while Java is active. Never enable Java on a public web page that carries third-party advertising. Use it only on well-known, password-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 these guidelines, and you’ll be practically as safe from malware as you can be.
    6. 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. 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 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.
    8. The greatest harm done by anti-virus software, in my opinion, is in its effect on human behavior. It does little or nothing to protect people from emerging threats, but they get a false sense of security from it, and then they may behave in ways that expose them to higher risk. 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 in the Sharing preference pane. All are disabled by default.

  • How much of my data plan is used to display emails on phone?

    I am very new to having a smart phone, so i have lots of questions. I linked my phone to me email account and it displays them on my phone. If I just browse the list of emails without opening any of them, I am curious about how much of my data plan (1G) I am going to use. I know I will use more if I open them, but if it uses a lot of data to merely have them displayed, I will disable it.

    There are some options in your email client which would obviously affect how much data is used. That and the amount/type of emails you receive.
    Do you have your email client set to automatically download attachments? This would increase data, especially if you receive a lot of email with attachments.
    It would also depend if you have your client set to download the email when it is received, not when opened.

    My iMac (late 2010 model) desktop's hard drive is fried (was about 200GB). How much am I expecting to pay for a new one and retrieve my information?

    As you can see Erin, trying to recover information from a hosed drive can be very expensive. 
    I would suggest first the OWC site as well. You can get a new drive of choice in size there.
    I would also get the voyager  http://eshop.macsales.com/item/Newer%20Technology/VOYQHDB1.0T/
    and..
    http://eshop.macsales.com/item/Prosoft%20Engineering/DGDR3BUN/
    http://eshop.macsales.com/item/NewerTech/TOOLKIT11/
    Wth your lap top and these folllowing tools your are set to change out the drive, reload OS and then with
    the voyager pop in the old iMac drive and with the Prosoft software, try to mount and recover the files. Data Rescue is very good at this " if " the drive is not totally mechanically hosed. Drive Genius is very good at a number of things too. Nothing replaces the old adage of Back Up Back up Back up.
    The voyage I listed can become the new backup drive for you.. your choice of tools: Time Machine or by cloning via CarbonCopyCloner or by what I use SuperDuper! IF you want to be really kewl.. both. By that I mean cloning and Time Machine.
    It will take you an hour to swap out the drive and spring clean the iMac.. there is a hundred how too,s on you tube.
    Hope this helps. Remember if is always when a drive will fail..they all do. I tell the people I support that Harddrives are good for 15 min.. to when they don't work. They will all fail.
    Apple Geniuses are very limited to what they can and will do as far as file recovery.
    Your best bet is to try to do it your self first. There is lots of help out here and you are not the first.

    I have a 2007 Mac OS X 10.5.8. How do I go about bringing everything on it up-to-date? Maybe refurbishing it? How much might that cost approximately?

    Okay so there are a few things you can do to bring your MacBook up to speed. You may find, however, that purchasing a new computer will be more cost effective for you.
    Adding RAM - this is one place you can get very good value for your money. Max out your MacBook's RAM.
    Purchase and install a larger hard drive. If you've been running out of drive space or just want more, hard drives are inexpensive and easy to install.
    Update your operating system - You can get Snow Leopard for $29 from Apple. When it comes out next month you can then get Lion for $29.99 from the Mac App Store. Unfortunately as of yet there is no way known to upgrade directly from Leopard to Lion.
    Add an external hard drive to your system for backup. This is always a good idea to have, as data that is in only one place is vulnerable to loss if your hard drive fails.
    Update all of your applications. Many can be bought online now through the Mac App Store, which has made it easy and inexpensive for applications that are available there.
    Things you cannot upgrade -
    Your MacBook's processor. This is the brain of the computer and a faster one will give you a speed boost in some applications. It is part of the logic board so you can't put a new one in.
    Video card - also part of the logic board.
    Interfaces such as FireWire, USB, video out, audio in and out.
    If you need any of these, look for a newer computer.
    Hope this helps you out.
    Best of luck.

  • How much do you care about sound quality in your Home Theater?

    Many people sweat over the smallest details when getting a video device (TV, projector), but do not think much about the integration of a sound system in their room.  Too many people think that a large TV with an off the shelf sound system will make a great home theater system.  Unfortunately, many stores can't even demonstrate the integration of video and audio as evidenced by the huge wall of TVs and a small section devoted to surround sound systems.  How is a consumer to build a home theater if you can't hear and see what is possible.
    So my question is, how much do you care about sound quality and what have you done to get the most out of your system?  For instance: Have you applied sound absorption materials to your walls, have you sweated speaker placement, have you plotted your room's anti-nodes, have you controlled your light levels, have you calibrated your speakers, etc.
    Believe it or not, your room's acoustics and the proper type of audio equipment and speakers play a much LARGER part in your enjoyment of anything that you watch.  You just can't throw some speakers into a room wherever you want and expect to have an engrossing experience.
    The reason I ask is that I don't believe that many people care about sound quality since a large percentage of the population think that portable digital audio players sound fine.  I would like to be proven wrong.  My other goal is to raise everyone's awareness that you need to think about more than just a large TV in order to build your home theater.
    I do not work for Best Buy and am not affiliated with them in any way. I like HT and want to help people improve their HT experience. "There is a LOT more than just having a TV to make a home theater"

    It really depends - I am working since the last 2 years on an very large Applet (~650 classes / 1.5mb classes) which had design-time comptibility with MSJVM and Netscape-1.1.5.
    Now 2 years later the applet is still not finished although I am pretty sure we would already be shipping if only our managers would not had been that stupid to decide 2 years back to support obsolte jvms.
    Since Netscape-4.x is dead and MSJVM useage really decreases dramatically (I guess it won't play a role in 2-3 years) I only can recommend to not target to the msjvm any more.
    its really ugly and its buggy, whereever you look bugs, bugs, bugs.
