Possible malware

How will I know if I have a virus or malware on my MacBook Air.  I update every time that I am informed, so I do not know if something he infected since the last update.  Any advice would be appreciated.

If you are concerned about Mac OS X malware, monitor behavior strange or unexplained slowness.

If you are concerned about some malware from Windows, use ClamXav or a scanner of Windows.

  • Unable to access several sites and install apps in the appstore. A possible malware issue. What should I do?

    Hey guys,.

    I am using a 8 GB Mac Mini with an i5 processor clocked at 2.6 GHz Mac OSX Yosemite 10.10.5 (14F27).

    I don't have problems with this until I visited a torrent site (I hate invited but unfortunately I did this time). Since that unfortunate activity, I get mackeeper pop ups and my search engines by default on all my browsers like Safari, Firefox and chrome automatically replaced by trovi. I can't access to 90% of websites like YouTube except facebook, twitter, Netflix, gmail, google, yahoo and other email clients. I get a "cannot connect" on firefox and messages error 'Safari cannot connect to the server. I checked with the ISP settings and proxy but no problem there as my other devices such as the ipad and the iphone apple work fine on the same wifi network. I erased all the extensions, cookies and cache but without success.

    I am also unable to access the app store to install applications. I wanted to make its own memory and a removal of the malware, but couldn't that since the appstore could not contact the server.

    I mainly use this machine for audio production and browsing through Logic Pro X.

    What is a malware problem? If so, how to fight that? Should I format my HD and upgrade to El Capitan? Who will solve the problem?

    Kindly help.

    See you soon,.

  • Possible malware of plane? Does not connect to AT & T in turn...

    A week ago I was traveling for work. Until my flight home on Wednesday, my iPhone 6 worked perfectly. I used the usb port under my seat and connected my phone, so I could load it. I also used the wifi service on the plane for the Delta app and watch in flight on my phone for free entertainment. After landing and trying to connect to my service provider, my phone has been indefinitely "search...". ». I turned off and turned on, went in and out of shot data power on and off several times, flight mode and hard reset a couple of times. Nothing has worked. I left the airport and went to 40 minutes from the hotel and it is as if by magic a tower and my LTE was back. It was the only one back 10 minutes. Upper left corner then don't read 'no service '. This lasted through the weekend where I have traveled throughout the metropolitan region and to a different State. I couldn't get service anywhere.

    Today, I got home and restored to factory settings, then restored my phone to last synchronization, which was AFTER I came back from the initial flight. Then, the phone connected to LTE right now and took some time to sync all my music files. After he finished syncing, I removed the phone from the usb and she soon loses service again. In a last effort, I took the SIM in and out of the ditch. Always read 'no service '.

    So I drove to the Apple Store and they told me that they could not look at him until later this week. Quickly, an employee made a 'reset network settings' and popped the SIM inside and out. Then, the phone was unable to read the sim card over and says "No Sim". I stopped in the AT & T store to get a new sim card, did not work, still don't read 'no sim '.

    I don't have not returned home to restore the phone to factory settings and then restore backup. It is currently connected to my laptop via USB and still transfer files from backup restore. It IS connected to the LTE but I'm afraid that there will soon be "no service".

    My question is, is this a hardware or a software problem? Could my phone picked up the airplane malware via wifi or usb? Could the plane Delta network put some kind of software (non-malware) which can be screwing things up? I feel I have tried everything...

    If you reset the phone to default settings, WITHOUT restoring from a backup, it works well, then?

    There isn't any value in the default factory restore and then restore backup if there is something in the backup that ask you questions. Try to remove the WiFi configuration for gogo.

    Also, check the configuration of the wireless network that you are connected and see if there is anything that is configured for a proxy server or something like that.

  • Possible malware on Mac - is Adobe Flash Player install Manager application legitimate?

    I have a macbook pro and I am running 10.10 OS. My browser is Safari 9.1.

    Flash player NPAPI plugin version 21.0.0.242 is installed.

    Flash PPAPI plugin player - is not installed.

    Protection service 5/7/16-a identity to which I am subscribed sent a message saying that my Adobe password has been hacked. I changed the password.

    05/15/16, 1 AM-while you browse using Safari a popup appears saying that it needed to update my flash player. (Stupidly), I clicked on "OK".  The window asked if I wanted to install the MacGuard, MacSecurity and another application. I clicked on 'no' to each, then "continue." He then asked my administrator password to install Flash Player. Well I type the password, and I closed the window we'd send her to install some files which warned me that something was wrong. At the end of the installation has changed my Yahoo homepage. I ran Malwarebytes. Malewarebytes identified some suspicious files which I deleted. Then I restarted my computer. 

    I just noticed a file in my Utilities folder called Adobe Flash Player install Manager. It was created on 09/05/2016 and changed 12/05/2016. I don't remember installing this application. Also, I have "notify me to install updates" and I don't remember notification.  Is Adobe Flash Player install handle (located in the folder Utilities-see below) an application legitimate or should I delete it? When I impulsively tried to remove a few minutes ago, asked me my admin password. Before we continue I hope get some forum members advice. It belongs in the utility folder or do I have to remove it using my Admin password?

    Utilities folder image.jpg

    Thanks a lot for any assistance.

    Hello

    Unfortunately, it does not appear you have received a notification of update of Flash Player false as MacGuard MacSecurity not the third-party products available for installation of Flash Player and the official Flash Player installer modifies not the browser's default homepage or the favorite search engine.

    The official Flash Player installer has an application called Adobe Flash Player install by in the utilities directory, however, at this stage, it is difficult, at best, to know if this file was created with the Flash Player installer legitimate or not.

    I have recommended to perform a clean uninstall.  See the FAQ How to perform a "clean installation" of Flash Player in Mac OS X for orientation.

  • Continuing to malware / adware problem

    Hello

    I have finally upgraded to El Capitan at last week. I had no problem until today when I downloaded a new Java Update, which I think may have also installed some sort of adware / malware on my system. Since the installation of new advertising tabs open (on both Firefox and Safari) when I click on some normal links on some sites. I also see underlined green links ad on some pages.

    I tried all the tips I can find online, including of Malwarebytes, Avast, reinstall browsers, try a new user, follow the instructions to remove "DownLite" etc. I also checked the LaunchAgent and LaunchDaemons folders in my library, and they seem to be something unusual.

    Any help with this would be much appreciated because it becomes extremely frustrating Apple have advised me to reinstall OS X, but I would try other options first as it may seem a bit drastic!

    Thank you very much

    You may have installed ad-injecting malicious software ("adware").

    Do not use any type of product, "anti-virus" or "anti-malware" on a Mac. You have already seen that it does not work.

    Save all data first.

    If you are not already running the latest version of Mac OS X, update or upgrade in the App Store you risk adware remove automatically. If you are already using the latest version, please log off or restart the computer. Still, some types of malware will be deleted, not all. There is no such thing as the automatic removal of all possible malware, either by OS X third party software. That's why you can't rely on software to protect you.

    If the malware is deleted in your case, you will still need to make changes to the way you use your computer to protect you from new attacks. Ask if you need advice.

    If the malware is not removed automatically, see below.

    This simple procedure to detect any type of adware that I know. Disabling is a procedure distinct and better still.

    Some legitimate software is funded by advertising and may display advertisements in its own windows or in a web browser while it is running. It's not malware and it may not appear. In addition, some Web sites display advertising intrusive popup that can be confused with adware.

    If none of your web browsers work well enough to carry out these instructions, restart the computer in safe mode. The malware will be disabled temporarily.

    Step 1

    Please triple - click on the line below on this page to select it, and then copy the text to the Clipboard by pressing Control-C key combination:

    ~/Library/LaunchAgents

    In the Finder, select

    Go ▹ go to the folder...

    from the menu bar and paste it into the box that opens by pressing command + v press return. Open a folder named "LaunchAgents", or you will get a notice stating that the file cannot be found. If the file is not found, proceed to the next step.

    If the folder opens, press the combination of keys command-2 to select the display of the list, if it is not already selected. Please don't skip this step.

    There should be a column in the update Finder window. Click this title two times to sort the content by date with the most recent at the top. If necessary, enlarge the window so that all the content show.

    Follow the instructions in this support article under the heading "take a screenshot of a window." An image file with a name starting in 'Screenshot' should be saved to the desktop. Open the capture screen and make sure it is readable. If this isn't the case, capture a small part of the screen indicating that what needs to be shown.

    Start a reply to this message. Drag the image file in the editing window downloading. Alternatively, you can include text in the response.

    Leave the case open for now.

    Step 2

    Do as in step 1 with this line:

    /Library/LaunchAgents

    The record which can open up will have the same name but is not the same as in step 1. In this step, the folder does not exist.

    Step 3

    Repeat with this line:

    /Library/LaunchDaemons

    This time the file will be called "LaunchDaemons."

    Step 4

    Open Safari preferences window and select the tab 'Extensions'. If the extensions are listed, post a screenshot. If there are no extensions, or if you cannot launch Safari, skip this step.

    Step 5

    If you use Firefox or Chrome browser, open the list of extensions and do as in step 4.

    You may have installed ad-injecting malicious software ("adware").

  • How can we check for backdoor malware software

    My son-in-law fell for a scam of tech support that began with a pop-up message on his ipad; It allowed the scammer talk on access to the ipad by attaching to a pc and installing "logmein". They stop it before paying any $ to the scammer, but they had had access long enough for intsaller everything they wanted anywhere. How find and remove anything the scammery may have installed on the ipad? is it possible that their iphones could also have been compromised if they were connected to the same wifi?

    Good spyware and some other malware villain is not easy to find or remove. The only way to be sure, something they have installed is gone is first to make a backup of your Mac. Especially your personal documents and photos.

    Erase the drive of the Mac and reinstall OS X. Apply updates from Apple for the operating system is up-to-date. Reinstall your applications from third party of their records of origin or digital downloads. Copy manually , back, your personal data.

    Not merge in a backup Time Machine or another type of backup. The purpose of the backup in the first step was to make sure that you do not lose your personal files, only not to restore automatically. Which would bring to any possible malware.

  • Is there a risk to have a Web site, established in Muse and exported to a FTP server, infected with the malware any?

    Hi, a Web site, we have created only in Muse and uploaded to a server FTP was recently blocked by our filter citys due to possible malware/spyware infection. There is no external file any associated with the site, all about the FTP is generated by the Muse.

    We are working on Mac OSX 10.9.5 computers

    Version 2014.2 of the muse

    Nothing in the generated code of Muse will leave you open to something like that. Not hosted on a host of good reputation you will have no problems either. But if your host/server leaves somewhat open then of course all bets are off.

    But again, nothing new in the Muse that will open you to something like that, so if your server is solid, you are well.
