That my Mac has a Trojan horse?

Similar Questions

• I think my Mac has a Trojan horse.  How to remove?

  Sometimes when I click on a link on Safari opens a new tab the same and the former tab becomes a sort of announcement (Mac clean, zipcloud, etc.).  Can I have downloaded Adobe Flash Player on a bad site.  My search engine site which is usually Google changes also to something else.

  I am running OSX 10.11.12

  How can I solve this problem?

  So you know in the future, never download anything from anywhere other than the App Store OR Web site.  Who will help protect you from downloading something that has been bundled with malware/adware.  You can download Adobe Flash Player here.

  For addressing what you do deal with now, I suggest you download Malwarebytes Anti-Malware for Mac.  It was developed by a trust post it here, and it's a safe option for you can use to get rid of what is infect your system.  Install it and let it run, following all the instructions it gives you.  Restart your computer, and you should be set to rights.  In the future, consider my previous opinion - download on the Web site or on the App Store.

• Update the BIOS has a Trojan horse

  I have been a problem with my computer and finally was the wick of the ball and update to the latest BIOS version when I was arrested by the McAfee anti-virus.  I have a HP Pavilion model number a6257c.  At present, it has BIOS rev 5.21.  The most recent BIOS rev on the HP website is 5.23 (for this model of computer).  After you download the sp37378.exe file, I double clicked it.  In these conditions, frustrated by the other problem I had (which I'll detail in the portage on the other), I forgot to disable the McAfee real-time analysis.  Just before I was on the click the OK button to continue with the upgrade of the BIOS, a window of McAfee popped-up informing me that it has detected a Trojan horse on my system.  Knowing that the only thing I did was upgrading the BIOS, I abandoned the upgrade of BIOS to investigate the message from McAfee.  Of course, check the McAfee log, he showed that in the flash.exe (created when I double click on the sp37378.exe file) contained a "Trojan" called "New Maleware.jj" following the links displayed in the journal of McAfee, I found this web page: http://vil.nai.com/vil/content/v_153095.htm.  It is listed as a threat of "Low".

  So now finally my question, is it planned in the upgrade of the HP BIOS?

  I downloaded the BIOS file and scanned with AVG - no viruses. I extracted the temp files and scanned the files checked - no viruses.

• Norton says thunderbird is dangerous to download and used to let me do it. Another security program said it has a Trojan horse and won't let me download it.

  I used Thunderbird for at least 10 years and it downloaded many times on different computers. After a computer crash, I'm trying to download it, but 2 programs of security would not let me do. I just downloaded Firefox without problem. I see that others have had this problem, but have so far not found a solution.

• In XP Trojan horse Virus problems

  Two weeks ago, my computer became infected with a trojan virus.  I started having problems with hidden files to become and then has to connect to my AT & T Yahoo email account.  A tech AT & T ran a sort of diary on my computer and said that the problem was a Trojan horse.  I then reinstalled my OS (XP SP3) but soon had the same problem with the files become hidden.  These have been discovered when I ran my Avira anti-virus free progr.  Since then, I have probably reinstalled my OS 4 times more and almost immediately to have the same problem with hidden files.  When you run Avira, I would get the following error message: "one or more hidden objects that indicate a hidden virus or unwanted program found."  Because of this message, Avira would never execute the search.

  In addition to Avira, I also run Windows Defender, Malware Anti-Malware and Super Anti-Virus Free Edition.  I usually run 2 of these programs every day.  When I reinstall my operating system, I always install the same software (most who are on an external hard drive) I have always used.  File types that are hidden are: Application Data models, send to, the local settings and Config.Msi.  Yesterday, I tried to show all the files I could find (this time there were about 12), but when I ran Avira I got the same error message indicating that there is more hidden files.

  Read the other questions previously posted and answered about a trojan virus infect a XP system, I uninstalled Avira and installed Windows Security Essentials.  However, no threats were detected during a scan.  I also downloaded Vipre Internet Security and just now completed a deep analysis, even when no threats were detected.

  I have to admit that I'm a little computer illiterate, but is there anything else I could try to fix this other than to reinstall my operating system once more?  Is there a log I could run to determine what program this is what keeps infecting my computer?  Also, should I break down and buy an anti-virus program rather than use a free?

  Help! Help! Help!

  A big thank you to all who gave advice.  Before I got your answers, I decided to reinstall my operating system once more as I have had problems with a program that ran for many years.  Patience isn't one of my virtues.  After reinstalling all my programs, I ran Avira and again received the following error message: "one or more hidden objects that indicate a hidden virus or unwanted program found."

  Daavee mentioned in his reply that the file types, I mentioned in my original question are supposed to be hidden.  However, I wonder why Avira thinks that these hidden files are potential viruses.  Also, since I have never hidden their in the first place, how they became hidden?  I always show everybody I find, but somehow they always becomes hidden again.  What causes this?

  I took the advice of AndreasAnaya and uninstalled all my programs except Defender antivirus and installed Avast.  The anti-spyware and anti-malware the same as antivirus?  I do not, but uninstalled Super Anti-Spyware and Malware Anti-Malware as Avira before installing Avast.

  I just ran Avast and no virus was found.  However, he found two errors; "Has reached the end of the file."  I don't know what that means.  I tried to remove chest as instructed by Andreas but when I clicked on the chest, nothing was there.

  If all goes well, by deleting my previous operating system before installing it again (as indicated by Andreas), a virus has been removed.  Once again, thank you for all the advice!  I hope that all my problems were solved!

  Hello

  If you need search malware here's my recommendations - they will allow you to
  scrutiny and the withdrawal without ending up with a load of spyware programs running
  resident who can cause as many questions as the malware and may be harder to detect as
  the cause.

  No one program cannot be used to detect and remove any malware. Added that often easy
  to detect malicious software often comes with a much harder to detect and remove the payload. Then
  its best to be thorough than paying the high price later now too. Check with them to one
  extreme overkill point and then run the cleaning only when you are sure that the system is clean.

  The methods below are for Windows 7 - Vista is very similar - for XP using RUN instead of
  Start - Search,.

  It can be made repeatedly in Mode safe - F8 tap that you start, however, you must also run
  the regular windows when you can.

  TDSSKiller.exe. - Download the desktop - so go ahead and right-click on it - RUN AS ADMIN
  It will display all the infections in the report after you run - if it will not run changed the name of
  TDSSKiller.exe to tdsskiller.com. If she finds something or not does not mean that you should not
  check with the other methods below.

• Trojan horse on my mac!

  I ran the Bitdefender anti-virus on my MacBook Pro and it is Trojan.JS.RAN and I was surprised that I'm always careful what to download and install!

  I removed it, but now I'm not sure that this Trojan horse on my computer? and what should I do to make sure that there are more malware/virus on my computer? and what is the best antivirus/antimalware should I use in the future?

  NB: I've always updated my Mac every time that one updates see the place!

• I tried to post a coupon on xianet and my computer has been taken over by a Trojan horse.

  I tried to post a coupon on xianet and my computer has been taken over by a Trojan horse. My report says: Win32/fakeSysDef. He directs me to a data recovery site that charges $75 to solve the problem. No idea how to do to remove the Trojan horse?

  Microsoft support addressed my problem and Javier took control of it and solved the problem.

  It has been pretty smooth how I got the Trojan horse. When I tried to display a coupon, a dialog box came asking if I wanted to download a software. I clicked 'Cancel' and this is meant to 'run '. That's when all this started.

  Thanks for help.
