what to do about a virus that uses your mac to send email?

It's highly unlikely that your Mac has a virus, since no virus, worm or trojan has been reported, much less confirmed, as having the behavior you mention. As LB suggested, most likely it's your email account itself that has been compromised, or some other computer (a Windows system, almost certainly) that has your addresses on it has been infected.
Check the "sent" folder for your email account and see if the bogus messages are shown there. If they are, that at least would verify that the emails were sent via your email account. Report back and let us know whether your email account is POP, IMAP or Exchange, and who your email host is.
If the messages are not shown anywhere in your "sent mail" folder, then someone has almost certainly gotten hold of your contact list and spoofed your email address.
Regards.

  • I've been hearing in todays news about a virus that can affect mac computers.  When purchasing my Mac computer I was informed I didn't need virus protection.  What do you advise now?

    Currently my mac doesn't have additional virus protection software.  When purchasing my mac 4 years ago I was told it wasn't necessary because it was so rarely needed due to Mac's Encryption etc.  With today's news I hear that it possible the current virus or bug that is out there is aimed at Mac's especially.  What is the advice now?

    It's not a virus. It's just the latest scare tactic promulgated by popular media outlets to ensure the uninformed among us remain uninformed. The fact that you (or they) characterized it as a "virus" is proof of that, on its face.
    What is the advice now?
    If you are running a web server, apply the patch by downloading it from the GNU project archive. If you don't know what that is, how to obtain it, or how to apply it to your server, then you are not affected and there is nothing you need to do.
    Apple announced they are "working to quickly provide a software update for our advanced UNIX users."
    There are plenty of bad things that could happen to a system due to existing vulnerabilities, known or unknown. There is no reason for any more concern today than there has ever been. Bash has been included with OS X for years, perhaps since its inception, and the particular flaw that was just discovered may have existed for years prior to that.
    Similar vulnerabilities may also be discovered and exploited, now or in the future. The resulting effects, if there are any, cannot be accurately predicted.
    Until then:
    Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them.
    Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.

  • What happened to the "lock" symbol that used to appear when on a secure site? I haven't seen it since the last update, so it's either moved or you took it out. I really miss it!

    What happened to the "lock" symbol that used to appear to signify that you were on a secure site? I haven't seen it since the previous update, so it's either moved & I haven't found it, or you took it out. If you did, I want it back!

    It's stuck on a yellow question marked "multimedia audio controller." It doesn't like the CD drivers or the drivers snarfed from the aborted "you don't have an sb controller installed" pull from windows\temp\CF whatever it was. It's 3am and I've been trying to get this stupid thing running for 7 hours now. I'm going to bed. I will see if it is any smarter tomorrow morning.
    It was running great until I did an "update from the web." If I hadn't have done that I'd have no complaints. Now it's hosed and I can't even get back to where I was before. I'm not impressed with creative's installation procedure.
    However, there are many people complaining about the "you don't have an SB installed" problem. Creative needs a "delete everything" button, and an "install all new drivers" button. Take a page out of ATI's book in the number of headaches created by windows installer and come up with a way to fix them yourself. ATI did. This would at least get me back to the BSOD, which right now I'm longing for.
    This is on a shuttle st6g4 with a disable ac97 sound nonsense with those drivers removed.

  • What  is the best anti-virus software for my Mac?

    What is the best anti-virus software for my IMAC?

    If you are still using OS X 10.4.x "Tiger" please confirm.

    Use what Apple already provided.
    There will always be threats to your information security associated with using any Internet - connected communications tool:
    You can mitigate those threats by following commonsense practices
    Delegating that responsibility to software is an ineffective defense
    Assuming that any product will protect you from those threats is a hazardous attitude that is likely to result in neglecting point #1 above.
    OS X already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
    A much better question is "how should I protect my Mac":
    Never install any product that claims to "clean up", "speed up",  "optimize", "boost" or "accelerate" your Mac; to "wash" it, "tune" it, or to make it "shiny". Those claims are absurd.Such products are very aggressively marketed. They are all scams.
    Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources.
    Illegally obtained software is almost certain to contain malware.
    "Questionable sources" include but are not limited to spontaneously appearing web pages or popups, download hosting sites such as C net dot com, Softonic dot com, Soft pedia dot com, Download dot com, Mac Update dot com, or any other site whose revenue is primarily derived from junk product advertisements.
    Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
    Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
    Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
    Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
    Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
    Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
    Don’t install Java unless you are certain that you need it:
    Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
    Java can be disabled in System Preferences.
    Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
    Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
    Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
    Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
    If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
    Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
    The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
    OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
    Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
    If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
    Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
    Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
    Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

  • After installing the new Yosemite OS on my iMac I can no longer send email. I can receive email, but not send. I use gmail and can send email on the gmail (google) site, but not on "mail" on my iMac. Any others with this problem? What should we do?

    After installing the new Yosemite OS on my iMac I can no longer send email. I can receive email, but not send. I use gmail and can send email on the gmail (google) site, but not on "mail" on my iMac. Any others with this problem? What should we do?

    My gmail, which is correctly configured for Mail with gmail SMTP and Google IMAP, works for awhile on Mail, which I leave open while working on other applications. But several times a day I get msg from Google: "We recently blocked a sign-in attempt to your Google Account" . . . and requiring me to verify my account details, re-enter passwords, confirm security settings (or change them from "disable" to "enable less secure methods" and so on). In Mail I also have tried "taking all accounts online", and re-entering my gmail password inside Mail account settings. These steps successfully re-set comms between gmail and Mail ... for awhile, then it happens again. Enough occurrences over a work day that I just quit Mail and revert to accessing gmail directly. Apple Care advisor and an Apple knowledge base article say that Apple can't deal with this, as gmail is third-party app, and they refer me to gmail, and so far I've found nothing helpful there.
    From today I also have several instances of a window saying "Mail has unexpectedly closed" and asking me to Re-open it.
    I also use Yahoo mail, which stops working with Mac Mail at the same time as gmail, but I do not receive notices to re-verify from Yahoo.
    I recently upgraded from Mavericks to Yosemite. The Mail problem happened occasionally with Mavericks but is far more frequent with Yosemite.

    The system doesn’t recognize or capitalize the word (I) or the first word of every sentence. Another really annoying thing about the integrated mail on your Mac computers is the fact that the system learns the word as you type it more and more instead of highlighting it as incorrectly is this is a word that’s being misspelled. Can Apple fix this bug to make it user friendly as if you were using Office or a Word Document?

    You hit the target CT.
    It’s only fair that if Apple is going to integrate Mail into Mac PCs, it would be nice if the system does it for you like Office or perhaps Outlook. I just don’t to use Outlook although I have it installed and ready to use, but instead use Mail which comes with Mac OS already.
    I hope to make some sense here.

  • HT1338 What is the best Anti-Virus to install on Mac OS X 10.6.8? Which one is the most effective?

    Dear all,
    I would like to get more references about which  antivirus program could be more powerful and effective to maintain the Mac OS X 10.6.8 secure.
    Many thanks in advance,

    Hello:
    NO anti-virus software is needed (or desirable) for a Mac running OS X.  There are NO viruses that affect a Mac running OS X - none.  You will hear that some malware exists, but that is preventable by avoiding strange sites or downloading from unknown sources.

  • My ipod 5th gen says it is connected to the internet and i can go on apps that require an internet connection but whe i try to use the weather or another app that uses your current location it cant find me???

    My ipod 5th gen says it is connected to the internet and i can go on apps that require an internet connection but whe i try to use the weather or another app that uses your current location it cant find me???

    If you open the Maps app where does that say you are located?
    For location the iPod uses the location of nearby routers that are in Apple's database of routers and their location. Thus it appears that Apple's database is incorrect. You do not have to be connected to the router, just within range.
    Apple periodically updates their database based on information they obtain from iPhones, The iPhone has to have turned on the option to send info to Apple. no one has found another way to get the location of a router added/corrected.
    You can confirm that by going to well-know place with wifi like Starbucks or McDonalds

    Since the iPod touch doesn't have an LCDflash like the iPhone any app that would turn on the LCD flash on the iPhone into a "flashlight" wouldn't work with the iPod.

    Welcome to the Apple Community.
    I have seen previous versions mentioned in a pop up message before on iCloud.com, but I'm not really sure at all how it would help, as I couldn't get it to do anything.
    The best advice I have at this time is to back up your work on your iOS device by regularly saving it to iTunes, if anything goes wrong you can then either load it into the numbers app again on the device or recover it via iTunes on your computer.
    My syncs are immediate, I never get chance to see if it works in the background, sorry.

    Kappy's Personal Suggestions for OS X Maintenance
    For disk repairs use Disk Utility.  For situations DU cannot handle the best third-party utilities are: Disk Warrior;  DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. Drive Genius provides additional tools not found in Disk Warrior.  Versions 1.5.1 and later are Intel Mac compatible.
    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.  Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger.  These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
    OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
    I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
    For emergency repairs install the freeware utility Applejack.  If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
    When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
    Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
    Carbon Copy Cloner
    Data Backup
    Deja Vu
    SuperDuper!
    SyncTwoFolders
    Synk Pro
    Synk Standard
    Tri-Backup
    Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
    Additional suggestions will be found in Mac Maintenance Quick Assist.
    Referenced software can be found at CNet Downloads or MacUpdate.
    Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.

  • Error Message when using Photoshop Element 9 sending email

    I was using Photoshop Element 9 sending email on Windows Live Mail.
    It was working perfect.
    A week ago, my computer had the problem and need to format and reinstall everything again.
    After that, when I used Photoshop Element 9 to send email using Windows Live Mail 2012.
    It came up error message in below:
    "Elements Organizer could not finish creating your E-mail message.
    Alternatively, you can use the Adobe E-mail Service via the Elements Organizer Preferences dialog."
    I don't want to use Adobe E-mail Service because it is very limited for email function such as attached another files or change email contents.
    Would you please give me some idea how to solve the problem ?

  • Can I use DeliveryManager just to send email with no document?

    Can I use "oracle.apps.xdo.delivery.DeliveryManager" to just send email without any document attached? or
    Is this only used to deliver the documents by email?
    I just want to use DeliveryManager just to send email with content in the body of the email. I am using BI Publisher API.
    Can any of you provide sample input for the above?

    Hi,
    You can use iMovie to record the message and save it as an email sized item and send the file as email like before.
    For those iChat AV users without a Cam and the AIM users without a cam you can do One-Way Viedo chats.
    Once you have a recorded Video file you can also drop the file on any Buddies name in you iChat Buddy list rather than using email.
    For those using other services you can set up a Jabber account and enable the required Transport/Gateways and send the files that way.
    http://www.jabber.org.au/ichat = Australian Page
    AllForces
    These are the two main information pages on how iChat can connect to the other IM services.
    Jabber Public Server list
    That would appear to be everybody.
