Virus detection

we have multiple engines running in forefront for realtime scan on hub transport.
Only there is still one type of email with a pdf whihc is constantly quarantined
The pdf file contains a java script, and the Norman Engine detect this pdf file as a virus (pdf/Obfuscated.JS)
I cannot find a way in forefront to bypass this type of file for realtime scanning.
This PDF file is not detected as virus by McAfee, or our cloud email security solution.

Hi，
You need first to confirm if the virus has been written into MS database, you can verify that via the link below:

Directory Damage, what can be used for Disk Repair and Virus Detection?

Hi,
My eMac is acting up. Yesterday I started getting these messages that I needed to restart my computer (message was in a brown box window with an icon of a start up button in background).
I did the disk repair using Start up CD and it came back with "invalid key......." or something like that, and when I tried to repair it, it tried to repair the B-Tree's but then said it could not repair the problem.
I have Diskwarrior 3.03 Build 39, on a CD and on my FW Ext HD, which has a clone of my Mac HD.
Diskwarrior could not produce a graph of Mac HD because the directory was damaged. When I did a rebuild it hung on step 9 comparing directories, said there was 7 million + tests. ( I let it hang on step 9 for 15 hrs. to see if maybe it was just taking a long time due to corrupt directory). I finally clicked on Skip and got to the report page. I could do a preview, but the replace button is greyed out. When I was comparing the sizes of each folder, in both preview and original, I got a can not calculate error message on a few of them. The size of Mac HD in preview compared to the one in Original was different by 4 gbs. A week ago I repaired the Mac HD and did a Diskwarrior directory repair on all my HD's.
Before I do any reformatting of HD or other drastic measures, I was wondering what is safe to use for disk repair and virus detection. I know there is Norton System Works 3.0, Norton AntiVirus and TechTool, are these the only ones? Are these safe to use? Are there any other programs that can repair directory damage?
Thank you in advance,
Deb

The long-standing rule of thimb has been that if Disk Warrior can't repair a mungled disk directory, then you're looking at reformatting or replacing the hard drive. Since this is a week-old hard drive, I'd suspect the replacement hard drive is itself bad. It might save you grief in the long run to contact the vendor who sold you the drive and inquire about their warrenty. You might want to first run the file system check utility fsck as described in Using Disk Utility and fsck
Directory repair and antivirus protection are different critters. Norton AV is mostly safe (if you don't mind it's track record of false positives) and is used by the IT department at the lab where I work. Norton SystemWorks, AKA Disk Doctor Kervorkian, is most assuredly NOT safe. For every poster reporting something nice about it, you'll find at least 2 dozen cursing it. It has a known track record of detecting problems no other utility finds and of "repairing" drives such that nothing can then read or repair the drive short of low-level reformatting (and occasionally even that fails).
Tech Tool Pro 4 has a good reputation, as does Drive Genius. Tiger OS X 10.4.2 and later include a version of Disk Utility that can for the first time also make effective B-tree and keys out of order and overlapped extent repairs. Still, my personal gut feeling is that if Disk Warrior is choking on the hard drive, you're looking at reformatring while zeros the drive (zeroing should detect and map out bad physical secotrs).
You can also refer to Disk First Aid: What to do when it finds an error and to Handling "overlapped extent allocation" errors reported by Disk Utility or fsck

Virus Detected (403), Your file could not be uploaded because it contains a virus.

From a Windows 7 Ultimate PC I tried to upload a PDF portfolio containing 35 PDFs. The upload failed with the message "Virus Detected (403), Your file could not be uploaded because it contains a virus."
It is highly unlikely that this PDF portfolio or its 35 PDFs contain a virus. It passed a scan by Microsoft Security Essentials. Any suggestions?
Bill

Hello,
I've got the same 403 error when I want to upload a ebook (purchased on peachpit, see this url for ebook), but when I scan it (windows 8 / avast) no virus found.

I am usiing Kaspersky Internet protection. I keep getting a 403 error Virus Detected on just one of the files that I am trying to convert. What do I need to do.

I am getting a message 403 that the file that I am trying to convert has a virus. I use Kaspersky virus detection and I ran it on just that file. I have converted another file with on problems. What do I need to do?

What is your Windows version? 32-bit or 64-bit?
Internet Explorer: you must use the 32-bit version, regardless of your OS version.
What is the exact error you get, and what are you doing when you get that error?

Mail server rejected message: spam or virus detected (#5.3.0)

Hi everybody,
for the first time ever I got this funny message:
mail server rejected message: spam or virus detected (#5.3.0)
This happens now with e-mails containing a pdf which I a) have already sent before and b) created on the mac. Checked with another pdf just for testing - same effect. Any other documents work fine - just those pdfs don't work anymore.
Any ideas?
Thanks in advance,
Bettina

Bettina,
There is the possibility of the MS Office and Word being infected (but not the Mac overall) with what are called micro-viri, and are cross-platform. Many AV filters will catch those. I am providing a link where some of us discussed this MS Office infection:
http://discussions.apple.com/thread.jspa?messageID=2782109&#2782109
Let us know what you find? See also:
http://outlandishjosh.com/wp/index.php?p=861
which you will see in that topic linked above.
I have not confirmed the path you chose to create the PDF will transmit this virus, but this must be checked out, and is probably the source of the message you are getting.

Anti virus - detect and delete - in Snow leopard

Hello
They say Snow Leopard has excellent built in anti-virus software, but I'm not sure. I just taken a job to the printer and his PC virus detection said I had serious virus problems on my Mac.
This seems likely, and could explain the problems I've been having with OS applications like Fontbook - it's so slow it's useless. And Adobe CS3 is also playing up, I have to force quit programs, they work OK for a while, then the most basic elements of the application fail (like quiting, and cropping in Photoshop).
I have spoken to Adobe (useless) and I have reinstalled the OS, and CS3.
How can I check and eliminate a worm or virus from my HD and external backup HD.
I'd be very grateful for any help.
John

I'm with you there. I had been running OS 10.4.11 with absolutely no problems whatsoever. Now I have Snow Leopard and CS3. And, the ONLY reason I upgraded to Snow Leopard was to use the iLife suite, which has some software I need. Now there are problems all over the place. I can't use some of the CS3 plugins that I paid good money for, CS3 has a strange artifact that shows up every time it opens (fortunately the artifact doesn't print), video downloads through Firefox, Chrome or Safari have numerous cache issues, startup is slow, some apps crash randomly, and Word doesn't function properly (don't chastise me on using Word. I have to use it.) I've even installed the proper updates and reinstalled CS3 (like you, I can't afford CS5 yet -- starving artist, you know.)
I am VERY disappointed in Snow Leopard (not to mention Apple support). Macs used to be the machine to beat when it came to bugs and crashes. Now a Mac is just like any PC -- you never know what's going to happen.

Trojan Virus Detected

While using Safari a notice stating Trojan Virus detected keeps appearing! Safe Booted once but very apprehensive !?

HI and welcome to Apple Discussions...
Malware perhaps but not a virus. Get MacScan
You can use the demo for 30 days free and runs on Snow Leopard.

Win 7, IE 11 downloading flash installer, I get virus detected even after disabling ActiveX

Win 7 IE 11, ACTIVEX disabled, trying to download Flash installer, I get Virus detected- installer deleted. Any Ideas?

Download the Adobe Flash Player FULL installer directly by right clicking one of the following links ans selecting "Save target as".
Flash Player for ActiveX (Internet Explorer)
Flash Player Plug-in (All other browsers)
Disable the A/V and then run the installer.

Sophus anti virus detected troj/upatre-jl and cleanup failed. how to manually remove?

My Sophus Anti Virus detected "troj-upatre-jl" and the cleanup failed from quarantine manager.
It says manual cleanup is required and I have absolutely no idea how to do that. Need help!

Either it detected nothing at all, or it detected Windows malware in an email attachment. The malware will have no effect as long as you don't pass it on to anyone else or run it yourself in Windows.
Remove the useless, time-wasting Sophos product by following the instructions on this page, and also this one, if applicable. If you have a different version, the procedure may be different.
Back up all data before making any changes.

Virus Detected in inbound e-mail

I have been getting alerts on mac os server pertaining to the mail:
Virus detected in inbound email
A virus was detected in an inbound email. The message containing the virus was not delivered to the intended recipient and has been moved to:
/Library/Server/Mail/Data/scanner/quarantine
It is recommended that you delete all messages in this directory. Messages left in the above location for longer than 72 hours will be automatically deleted.
However when I go look in that folder it is empty (I know it deletes in 72 hours but I look immediately). I get no info on who it was intended for, what was really done with it, if it was a mistake or anything. Am i missing something?
Thanks

I found this post on Google, sorry to dig up an old thread but I'd just like to say you can inspect them this way:
sudo su
cd /Library/Server/Mail/Data/scanner/quarantine
ls
If the files are gz format like they are on my server you can:
zless <bad file name here>.gz
Then use your up and down keys to see the HTML content or anything else. In my case it was actually a legitimate message being marked as spam, not a virus at all!

I have iPad2 and iMac. What is recommended virus detection/protection software to download?

What is the best recommended virus detection/protection software for iMac???

You don't need any anti-virus software. See:
Helpful Links Regarding Flashback Trojan and Virus Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
A link to a great User Tip about the trojan: Flashback Trojan User Tip.
To check for the trojan: Anti Flashback Trojan 2.0.4.
A Google search can reveal a variety of alternatives on how the remove the trojan should your computer get infected. This can get you started. Or the preferred method is to use Apple's protection tool: Flashback Malware Removal Tool 1.0.
Or, open Software Update. If you do not have the Apple protection software installed it will download and install it via Software Update. If no update appears that means you either already have it installed or it isn't needed for your system. The software is only available for Leopard, Snow Leopard, and Lion versions of OS X.
Also see Apple's article About Flashback malware.
For general anti-virus protection I only recommend using ClamXav.

Virus detected in inbound email

We have just upgraded to OSX Server 3.0.3 and am now getting alerts saying "Virus detected in inbound email".
Go to /Library/Server/Mail/Data/scanner/quarantine
When I go to the folder, I don't have permission to get into it even though I am logged into the server as the administrator?
I need to see if these are coming from customer or not.
Any ideas on how to inspect them much appreciated.
Thanks

Is virus detection software suggested. If so, which one?

Is virus detection software recommended for a MACBook Pro? If so, which software is the best.

Have never felt the need myself...

Please add Virus detection App on EX

Please add an App for Virus detection and deletion. Would be gread to have also on Ex an Virus programm to be secure for any virus attact on the network. Regulary computers in the networks are seruce by installing AntiVirus programs. If users enable an all-day sync to the Network storage for data sync there is a high risk to copy an virus to the storage.

you ask and they do it, not bad....

Anyone benefiting from anti-spyware or virus detection?

Anyone with experience or opinions on anti-spyware/virus detection software for our Macs?
I'd like to know if anyone has one worth while to recommend.
Concerned with more and more apps., and blogging sites and websites visited.
Thanks....

Adding my two cents worth:
At this time there have been no confirmed Mac OS X viruses (subject to the semantic debate about whether the iChat exploit from a couple of years ago is properly classified as a virus or a trojan horse and not counting the Word macro virus that can affect Office v.X or non-updated copies of Office 2004), very few trojans and no adware or spyware. I therefore do not feel that antivirus or antispyware software is necessary at this time as long as users are careful about what they download from the Internet or accept as attachments via email.
It's never wise to become complacent, though, so security precautions are not wasted. Such security precautions mostly are common sense: don't download and run files from sites you don't know, don't double-click on attachments in emails you aren't expecting and/or from people you don't know, and make sure you password your system and keep that password secure, In addition, don't leave your your system available in a public place and unattended where someone unauthorized could use it and potentially install malware (such a policy is also a precaution against theft).
It is possible for a Mac user to inadvertently forward a Windows virus to a PC user though you'd have to do it manually so the above precautions would probably prevent such virus-spreading, and said Windows virus cannot infect the Mac.
If you do decide you wish to run antivirus software, I think that the donationware clamXav should be more than enough provided you remember to scan your system from time to time. iAntivirus has also been recommended by others, though I have no personal experience with it.
If you are running Windows on your system, either via BootCamp, Parallels Workstation or another solution, then that copy of Windows is subject to all the myriad exploits common to the Windows world, so you need to take full precautions, including running both antivirus and antispyware software.
Regards.
