  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!

• Satellite T110-121 - Trojan horses on the installer?

  I recently bought a T110-121. Turned on, set up Windows 7. Uninstalled MacAfee. Deliberately no connection to the internet at all. VET AV. Ran installed AV scan. Showed 2 Trojan horses.

  I don't think that I can reach the screenshots here, but they were the two instances (one in the sys32) and the other in sys64 under the file mfplay.dll Windows directories. VET was not able to clean or delete, or I could, because I don't have the permission from TrustedInstaller to do. VETERINARY said that the Trojan TROJAN horse. WIN32. HOMEPAGE. FW is a pirate of the home page of gravity medium and associated Media Foundation playback by Microsoft Corporation ver 12.0.7600.16385 dated 07/14/2009.

  Has anyone else AV turned up this? And is this normal as Toshiba or Microsoft to distribute Trojan horses with new computers?

  See you soon
  Mike

  Hi mikelawrence,

  > What is normal as Toshiba or Microsoft to distribute Trojan horses with new computers?
  Laughing out loud
  You are a funny guy :D

  Sorry, but to be honest, I'm sure that Toshiba or Microsoft distributes the horses of Trojan or virus with the new product.

  I think that your antivirus software gives you a false alarm and that's it!
  But about the antivirus, you wrote that you have installed "VET AV". I've never heard of this program, maybe that's the problem you have. This could be the Trojan disguised as antivirus program.

  In my opinion, you need to install a reliable antivirus program. AntiVir is a great freeware tool. Alternative, I recommend Kaspersky.

• Satellite M30X: Trojan horse - total Formate with recovery disc?

  Hello

  I had a Trojan horse on my Satellite M30X. My Antivirus deleted, but every time I've been connected to the Internet, it appeared again. Not connected to the Internet it doesn't give me any problems. As I couldn't get rid of him, I backed up all my data and do a fresh install from the recovery disc. As long as the button for LAN wireless is disabled, everything works fine, but just a little while, after I turned on it, I get a blue screen. When I restart my computer with WIFI turned on, it produces a blue screen before Windows is properly loaded, even during installation. I tried restoring 3 times, but it's always the same result.

  1 is it possible, that the Trojan horse destroyed things of the pre installation?
  2. I can't choose to make a formatting during the recovery process. All data are lost, but I feel that's not formate the hard drive correctly, when everything is destroyed. It crushes just stuff?
  3. is there a way to make a good formatting, then install completely new Windows?

  It is not a problem of my WLAN card, internet being no problem under Linux.

  Thank you for your help

  Todier

  Hello!

  If you use the whole HARD disk Toshiba Recovery disk will be formatted so if you have any virus or Trojans on your laptop, they will be also deleted.

  But what BSOD code are you have? Are you sure that's the reason why the virus?
  You have the same problem if you connect a network cable to the laptop?

  Good bye

• unidentified possible Trojan horse

  I think that my computer is infected with some sort of Trojan. I bought this MacBook Air in October and it worked perfectly until today. I tried to read a Web site and page could not finish loading and it kept opening other tabs very suspicious. When I visited perfectly firefox regularly guarded site redirecting them to pages like this:

  

  And there's always a pop up window asking me to download MacKeeper (I didn't download it!). The same thing happens when I use Safari.

  I checked the Add-ons, and I don't know what could cause me (even if I don't know what these modules are Flash and Java). I read that Java can cause Trojans and I installed it recently. But it was earlier this week and I did not notice something different.

  

  Then I not unhooked firefox and installed again, but nothing has changed. I googled and found that trojans and malware can be in the library, and then I found this:

  

  What should I remove without damaging my brand new computer? One of them may be the Trojan horse that I'm looking for? Besides that I also found a local.cfg in Macintosh HD, is that suspicious?

  I've updated to El Capitan earlier this week, and that's all right. A day earlier, I installed Adobe Illustrator and it required me to install Java, I don't like at all about Java. But as I said before this computer started showing this odd behavior today. Yesterday, I tried to download a pdf file from a Web site with a lot of pop ups, that could be the cause. But what can I do? I searched a lot of common trojans and found nothing.

  I have a friend suggested that I should download Malwarebytes and run tests. But is it safe?

  It's a scam jump upward. Do not call or click on anything either that it asks you. If you use Safari, force quit Safari then all by pressing and holding SHIFT restart Safari.

  MalwareBytes is safe.

  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.

• 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!
  Steven

  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!

  Get your installation media, product keys, backup, etc. all together.

  Low level formatting (writing zero or zeros) the hard drive.

  Your installation media to restore the system to factory settings.  (Clean install).

  Continue to use your computer - but get best antivirus (eSet NOD32 AntiVirus - I suggest you not the sequel) and an anti-malware application (I suggest MalwareBytes AntiMalware).

  Why this extreme?  In the end - it's what's going to happen anyway if you ever want to be fully confident in this machine again.
