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.

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.

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.

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.

ClamAV fails to scan for viruses in emails [CLAWS MAIL]

I've recently switched from Thunderbird to Claws Mail and ran into one small, but annoying, problem.
I want to use ClamAV + the clamav extension for claws mail to scan for viruses, however it does seem to have permission problems.
clamd is running, user and group clamav all have the relevant permissions as far as I can tell, however upon scanning my mail, I always end up with the following error:
Scanning error:
/home/username/.claws-mail/mimetmp/0000000e.mimetmp: lstat() failed: Permission denied. ERROR

That is not quite accurate. There are no Mac viruses to be protected against. Snow Leopard includes protection against the few known trojans, provided you download using a program that supports quarantine (the feature that warns you "This application was downloaded, do you want to open it, blah blah").
The whole "defense against viruses" thing on that page refers to the fact that Mac OS X is a difficult target for viruses, due to security features in the OS. It should not be interpreted as the presence of any kind of virus scanner as part of the OS.
Note that I'm not advocating installation of third-party AV software... as you say, it is commonly a lot more trouble than it's worth, especially considering how low its worth actually is. I just think accurate information is very important on this issue.

Suddenly my imac will not open e-mail attachments. It scans for viruses. I hit continue and nothing happens.

Suddenly my imac will not open e-mail attachments. It scans for viruses. When I hit "continue", nothing happens.

The problem most likely is the antivirus application. My recommendation would be following the developers instructions, uninstall the application. Most antivirus applications tend to create more problems than they solve. The best thing you can do for your system is to run Software Update frequently and let Apple's security handle any issues. I'd also strongly recommend you carefully read Thomas Reed's Mac Malware Guide.

How do I run a scan for viruses on a iPad

How do I run a scan for viruses on iPad

You don't. There are no virus scanners because there are no viruses that can affect an unmodified iPad.
The iPad is not a virus prone Windows PC, so doesn't suffer the same daily problems that Windows does.

Error Message: Scanning for Viruses

I uploaded my file on Friday Morning June 25, and I got that error message that my file was being scanned for viruses. Does it take that long? I have some very important files that I need to access, is there any one who can tell me if I can get someone to speed up the process or is this simply a technical issue? Thanks.
Rob

Hi Michelle,
It's unlikely, as it was on my work computer, and I do not work at that firm
anymore, which is the whole reason I wanted to save it. Is there any way a
technician or someone can manually override this error message/cancel the
virus scanning process, or do any sort of similar process so that I can gain
access to it. I don't care if it's not scanned since I created and uploaded
the file, so I know there is nothing harmful on it (our systems at the firm
had an unnecessarily high level of virus protection). I really really need
to get this file or 2 months worth of my work will be gone!
Thanks for your help in advance.

P10 shutting down without bluescreen while scanning for viruses or cleaning

My P10 shuts down when I scan for viruses or cleaning the system. Since I bought the notebook it works absolutely perfect. But 2 days ago I recognized this For normal work e.g. word, excel, surfing the net and so on, nothing happens, everything works but if I begin to scan, XP shuts down. It just turns off as if you unplug it from circuit!!! Can somebody help me, wrong drivers?, false hardware? I dont know how to solve the problem!!!! Which information do you need???

Hi Kay,
This sounds like a classic case of over-heating. Especially if you notice increased fan activity just prior to the notebook shutting down.
Try cleaning the dust and debris from the CPU heat-sink. You will find lots of posts in this forum describing ways of doing this. My personla favorite is to use a vacuum cleaner hose against the air intake grilles.
Also, it is worth making sure that the air intake grilles are not being blocked, and that sufficient air can get into the notebook to cool it properly. Don't stand your notebook on a soft surface or carpet since this will allow more dust to be sucked in.

Scanning for viruses on Mac

I'm interested in scanning for viruses, not to protect my Mac but to avoid sending them to others. I've read a little about ClamXav and would like to hear from those of you who have used it. I don't want to run it continuously, but instead do a periodic system scan. Is it suitable to use like this? Any tips, benefits, or drawbacks you can tell me about? Thanks.

Hello ha:
I am certainly not trying to dissuade you from helping others (I try to do that myself). However, anyone who runs a Windows box without A/V software, firewall(s), moats, and boiling oil on the ramparts is asking for it. The only way you would send a virus out would be an E-mail. If you open a web site that has a Windows virus it will not harm your Mac or go anywhere else - unless you download it and then E-mail it.
A/V software is, IMHO, a complete waste of time and resources for anyone running a Mac with OSX.
Sorry for the sermon, but I cannot imagine a Windows user without robust A/V software. In my former professional life, we ran Wintel boxes and had everything (including barbed wire) to pick off viruses. My IT people used to produce a report detailing how many viruses they intercepted and deactivated.

While using Firefox, a site popped up and said it was Firefox scanning for viruses. It then said I had dangerous viruses and should download a security program. Is this for real? The site was update32.escmce.ce.ms

While using Firefox, a site popped up and said it was Firefox scanning for viruses. It then said I had dangerous viruses and should download a security program. Is this for real? The site was update32.escmce.ce.ms I googled this site and it does not exist. Now, I am worried about the security on my computer.

If you're running under Windows, I suggest you download and install Microsoft's Security Essentials. It protects against these types of attacks and tends to find stuff that other anti-virus scanners don't find. You're system could be infected because of that bogus, evil anti-virus scan. Install and run the software while in safe mode.

Viruses/Spyware/Malware/Trojans etc. Protection

I am new to Macs but am pretty tech savvy. Do I really need a virus scanner? Do I need spyware protection? I use ClamXav for virus scanning. But it seems pretty unsecure and not reliable. Are there any other free virus scanners/anti-spyware software? Also is the OS X firewall secure enough, I know that it doesn't stop outgoing connections? How do you deal with these problems? Do you use any protection? Thanks.
iMac Core Duo/iPod Photo 30 gig/Windows Knowledge Mac OS X (10.4.8) 17 inch

Hi.
I'm surprised that you find ClamXav "…pretty unsecure and not reliable". It is the usual recommendation for free virus scanning on these boards. In what way do you find it so? Has it failed to pick up a Mac virus that you know is on your system? Unlikely as there are no true Mac viruses 'in the wild'.
The OS X firewall is generally considered to be 'industry strength' but can be fine tuned with tools such as Snort in conjunction with Henwen, or Flying Buttress.
As regards outgoing connections, Little Snitch is a lovely little shareware application. The usual comment on Little Snitch is that it does one thing and does it well.
You might like to take a look at Dr Smoke's Detecting and avoiding malware and spyware, &/or, if you've got half a day to spare, put 'virus' into the search box over there------->>>>
Reams of comments have been posted and I'm not going to reopen the argument now as it's all been said before, but just so you know which side of the camp I'm on, I use no AV software. I have the Mac and router FWs on, I use Little Snitch and common sense.
Have fun,
Adrian

Ways to scan for viruses on macs?

I want to scan and check for viruses.

1. This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets (see below.)
It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
3. Starting with OS X 10.7.5, there has been another layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't actually been tested by Apple (unless it comes from the Mac App Store), but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. For most practical purposes, applications recognized by Gatekeeper as signed can be considered safe.
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
It can easily be disabled or overridden by the user.
A malware attacker could get control of a code-signing certificate under false pretenses, or could find some other way to evade Apple's controls.
4. Beyond XProtect and Gatekeeper, there’s no benefit, in most cases, from any other automated protection against malware. The first and best line of defense is always your own intelligence. All known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
That means, in practice, that you never use software that comes from an untrustworthy source. How do you know whether a source is trustworthy?
Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe.
5. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style "virus" affecting OS X. Merely loading a page with malicious Java content could be harmful. Fortunately, Java on the Web is mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other inessential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers. In Safari, this is done by unchecking the box marked Enable Java in the Security tab of the preferences dialog.
Currently, when you install the Apple-supplied Java runtime (but not the Oracle runtime), a "Malware Removal Tool" (MRT) is also installed. MRT runs automatically in the background and appears to scan your files for installed malware that may have evaded XProtect. Like XProtect, MRT is probably effective against known attacks, but not against unknown attacks. There is no user interface to MRT.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a specific task, enable Java only when needed for the task and disable it immediately when done. Close all other browser windows and tabs, and don't visit any other sites while Java is active. Never enable Java on a public web page that carries third-party advertising. Use it, when necessary, only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Follow the above guidelines, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself from malware.
6. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. If you need to be able to detect Windows malware in your files, use the free software ClamXav — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
7. ClamXav doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
ClamXav is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
ClamXav may be able to tell you which particular virus or trojan it is, but do you care? In practice, there's seldom a reason to use ClamXav unless a network administrator requires you to run an anti-virus application.
8. The greatest harm done by anti-virus software, in my opinion, is in its effect on human behavior. It does little or nothing to protect people from emerging threats, but they get a false sense of security from it, and then they may behave in ways that expose them to higher risk. Nothing can lessen the need for safe computing practices.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.

Browser Virus Malware Adware etc. HELP!

I have been trying for 3 days to kick this absurd problem off of my Macbook Pro. It feels like I have a virus/malware/adware situation that is making me feel like I'm back on a PC (UGHHHHH).
BEFORE THE PROBLEM:
I kept getting "scratchdisk" or "startup disk" is full notices so I could not download the new OS
I started searching the web for solutions
I started removing all unneeded files
I used Clean My Mac to remove unwanted/unneeded files
I downloaded OS X 10.9.5
THE PROBLEM:
The following things occur when I attempt to use any of the 3 browsers: Google Chrome, Safari, Firefox:
pop up windows appear ALL over the place
Pop up windows block my ability to use the intended web page
tabs automatically open for Wix, Mackeeper, Credit Check websites etc. (It's infuriating!)
Sites I am attempting to use fail to respond
ACTIONS TAKEN:
run Clean My Mac (nada)
delete all cookies (nada)
trash or uninstall any/all unknown apps/programs
uninstall Google Chrome
uninstall Firefox
reset Safari
some terminal exercise from an Apple forum (did...nada)
RESOLVE:
NOTHING seems to be working...I'm about to launch my computer out the window... HELP!?

There is no need to download anything to solve this problem.
A.
You may have installed the "VSearch" trojan. Remove it as follows.
Malware is always changing to get around the defenses against it. These instructions are valid as of now, as far as I know. They won't necessarily be valid in the future. Anyone finding this comment a few days or more after it was posted should look for more recent discussions or start a new one.
Back up all data before proceeding.
Step 1
From the Safari menu bar, select
          Safari ▹ Preferences... ▹ Extensions
Uninstall any extensions you don't know you need, including any that have the word "Spigot," "Trovi," or "Conduit" in the description. If in doubt, uninstall all extensions. Do the equivalent for the Firefox and Chrome browsers, if you use either of those.
Reset the home page and default search engine in all the browsers, if it was changed.
Step 2
Triple-click anywhere in the line below on this page to select it:
/Library/LaunchAgents/com.vsearch.agent.plist
Right-click or control-click the line and select
          Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item named "com.vsearch.agent.plist" selected. Drag the selected item to the Trash. You may be prompted for your administrator login password.
Repeat with each of these lines:
/Library/LaunchDaemons/com.vsearch.daemon.plist
/Library/LaunchDaemons/com.vsearch.helper.plist
/Library/LaunchDaemons/Jack.plist
Restart the computer and empty the Trash. Then delete the following items in the same way:
/Library/Application Support/VSearch
/Library/PrivilegedHelperTools/Jack
/System/Library/Frameworks/VSearch.framework
~/Library/Internet Plug-Ins/ConduitNPAPIPlugin.plugin
Some of these items may be absent, in which case you'll get a message that the file can't be found. Skip that item and go on to the next one.
The problem may have started when you downloaded and ran an application called "MPlayerX." That's the name of a legitimate free movie player, but the name is also used fraudulently to distribute VSearch. If there is an item with that name in the Applications folder, delete it, and if you wish, replace it with the genuine article from mplayerx.org.
This trojan is often found on illegal websites that traffic in pirated content such as movies. 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.
You may be wondering why you didn't get a warning from Gatekeeper about installing software from an unknown developer, as you should have. The reason is that the Internet criminal behind VSearch has a codesigning certificate issued by Apple, which causes Gatekeeper to give the installer a pass. Apple could revoke the certificate, but as of this writing has not done so, even though it's aware of the problem. This failure of oversight has compromised both Gatekeeper and the Developer ID program. You can't rely on Gatekeeper alone to protect you from harmful software.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
          Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
B.
Remove "MacKeeper" as follows. First, back up all data.
"MacKeeper" is a scam with only one useful feature: it deletes itself.
Note: These instructions apply to the version of the product that I downloaded and tested in early 2012. I can't be sure that they apply to other versions.
If you have incompletely removed MacKeeper—for example, by dragging the application to the Trash and immediately emptying—then you'll have to reinstall it and start over.
IMPORTANT: "MacKeeper" has what the developer calls an “encryption” feature. In my tests, I didn't try to verify what this feature really does. If you used it to “encrypt” any of your files, “decrypt” them before you uninstall, or (preferably) restore the files from backups made before they were “encrypted.” As the developer is not trustworthy, you should assume that the "decrypted" files are corrupt unless proven otherwise.
In the Finder, select
          Go ▹ Applications
from the menu bar, or press the key combination shift-command-A. The "MacKeeper" application is in the folder that opens. Quit it if it's running, then drag it to the Trash. You'll be prompted for your login password. Click the Uninstall MacKeeper button in the dialog that appears. All the other functional components of the software will be deleted. Restart the computer and empty the Trash.
☞ Quit MacKeeper before dragging it to the Trash.
☞ Let MacKeeper delete its other components before you empty the Trash.
☞ Don't try to drag the MacKeeper Dock icon to the Trash.
