How do i know if my mac has a virus

what can i use to check and see if i have a virus on my computer

If you want to try it for free, install the mackeeper from the apple page. It checks for viruses and tells you if you have anything. Just go to www.google.com and type in mac keeper.

  • How do i know if my Mac has a virus? or any kind of malware? im running OS Mavericks.

    I'm worried because one of my friends opened a website that seemed weird and i dont know if i could of gotten a virus or malware.

    If your friend was using your Mac to visit this web site, you really should only allow your friend to use your Mac from the guest account. If you do that everything they do in the guest account will be erased when they log off you Mac. Also being on the guest account will prevent them from installing anything. That can really be helpful in preventing any such problems.
    To do that just use Fast User Switching to login to the guest account and then give it to them.
    My answer if they don't like that solution is to tell them to go find someone else's Mac to use then.

  • How do i know if my apple has a virus?

    How do I know if my apple has a virus? How do I check?

    What makes you ask? Are you having a problem that you believe is due to some kind of malware? If so, what is that problem? Describe the symptoms in detail... they're probably not due to malware, so knowing what is going on is important.
    If you're just curious about protecting yourself against malware, see my Mac Malware Guide.

  • Hi, i would like to know if my mac has a virus

    hi, i would like to know if my mac has a virus, ´cause in sometimes it works weird

    Ralph is right (of course) about no virus.
    What you are describing seems to be what might happen if all of the system's resources* are gobbled up.
    *When I say "resources" - I mean memory (real and virtual), caching needs, CPU usage etc.
    The web pages you describe have nothing to do with your Mac having been "infected", per se, but that kind of "Pop Over" "Pop Under" malicious JavaScript can certainly gpbble up resources. When you get the Web being mean to you, and have a lot of other APPs open too, you could max out your machine, especially if it is older like mine.
    To help other members answer your question, give as many details as you can.
    Include your Mac Model name and specs such as processor speed, memory, and storage capacity. Please do not include your Serial Number, IMEI, MEID, or other personal information.
    Provide the version numbers of your operating system and relevant applications, for example "OS 10.4.11" , "Quicktime Player 7.6.4",  "Safari 4.1.3"and any other apps you might have open when the misbehavior occurs.
    Describe the problem in detail, and include step-by-step your actions that lead up to °each misbehavior.You seem to be describing at least TWO different bad behaviors
    List any troubleshooting steps you've already tried, or temporary fixes you've discovered.

  • How do I know if my computer has a virus?

    Hello,
    When I am on netflix and click on certain buttons more windows open on my computer. It didn't used to happen so I am worried that my computer has been attacked by a virus. How do I know if it is a real virus?
    Thanks!

    You may have installed one of the common types of ad-injection malware. Follow the instructions on this Apple Support page to remove it.
    Back up all data before making any changes.
    One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those. If Safari crashes on launch, skip that step and come back to it after you've done everything else.
    If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, ask for further instructions.
    Make sure you don't repeat the mistake that led you to install the malware. It may have come from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.
    Malware is also found on websites that traffic in pirated content such as video. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
    In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere  should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
    Still in System Preferences, open the App Store or Software Update pane and check the box marked
              Install system data files and security updates
    if it's not already checked.

  • How do I know if my Mac has been infected with the virus

    I recently was asked to download an Adobe Acrobat reader update but before I was made aware that the current virus was contained in a similar request, I downloaded what I assumed to be a legit update.  I currently do not use my mail program on my Mac so am unaware of any spam being distributed from the computer.  How can I identify if my computer has been infected with this Trojan Horse virus?

    Two Helpful Links Regarding Flashback Trojan
    A link to a great User Tip about the trojan: Flashback Trojan User Tip
    A related link in the tip to a checker: Malware Checker Dowload Link
    A Google search can reveal a variety of alternatives on how the remove the trojan should your computer get infected. This can get you started.
    For now I recommend the User Tip from etressoft to detect and remove:

  • How do i know if my phone has a virus?

    my phone is turning on and off and is opening applications by itself. it is also calling people in my contact list and deleting text messages. it is literally possesed. i fear it is a virus. how can i know for sure?

    iphones do not get viruses unless they have been jailbroken.  I suggest you try this: hold down the Sleep/Wake button and the home button together until the apple logo appears (ignore the ON/OFF slider) then let both buttons go and wait for phone to restart (no data will be lost).
    If that does not do it restore the phone from a backup, failing that you might need to restore the phone as new

  • HT5244 how do I know whether my mac has the malware?

    I've just installed the java fix, but I don't whether it's to late, ie whether the malware is already installed on my mac. Is there any way to check it, without buying an antivirus (cf. should be an advantage of the Mac so far). Cheers

    ClamAV is a free antivirus too that you can run once to determine if there is any sign of it.
    Apparently, ClamXav has not been doing that well in detecting the latest versions of FlashBack. If you are looking for a free A-V product with a more aggressive update policy, it might be worth checking out Sophos AntiVirus for Mac Home Edition.

  • HT3986 how will i know if my mac has windows 7 already?

    Press and hold the option key when you power up your computer.
    Did you install Windows? Did someone else install Windows for you? If not, then you don't have Windows.

  • How do I know if my iPad has a virus

    My iPad has started behaving strangely while I'm using safari.
    It allows me to open google and then search my chosen point, it delivers the findings and allows me to open the chosen site. However when I try to navigate further on the same page or return to the google search results it freezes and I have to start fom a new page. Culd I have picked up some kind of virus? And how do I scan my iPad for virus etc.
    Thanks
    John1022

    I'm not aware of any viruses for iOS devices.
    Try clearing Safari's cache : Settings > Safari > Clear Cookies And Data (Clear Cache on iOS 4) and also Clear History
    If that doesn't fix it then try closing Safari completely and then re-open it : from the home screen (i.e. not with Safari 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Safari app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
    A third option is a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

  • Help!!!!! How do I find out if my Mac has a virus

    Help!!!!!! I was searching the web and some window popped out (Apple window) recommending that I download something to do with antivirus. I guess the website that I was about to visit had a virus. I clicked ok and the next thing I know some things started popping out that the website I guess had a virus and that (trojan and other stuff) oh and some window stuff popped out. However, I just pressed clear on everything quit Safari and nothing else has happened. How do I know if my Mac got a virus for sure. So far everything is fine but I just want to make sure. Anybody please, any suggestions!!!!!!

    That is web-phishing. You should avoid such sites. You don't have a virus. Turn on your browser's ad blocker which may help prevent such pop up windows from occurring.

  • How do you know what version Mac OSX is on ANOTHER drive?

    How do you know what version Mac OSX is on ANOTHER drive without starting that drive
    and seeing the system profiler? In fact, because the drive wont start up, Now I am wondering if it is pre-intel. ? CMD-I doesn't do it. Thanks

    Why mess with this? Well, I got the HDDs and the enclosure from my previous PPC, so I'd like to make use of it all without $pending again.
    I don't see any problems with using the card and drives on your new Mac. Hardware is too pricey to just leave behind if you can't help it. With the new drivers I suspect you'll be able to use your drives, I just don't think you'll be able to boot from them if the interface card requires drivers. They should still be very fast storage devices, and probably reliable due to the ongoing support the vendor has provided.
    I went through the same type of issue when I bought my Dual G4 1.42 Tower (upgraded from a Quadra 840AV ). Several of my devices were SCSI (I was into SCSI Wide/Fast drive arrays at the time for video capture), and I was able to use an Adaptec card for scanning for several years with Jaguar and Panther. I'd spent quite a bit of cash to ensure high quality and performance and didn't want to loose all of the investment. Eventually the SATA hard drives and other USB and Firewire replacements became so cheap and performance improved enough that loosing SCSI with Tiger was not a big deal. I do think I should get about 5 years of hardware compatibility with most products and I keep older Mac's around for dedicated services as long as they aren't a costly maintenance issue.
