Let's say I have an avi file that contains a virus for ntfs windows xp sp3. I put that file on a linux ext3 partition. Then on a windows xp sp3 nfts computer, I connect to the partition over a network share via smb. I run the file within the share so the file is never physically on the windows xp sp3 computer. In this situation will the virus infect the windows xp ntfs partition?

View 3 Replies View RelatedI am a very new Linux user. My first OS is Fedora 12, which I just recently installed into my laptop. So far, I am thoroughly enjoying it. I do have a question bugging my mind though. Linux systems are known to be very safe from viruses, mainly due to programmers targeting the Windows platform. In Windows, common methods for virus infections are from infected executable files, external drives autorun... ETC.
Now my question is how do viruses spread into a Linux system? And with so few viruses known to exist for Linux systems, do I really need to be aware and take precautions for viruses (For example in Windows, disabling autorun function for external drives)?
Now however its not letting me resize the Windows partition, mounted or unmounted. It currently occupies the whole disk. I would rather not reinstall the whole thing over again, but I will if I have to. Isnt there an easy way to shrink a Windows partition? I swear Ive done this before and it wasnt this hard. Could it be a problem with the Mint installer that now asks me if I want to unmount my disks before it goes into install mode? On this PC I would like to have
Windows XP
Mint
Ubuntu-Studio
Edubuntu
One of the E17 OSs
Puppy Linux (to create a remix)
I am probably going to put most of the linux partitions on the second laptop drive but I want to install files on a non WIndows NTFS partition.
My machine that is running Windows XP got a virus a few months ago. Keep in mind I have NEVER used Internet Explorer.
Symptoms when CONNECTED to the internet: My volume is turned down on start-up. When the volume is on the internet explorer "clicking" noise plays frequently. In task manager there are two "iexplore.exe" processes running. As soon as I kill them they will start up again. They aren't taking up copious amounts of memory, but they are still very present. If left on for long enough pop-ups will start appearing.
Symptoms when NOT CONNECTED to the internet: None.
What I've done: I've ran a handful of the free Anti-Virus programs, e.g., AVG, ComboFix, avast!, and Malwarebytes' Anti-Malware.
Since Wine recognize the .exe filetype and associates itself with it, is it possible to get a virus that starts up automatically in wine or is it limited to me manually running the program?
View 6 Replies View RelatedI believe the name of the virus is "PC Defender 2010". This has self-installed, causing popups attempting to convince the user that there is a security flaw, and that they should upgrade to the advanced version. I have looked this up, and it is definitely a virus. The virus creates a shortcut with a target in the AppData folder named defender.exe. When I went to search for this file, after having set it to show hidden files and folder, I looked in the folder, and found nothing by the name of defender.exe. Does anyone have any ideas as to how to find this file, if it even exists, and then remove the virus all together from the computer. Ideally these solutions will be executable from Windows, as the user is rather afraid of linux.

View 4 Replies View RelatedMy Windows machine crashed, and I am at the mercy of my Ubuntu live-CD to solve all of my problems. I am backing up my data as I write this post. I was wondering two things: 1.) Is there a way to scan my Windows partition for viruses through the Ubuntu live-CD? I don't care much about repairing the partition, I just want to know what happened.
2.) And a few non-linux question: If I back up an infected file to an external hard disk, is it possible to infect another computer by merely connecting the disk to it? Is it possible that multiple, or all of my files have been infected? Is there a way I can open files safely on another (Windows) machine without (or at least minimalizing) fear of crashing it?
I know that there is little need for me to install an anti-virus etc - but - I was thinking, it is a good idea to scan folders and files that I send to colleagues that run windows.Whats the best way and programme to do this? I guess I simply install an AV programme and thats it!

View 9 Replies View RelatedLately, I've found 2-3 times an .exe file with a random name in my /home, and another data file with a random name as well. I'm a user of wine, but none of the programs that I use seems to be the cause. Last time it happened I sent it to virustotal.com, and this is the result: [URL].. So, this is clearly a virus. The two files show "nobody" in the proprietary field and "none" as group. What can I do to track down the cause? Also, telepathy-butterfly likes to hog 100% of CPU lately, and all I can do is killing it: is someone exploiting a vulnerability? if so, why the hell would he drop a win32 virus?

Some people say you do not need a anti-virus program like Norton or Kaspersky or any firewall.Other people say you do and some say that Unix and Mac OSX have built in firewall.
And if on uses windows use ZoneAlarm or Comodo has it does alot more than windows firewall and router firewall. Note the admin saying the other thread was why windows get more malware and not very much the subject of the thread to post there.
I have been told that some virus scanners for linux (including but not limited to AVG, Antivira, clamAV, others) are available to ubuntu. My question is which of these still CURRENTLY support detection of WINDOWS viruses in addition to linux viruses. I would like to boot the Ubuntu live jump drive I have to scan windows machines and at least detect viruses, dont really need to repair. who knows which virus scanners compatible with ubuntu that will detect windows viruses as well

I have a dual boot computer. The WindowsXP "side" has been infected with a rootkit virus. So far UBUNTU has not been affected to my knowledge. I have not yet removed the virus from the WindowsXP "side". I am thinking of deleting the NTFS partition and have the computer fully dedicated to UBUNTU. Now for my question. Is there a possibility that the virus resides in the MBR and that I need to "rebuild" the MBR to actually remove the virus?
Even more extreme, should I totally re-install UBUNTU in the name of safety and precaution.
if there is any free software there used to protect Fedora from spyware and virus?

View 3 Replies View RelatedI was attempting to format a flash drive, and well, used the wrong sdX device. I've run DiskInternals Partition Recovery tool, and all my files are still there (you have to pay $139 to have it restore the files). Is there any way using tools in linux to restore the ntfs partition/files? It was a single disk with the partition taking the entire drive. I've tried mounting it with the -t option, but it says invalid ntfs signature. Man, two lessons the hard way, make sure you backup (duh) and be careful what you type as root.
View 8 Replies View RelatedSo I am reaching an unfortunate conclusion. I asked this of google and got no straight response so I conclude that it is impossible. taking a look at GParted with my 10.4 boot disk, I see
/dev/sda1 NTFS 74GB boot flag
and
unallocated unformatted 7.84GB no flag
So I assume that that 8gb used to be ubuntu.
In the process of trying to fix things, the computer no longer boots windows.
This is not a question, I have done it. I just want to post a little howto in case anyone runs into a similar problem.I will not go into particular details, just the rough description. If need details on something, I'll be happy to explain the part in question.
I am working on linux for almost a decade now. However, there are some things that need to be done on windows, like gaming (ATI drivers for linux are still a bit tricky, especially for newer cards) or rs232 (serial port) based apps (old smartphone management, PIC or ATMega Programming, old graphic calculator like TI92 etc.).So in short, I had once set up a windows system. I wanted to use my files both under linux and windows. The solution for this problem is obvious: I used a NTFS partition I could mount under both OS.Since I am a security concerned citizen, I use to encrypt my disks. However I refused using Vista and Win7 hadn't come out yet, so I was running XP64. The opensource LUKS tools didn't work on that system (driver issues), so I used Truecrypt.Some time ago, I abandoned the windows partition after a fault in the MBR, which rendered the Truecrypt bootloader unusable (yes, even with the rescue disc). Since I rarely have to time play games anymore, that's not a major concern. The rest of the tasks can be handled using a virtual machine (in my case Sun's VirtualBox).So, after about 10 months, I had ended up with a severely fragmented, Truecrypt encrypted NTFS partition which badly needed defragmenting. Linux NTFS-3G drivers have become fairly reliable, but their reliabality decreases as the filesystem fragmentation increases. And the only OS which can defragment a filesystem of this time is windows NT.
Procedure:
The basic underlying problem is that you need to access your raw device from a windows system that by itself lives in an isolated virtual environment. The SMB/CIFS shares are ok to access data, but NAS Filesystems rely on the servers filesystem and cannot be defragmented.What can be defragmented is a SAN share (iSCSI target), because the protocol by itself forwards the device to the host over a network, not the filesystem.
(1)So first of, make sure you have a virtual machine running windows somewhere. it actually doesn't need to be virtual, it can be a remote computer on the same subnet, but in my case, it is a virtual machine. As I said, I used VirtualBox.
(2)Next make sure the Windows box has access to the same network as your linux host. In VirtualBox I used a network interface in NAT mode. I suppose you could also juggle a second loopback device around on the linux host to fulfill the same purpose and keep the windows box of the public network if that is a concern.
(2.5)If you have encrypted your NTFS partition, you need to decrypt it (not mount it!). Using LUKS, use the cryptsetup command to create a decrypted alias of the partition. If you have used Truecrypt, use it's frontend to mount the partition as you would if you wanted to access data, then unmount the alias from its final mountpoint, thus leaving the unencrypted frontend to the partition intact.
So now you have:A linux host with a fragmented NTFS partition (which might be encrypted) that is not mounted.A windows machine (either virtual or remote) with access to the same subnet as your linux host.
(3)Next you need to setup your unencrypted partition alias as an iSCSI target.
I have installed Debian as a second OS alongside Win XP, and now I have Win XP on C drive (if viewed from XP), NTFS, my data files (mainly texts and graphics) on D drive (NTSF), and Debian on ext3. Debian sees and opens files on D.
1. If I read-write from-on this D partition from both OSes, is there a chance the data will be corrupted?
2. If I open a Windows-created TXT, GIF, JPG, HTML or other not-proprietary format file from Debian, edit it and save (just SAVE, not SAVE AS) - will this file remain readable from Windows?
I have a dual-boot system, Windows XP on primary HDD and Fedora on Slave HDD. NTFS -3G is installed in Fedora, but I would like to hide (or not mount) Windows system partition on Fedora boot, as I have multiple users in Fedora and do not want them to access this partition. I do want to mount/display my NTFS D: partition in Fedora. Is there a way to exclude an NTFS partition from mounting by default?
