Installation :: Virus Locked Everything - No Access To Drive
Jun 18, 2010
I'm currently using Win Xp and am having a major issue with a virus. I told a friend I was thinking of reinstalling windows, but he suggested Linux. He made me a disk with Linux on it but the problem is is that the virus has locked everything up so I can't access my D drive and the cd won't start automatically. I'm also unable to run most downloads...
My questions are:
Can I safely delete the partitions that Win XP is on and install Linux on after that? Is there a way (if I can make it work) that I could download Linux from the site and run it right off my computer without first putting it to a thumb drive or cd?

rescuing my machine after an unfortunate incident with what I assume is a faulty thumbdrive.The other day I bought a used HP 2140 netbook; which had a 1.6GHz single core Atom, 2G mem and a tiny little harddrive. I got it home, put my ssd in it, and within an hour had a nice clean ubuntu netbook edition installed on it. And everything was joy, mostly, for a couple days. But Netbook edition was not as fast as expected, and I wanted to try another distribution. So I put Xubuntu on a new thumbdrive, and tried to install it. Some time during the file copying process, it stalled. I left it on overnight, then turned it off.
I've tried a few distribution iso's; Ubuntu desktop, xubuntu, linux mint. Same thing every time: Installation hangs after clicking next at the screen that checks for specs, space and online status. I can boot from another thumb drive with little trouble, but cannot install from there either. I've tried running GParted, but running it from the meny leads to it crashing. Running it from the terminal still crashes; running it with 'sudo gparted /dev/sda' it runs, and from here I can do most things; I can remove and create partitions, and format to my hearts content. But trying to change flags brings up this error: 'Failed to mount "Uden Navn" The enclosing drive for the volume is locked'. When I close that popup, this comes up in the terminal: 'udevadm settle is not permittet while udev is unconfigured'
I understand that the drive could be locked somehow because of the crash. So I took it out, connected it to another machine, removed the partitions and changed to a guid partition table, and made absolutely certain that the drive had finished ejecting before disconnecting it. Nothing. I tried another harddrive: Nothing I've reset and flashed the bios: Both nothing. I've tried updating GParted; it tells me I have the current version. I've let Xubuntu run thru its updating process from the thumbdrive, and even though it gives me a couple errors underway, it gets thru. But it doesn't help

I have a Western Digital Pasport 320 GB hard drive. I wanted to create a live installation on it like a USB stick. I wanted it to serve as a portable OS that I could use to boot any other computer off of, and use it for diagnostics and anti-virus scanning on Windows based computers. The additional space is for my own personal use, kind of like having a mobile desktop where I have all of my documents in one place.What I need to know is how to set up Fedora 11 so that the hard drive will boot on most PCs regardless of their architecture. I also need to know what's a good Anti-virus to install onto it for the sake of fixing Windows hard drives.
Please keep in mind I'm a noob when it comes down to a lot of things, so if there's an antivirus I have to install manually, please included a step by step.

Installed Ubuntu 9.1 karmic koala in a dualboot with Windows XP to remove a virus from the windows drive. I think the virus was found but somehow I have done something to cause a invalid drive error message at startup. I read that gparted may by a way to fix this, but I don't want to do anymore damage.
This is what is displayed when I start Gparted /home/ubuntu/Desktop/Screenshot--dev-sda - GParted.png [IMG]file:///tmp/moz-screenshot.png[/IMG][IMG]file:///tmp/moz-screenshot-1.png[/IMG]

A while back I had been using ubuntu on a live cd after my windows partition had been taken over by a virus, which at the time I thought had been removed by my anti virus (and then took out winlogon) and I did a system repair instead of a complete reformat because I didn't want to lose all of my files. After repairing, I noticed some things like what looked like fake "this page has been blocked based on your security preferences" on major sites like ....., myspace and facebook. I ran another virus scan with a different AV and strangely it detected a behavioural software keylogger, which after looking it up seemed to be something that could only be installed with physical access to the system, which confused me. Anyway, this is when I started to use the live CD to copy some of my music, videos, pictures etc. onto my flash drive. From what I can remember, I used this USB on my main computer without problems, but the last time I used it (few months ago) I ran a virus scan afterwards, just to feel safe and it came up with a couple java exploit trojans. This was probably just coincidence and I hadn't ran a scan in a day or two, possibly even a false positive as I noticed no decrease to system performance or any odd happenings.
So, my questions are: Is it even possible for a virus from a windows partition to copy itself to a USB flash drive on an ubuntu live cd; and is it possible (if the virus was even capable of this) if I insert the flash drive into my ubuntu computer, it could do anything like transfer across my WLAN to my windows computer, or even copy its files onto ubuntu but be unable to do anything? Which brings me to another question: if I visit a website that may contain drive-by malware or a virus of any type, is it capable of acting at all, such as even trying to transfer itself into my home folder, or does it not even recognize ubuntu at all and do nothing?

I have a small problem with my Acer netbook (ao521) on which I dual boot windows7/ubuntu. I am new to linux and I didn't know much about dual booting so I made some errors when pratitioning and installing ubuntu (originally I had windows 7 only) but that is another issue.
The problem is that I accidently wiped the /C partition of win7 thereby deleting windows (). I had made a backup since I knew something like this could happen and I saved it in /home so now it is in /home/backup. Here it gets interesting though..I tried recovering Windows (with the built-in Acer eRecovery) and apparently this messed up Grub so I couldn't boot ubuntu..Now, I don't have a problem installing windows from scratch and then installing ubuntu afterwards (I have learned my lesson and I think I would do it right this time), but there is one folder, which contains some valuable documents and I want to access it and save the documents on a USB drive.
So, I ran ubuntu from the live cd(usb) and I mouned the /home partition (of my previous installation) and I tried accessing the backup folder that I made earlier but it said that I do not have such permission. I did some searching arround and I found out that I should mount the partition as root and copy the contents of the folder from the terminal. So far so good, but when I wrote
Code:
sudo mount /dev/sda9
it said that no such mounting point is available in /etc/fstab.
It occured to me that I could use the data in the initial /etc/fstab (from the initial ubuntu installation) and insert what I need in the current fstab. I did that but when I write /home as mounting point it apparently confuses it with the current /home so that doesn't help.
Well my question is: how can I edit fstab so I would be able to mount the partition and use it or is there any other way to access the folder in question.

I use my ubuntu laptop at work and connect a lot of usb pen drives to my computer. Everyone else I work with use windows and I want to make sure that the usb pen drives don't contain any windows viruses so I don't spread them. The best way for this to be done would be to have the USB pen drives automatically scanned with they are inserted in my ubuntu machine. How to do this?

I am sometimes getting the following msg, asking me for a password... enter password for default keyring to unlock, the application 'Account Manager' (/usr/libexec/mission-control-5) wants access to default keyring, but it is locked. I have never seen this before and I have no idea what the password would be (since I've never set a "keyring" password).

I'm a software engineer that has recently tested our hard drive locking feature; I discovered an issue that prevents the user from removing the hard drive password and I used a lot of drives to narrow the issue down. Is there any Linux utility/command that can unlock drives?
There is a windows based utility here: [URL] but you need to pay to use it. I guess I'm looking for the free Linux equivalent, if there is any. FYI: The Locking is performed at the firmware level of the hard drive so a low format will not unlock it. This is a specific feature most drives have that not a lot of people know about.

I have an external hard drive with many files on it and i can't do anything with them as none of them is accessable. They have the lock symbol and the cross. I thought i would be able to right click and change the permissions that way but it seems not. They were readable a few days ago when i had UBuntu 9 installed on this computer but i just installed Ubuntu 10.

How can i download free pen drive virus scanner? I need good one? Most of computer gets attacked by viruses through flash drives or usb drives or pendrives. If we can scan and delete it before using it we can make our computer safe.

I want to use my flash drive, but I had files I put on using Ubuntu a few weeks back. Now I can only open them in read only copies and can't remove them, from the flash drive. I also have had some issues with file permissions on the hard drive. I was planning on reinstalling after a backup but now I don't know if that would be logical because the files might all be locked. I wanted to reinstall because I have issues with USB and these file issues.

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.

I've installed F10-live.iso onto a usb key but am having problems with the non-privileged user I created. When I login as kurt, I do not have access to my home directory on the hard drive. I tried [root@localhost home] #chmod kurt kurt (after cd-ing to the correct spot), but still cannot access my files there. I can do so as Live System User, but not as me.

This "An Application wants access to the keyring "default", but it is locked. Goes on and I've a few question about the procedure.
The first is how do I determine WHAT application wants access. Seems to me that I need to know what is going on with programs trying to log in.
If I knew what program is needing access, I could determine if I wanted to provide permanent, temporary, or no access.
How can I determine what is happening at startup.

I have an hp laptop and i had ubuntu on it for 3 years. my hard drive started to fail a while ago (i had ubuntu 10 on it until 1 week ago) and a then it all went black...I took the laptop to a repair shop, they told me it was the disc, so i bought a new disc, installed it on my laptop and reinstalled the new ubuntu 11. so far so good. i have now a working OS, internet connection and i can in fact type this message.
The thing is: all my files are on the old drive, which doesn't load/boot/start/read anymore. I have tested it on some friends's pc, tried a few HD disgnostic tools, they all send the same message: "fail"
I then tried to mount my old drive (with all my precious files in it) on my laptop as an external drive (usb) hoping that ubuntu 11 could read it as an external usb key: it gets read by the system, but it shows no files at all. it also shows an error message saying the drive can not be mounted, with some "sdb1" thing. i am sorry but i'm really dumb when it comes to tech language.
Then i tried to boot it on start-up but i got the grub rescue> thing and nothing else, just a sad, blinking cursor to recover my files,i have also tried testdisk but couldn't understand very well how to use it, and then photorec, from which i recovered bits and pieces of files, with no name. some of them are just parts some of them are complete.
My problem is: i have to get access to my files, as I use them for work, i couldn't do a back-up recently and i have some real important deadline to meet... for which i need those files. is there any way i could solve the grub issue and have that drive load/mount again as external usb?

I got a free flash drive from Columbia College that has some files I want to remove. I did the right click thing and they are read only. I tried to change to read and write but I got. Sorry, could not change the permissions of "ColumbiaCollegeViewbook.pdf": Error setting permissions: Read-only file system
Now this thing only shows up as 5.4 MB Yea that is right Megabytes! But I have a plan for it. So is there any way to get the files off so I can put mine on it?

I have two external hard drives. One is a 2.5" 80GB USB HDD and the other is a Seagate 3.5" USB 500GB HDD. Both hard drives are mounted properly and I can access the data on both hard drives. I can access the small 80GB HDD via ssh from another computer and delete files, but when I try to access the 500GB drive via ssh it says access denied. When I try to access it with root, I can access it but I cannot see any files listed.

I have a rather frustrating issue here that's been giving me hell since about 5:00AM this morning. I just got a new laptop (a Compaq CQ42-138TU) and was hoping to dual boot between Ubuntu 10.04 and Windows 7 Ultimate (64-bit).So, I partitioned the HDD (leaving the HP/Compaq restore partition and other partitions alone) and resized the partition that held the bundled copy of Windows 7 (32-bit). I resized it into two parts, installed Windows 7 Ultimate on one, and Ubuntu on the other. That's where the problems began.Selecting "Windows 7 (loader)" in Grub presented me with the first few second of the bootscreen, then a BSOD for less than a second. After that, the machine immediately rebooted and got back to Grub. Ubuntu still booted fine, but I wanted to get access to Windows back, soI attempted to fix this by running:
Code:
bootec.exe /fixmbr
through CMD.exe on my Windows install disk. Now Grub is gone, and I'm stuck with Windows that still won't

I am running a hp dv701175nr laptop and am booting ubuntu 11.04 from a usb flash drive. I can not seem to find my internal drive that has windows 7 stored on it. I tried to mount it but it give me this error:
Error mounting: mount exited with exit code 1: helper failed with:
mount: according to mtab, /dev/sdb1 is already mounted on /
mount failed
I can't use this operating system if I can't access my windows 7 drive and I really want to use this OS .
EDIT: Okay, so I think I have found my problem, but I don't know how to fix it, there are differences in my mtab and fstab commands, I will post what they say in a second, but I do not know how or what I need to do to change and make the settings right

I have Ubuntu 10.04 installed. When I run Ubuntu 10.04 LiveCD and I start GParted I see that there is a "key" on my swap partition marking it as locked I guess. When I right click, I cannot select "Delete" option. What does this mean? What if I want to rearange my partitions sizes including swap partition for whatever reason?
