Do I have a virus or Trojan malware on my MacBook Pro?

I downloaded a faulty mp3 file from the internet which I think infected my computer with either a virus or Trojan malware. It took over my computer and disallowed me from accessing any applications. I clicked on Finder, for example, and a window would pop up saying, "Application not found," with a number after it. I rebooted by computer and was able to log back in using Safe Mode. Here, I deleted the file I had downloaded, or so I thought, by dragging it to the trash and emptying it. However, my computer is acting bizarre and barely functions. I am unable to use DVD Player, it says, "There was an initialization error" with code -70017. My volume is unaccessible, there is a circle with a slash through it when I try to use it. Itunes will not work, Iphoto keeps crashing and will not open, and my internet browser is extremely slow and will not play video.
I have downloaded and installed Sophoes Anti-Virus and MacScan in an attempt to rid my computer of the virus but it did not seem to do anything.
Suggestions as to how to fix this problem would be greatly appreciated.

This is not the work of a virus, or any other kind of malware. What it sounds like is a very badly corrupt hard drive causing all manner of corruption in your various system components and applications. You probably need to erase your hard drive and reinstall the system from scratch, as ds store has said.
If you actually had malware, Sophos would find it. If Sophos found nothing, there was almost certainly nothing to find. If something like Sophos ever should find malware, unless the malware has "OSX" or "MacOS" in the name, it probably isn't Mac malware and thus isn't something you need to worry about (other than not passing it on to other people).
MacScan is junk. It serves no useful purpose. See:

Can you get an virus or trojaner through the connection-cable (PC) from your iPod touch?

I had an trojaner on my PC earlier and my iPod touch 4G was connected to my computer. Is it possible for the trojaner or viruses in general to make their way through the connection cable or something? If a photo or something wasn't infected. I mean sync-wise, etc.

It would be very difficult for a virus or trojan to get from the iPod to your PC via USB. Attaching a virus to any media file such as a photo or music track is very, very difficult, and all known exploits that would do this were blocked a long time ago. Attaching a trojan would not be possible. Unless there's a new exploit I haven't heard of, only if a trojan program was attached to an email and from there transferred to an app that could then be synced to your computer would it be possible malware come from your iPod. I think that rather unlikely and that your trojan got into your PC from some other source.
Regards.

Virus, a Trojan, or something else?

Virus, Trojan, something else?
My computer sent an email to about 50 people yesterday with an attached zip file. The email had no subject, and the zip file contained about 20GB worth of documents off my computer. Most of the recipients are not in my addressbook, but all were people whom I have emailed before. The name of the attachment ends with documents-1-1.mailhold.zip.
Does anyone know what cause be email to get sent? Was this a virus, a Trojan, or something else?
Thanks for the help.

Adobe Flash 12 for windows 7 : Seems infected by a Virus or Trojan

Adobe 12 seems infected with a virus. After installing Adobe Flash 12 my computer is controlled by some program that tries to immediately connect to the internet and play VERY IRRITATING sounds that sound like someone is changing a radio station constantly. Sounds from the NEWS, Music and vulgar content material is streamed from the internet to my computer even though I have not connected to the internet. This virus on Adobe immediately connects to the internet if I have a connection. When I select my speaker and mixer control I see "Unknown Device" as the source of the sounds from the internet.
I can MUTE the application in the mixer but the malicious program continues to run.
My antimalware and antivirus software cannot eliminate this computer virus because it is part of the Adobe Flash 12 software that was installed.
The only way I can eliminate the problem is to UNINSTALL the Adobe Flash 12.
Does anyone know why Adobe Flash 12 seems to be infected with a computer virus or trojan?
I recommend everyone avoid using Adobe software as they seem to have a malicious computer virus embedded in their software.
Continual use of Adobe Flash 12 can result in others invading your computer and the loss of private information so I suggest everyone stop using Adobe Flash 12 until it is cleaned of the virus.
Do you want your computer to constantly dial up the internet without your permission and transfer data to unknown persons?

Mike,
After I installed the software you recommended there was more to the story from my last email.
My computer was now much worse and out of control so I was forced to turn off my machine and cold restart it.
The computer would not restart at all. It tried to start windows but instead it ran in an infinite loop. I would see the Dell screen and then the Windows would pop up saying it was restarting and then it would go bland and the Dell Screen would pop up and then the Windows restart screen again and again and again.
I shut it down and tried to start it in Safe Mode. That wouldn't work either. It was stuck in a loop just like in Normal mode.
So I had to shut down and do a System Restore to a selected REstore point.
That worked and now my computer is as it was before but it still has the virus and if I try to use Adobe Flash it will again connect to internet and play irritating sounds.
So what could have fixed this problem? Should I have quarantined the 4 offending files or just the DCOM file?
Why did your software nearly destroy my computer's ability to restart?
What do you suggest?

Safari redirect hijack - may have iOS5 virus or trojan

This morning, while clicking on a link on a website, I was redirected to a **** site. Not so unusual, eh?
Except this was on my iPhone 4s, running iOS 5 and Safari, and the same link is good on my Mac desktops.
Clearing data, history, caches, and a reboot does NOT fix the problem.
It appears that there is a virus or trojan on my iPhone. Any ideas?

I also have this exact problem
I don't know how to resolve its I am not an expert in apple devices
If you did eventually resolve this issue, can you please post e solution up here for usto try it too

Virus / keylogger / trojan / adware on a Mac?

How do i find and remove virus / keylogger / trojan / adware on a Mac?

Helpful Links Regarding Malware Problems
If you are having an immediate problem with ads popping up see The Safe Mac » Adware Removal Guide, AdwareMedic, or Remove unwanted adware that displays pop-up ads and graphics on your Mac - Apple Support.
Open Safari, select Preferences from the Safari menu. Click on Extensions icon in the toolbar. Disable all Extensions. If this stops your problem, then re-enable them one by one until the problem returns. Now remove that extension as it is causing the problem.
The following comes from user stevejobsfan0123. I have made minor changes to adapt to this presentation.
Fix Some Browser Pop-ups That Take Over Safari.
Common pop-ups include a message saying the government has seized your computer and you must pay to have it released (often called "Moneypak"), or a phony message saying that your computer has been infected, and you need to call a tech support number (sometimes claiming to be Apple) to get it resolved. First, understand that these pop-ups are not caused by a virus and your computer has not been affected. This "hijack" is limited to your web browser. Also understand that these messages are scams, so do not pay any money, call the listed number, or provide any personal information. This article will outline the solution to dismiss the pop-up.
Quit Safari
Usually, these pop-ups will not go away by either clicking "OK" or "Cancel." Furthermore, several menus in the menu bar may become disabled and show in gray, including the option to quit Safari. You will likely have to force quit Safari. To do this, press Command + option + esc, select Safari, and press Force Quit.
Relaunch Safari
If you relaunch Safari, the page will reopen. To prevent this from happening, hold down the 'Shift' key while opening Safari. This will prevent windows from the last time Safari was running from reopening.
This will not work in all cases. The shift key must be held at the right time, and in some cases, even if done correctly, the window reappears. In these circumstances, after force quitting Safari, turn off Wi-Fi or disconnect Ethernet, depending on how you connect to the Internet. Then relaunch Safari normally. It will try to reload the malicious webpage, but without a connection, it won't be able to. Navigate away from that page by entering a different URL, i.e. www.apple.com, and trying to load it. Now you can reconnect to the Internet, and the page you entered will appear rather than the malicious one.

TS3274 Can an iPad get a virus or Trojan infection?

I'm just wondering if an iPad can get infected with viruses?

No, there are no known virus or trojan for a non jailbroken device.
If it is jailbroken then yes.

Virus - Gen:Trojan:Heur.LP.Ev5@auW5fMI

After performing an Adobe Reader update my Bitdefender software indicated that my system was infected with a virus "Gen:Trojan:Heur.LP.Ev5@auW5fMI". WOuld appreciate any advice as to how this can be removed.

Several searches in the McAfee database (full given name, and different parts of it) gave me no results. And a Google search only gave the two messages in this thread.

Mcfee Software has detected viruses and trojans

Bought laptop 2 days ago and installed McFee software (as recommended). McFee scan says computer is virus free and no problems found.
Problem is I have various warnings on pop ups saying system has up to 23 viruses and trojans detected "system is about to crash".
Anyone know what is going on?

> Bought laptop 2 days ago and installed McFee software (as recommended).
Just out of curiosity, who recommends you to install McFee?
I dont know what is wrong there but maybe this McFee has detected some Toshiba specific stuff and has identified them as virus. I dont know what is listed as virus.
Contact McFee manufacturer and ask for help. Toshiba doesnt support this third part software.

JAVA OPENSTR.A - VIRUS OR TROJAN???

Hi There,
I am a knowledgable home computer user, but I do not know anything about programming or in depth stuff.
Trend Micro's "House Call" virus scanner found the following file and reported it as a virus.
C:\Documents and Settings\Ned\Application Data\Sun\Java\Deployment\cache\javapi\v1.0\jar\javainstaller.jar-3c936701-5768e0d4.zip javainstaller\InstallerApplet.class
I wonder if this file is perhaps a valid Sun Java file, but it has a "signature" similar to that of a virus or Trojan and hence was reported by House Call as a virus.
Could you please advise me?
Thanks very much for your help.
Sincerely,
Guiterdas.

The same here.
Norton Anti Virus autoprotect suddenly reported the presence of the virus Trojan.ByteVerify in the InstallerApplet.class file in some temp directory.
The scanner found the same file in my docs and settings. Saved a copy in case it's a hoax, but what's up?

JAVA Virus Found - Trojan Horse (URGENT)

I used NAVCE to perform a virus scan on my system and it reported a virus found, trojan horse. Here's the report:
Scan type: Manual Scan
Event: Virus Found!
Virus name: Trojan Horse
File: C:\Documents and Settings\Administrator\Application Data\Sun\Java\Deployment\cache\javapi\v1.0\file\Dummy.class-1012b178-3c3750b0.class
Location: Quarantine
Computer: SLEEP
User: Administrator
Action taken: Clean failed : Quarantine succeeded :
Date found: Fri Oct 24 00:51:03 2003
The folder that the trojan horse resides is a hidden file. Can anyone tell me what's happening? Preferably someone from Sun would like to explain?

forget it. You got that virus from some webpage. Besides, it shouldn't activate unless some moron has changed the defaults on yout windows comp. just delete it, don't lose yer sleep.

Viruses, malware, trojans, etc.

I have an MPB, OSX 10.5.8 and a 16.5 year old son. I was able to resolve the kernel panic problem, but only because I had access to an external drive version of an install disc with which I could fire up Disk Utility, which then made repairs. I had been able to reboot from neither an onboard install disc nor an internal TechTool eDrive.
Suspicious, I installed and ran ClamXav anti-virus tool and found two items:
hottiestar_installer.exe decsribed as Trojan.Inject-3034, and
useGoingBook.class-73a68686-5131a64d.class described as Trojan.Downloader.Java.ClassLoader-1 .
ClamXav placed the two in a folder and then I trashed them both. Am I done? Is it safe? I know so little about how these things operate and what they do. It seems like I've killed the messengers, but have I destroyed the messages?
Is it more likely that these were picked up from friends with infected Windows machines than from direct downloading to the MPB?
Thank you.

I am looking at buying a MBP. My brother goes to ITT and he said that they are talking about the rise of mac viruses. Is this something I should consider when buying, like should I pay for the anti-virus or are the types of viruses that they were talking about not something to worry about?
Welcome to Apple's discussion groups.
There really are no Mac viruses in the traditional sense. There are Mac trojans, which can be avoided by actions such as declining offers to install "codecs" that claim to allow viewing of questionable content.
Safari and OS X have a certain amount of malware protection already built in. If you really want to install anti-virus software on a Mac, consider ClamXav: http://www.clamxav.com/
One more piece of advice: If you're looking for advice, start your own thread instead of attaching your question to a thread already marked as "answered", as those threads receive a lot less attention than unanswered threads.

Sophos found a virus and trojan in Time Machine backup. What to do?

I ran Sophos Anti-Virus last night and it found two Windows viruses (one of them is Troj/20120158-P, a trojan, the other is Mal/TibsPk-A, a "malicious behavior" type). Both are attachments on emails that are in Time Machine only. Obviously I'm not worried about them affecting the Mac, but I'd like to avoid accidentally sending them to some poor victim who's using Windows.
I can track down the files by going into the drive and manually deleting them, but would that mess up Time Machine? Is there a better solution?
Thanks!

You should never poke around in your Time Machine backups to delete files in the Finder. That can damage the backups. You also should make sure that Sophos does not attempt to quarantine files from your Time Machine backup. In fact, you probably should ensure that Sophos (and any other anti-virus software) never touches your Time Machine backups in any way, even just for scanning. Let Sophos do its job of keeping the malware off your main hard drive, and leave Time Machine alone to back up freely without interference.
As for how to handle those e-mail messages in your backups, I would just leave them. They're not doing any harm there, and there's almost no chance that a chain of circumstances would arise that would result in you restoring those messages and then sending them to a Windows user. They will eventually be removed from your backups, when the backup drive fills up and Time Machine has to start removing the oldest deleted files from the backup to make room for new stuff.

Scanning for virus/malware/trojans, etc?

My online security has been seriously compromised in the past two weeks. It started out with my email account being hacked, and a spam message sent to everyone in my contact list. Now all of my domain names were hacked (most likely via my FTP software) and something installed malicious code into all of my websites that install a trojan on any unsuspecting visitor.
I believe a computer in this house is (or was) acting as the router for all internet traffic and is sniffing passwords. At least, that's the only logical thing I can think of.
I'm afraid to find out what's next, but I need to find the root of this problem and GET RID OF IT. We have a PC in the house, which I was hoping was the culprit, I completely wiped that hard drive clean and re-installed the OS, so that checks out now. And the problems are still occurring. The email hack happened before i wiped the PC, and the attack on my websites happened after. Or, at least, I NOTICED it after. It could have happened at the same time for all I know. But I want to be ABSOLUTELY sure that there's NOTHING on Macs that can be doing any damage.
I ran ClamXav and MacScan on all 3 of my macs. All scans come up clean. Are there any other things I can do to check my system? I want to be completely sure. I don't want to have to format and re-install Leopard on these computers if possible.
Thank you.

You said you only used gmail from the web interface. Is your contact list online as well?

Why would your FTP software be to blame? It is possible that some 3rd party could have sniffed your password if you were using an unsecure protocol, which standard FTP certainly is.
I believe a computer in this house is (or was) acting as the router for all internet traffic and is sniffing passwords. At least, that's the only logical thing I can think of.
That's not very logical. I doubt that the PC could "take over" routing. It could have been completely compromised and that would compromise any password used on that machine or shared with any other account anywhere else. Your actual broadband router could have been hacked. That isn't likely or common, but it is possible.

OK - there you go - get rid of it.
And the problems are still occurring.
Have you changed all of your passwords via secure connections?
The email hack happened before i wiped the PC, and the attack on my websites happened after.
Websites are a different issue. If your passwords were compromised, all bets are off. Still, you have to be careful with websites. If you use things like WordPress and don't keep them constantly updated with security patches, your website can easily be hacked.
But I want to be ABSOLUTELY sure that there's NOTHING on Macs that can be doing any damage.
I ran ClamXav and MacScan on all 3 of my macs.
The Macs are fine. That is the only part you don't have to worry about. There are no viruses to infect them, but you still need to change their passwords. Once they have passwords, there is no need to hack. Just log in.

Possible_otorun6 virus or trojan infected file?

When I plug my ipod into my computer my MicroTrend internet security says that the G/: drive has a virus, trojan, or infected file. It is listed as possible_otorun6, and the file is named G\:autorun.inf. How can I remove this or can I? Should I worry about it since nothing seems to be wrong or affected.
Thanks toddrj63

Unless you are using your iPod as a disk drive and have copied an application to it, then the virus is not on your iPod. Even if it is it will not impact the operation of the iPod.
What other USB device are connected to this computer?
