• How can I fix a computer that is infested with malware and is extremely unresponsive? [closed]

  - by fredley

  Possible Duplicate: How do I get rid of malicious spyware, malware, viruses or rootkits from my PC? I'm troubleshooting a Windows 7 PC for a friend. A couple of days ago it started running 'slow'. It turns out 'slow' is about 15 minutes to the first glimpse of the desktop, and another 30 to show icons. It is possible to open Task Manager, and nothing seems awry, CPU usage at 1-5%, plenty of memory free. The machine is clearly infested with malware though, in particular a program called 'Optimizer Pro' is demanding money to 'remove 5102 files slowing down my computer'. This seems highly suspicious. My problem is though, that I can't access msconfig (I left it for a couple of hours after having hopefully typed it into the Start Menu and hit enter - nothing seems to have loaded), or anything at all basically. I can boot from a Linux Live CD, but can I actually do anything useful from there? System Restore hasn't fixed it either, and Safe Mode exhibits the same behavior.

• Windows XP Log In: Can't do it. Logon Message popup.

  - by kojobino

  A friend recommended this site to me. Hope you can help! I can't seem to log into Windows. I boot my computer. The log In screen appears. I put in my user name and password, hit OK, and the following message pops up: "The system could not log you on. Make sure your user name and domain name are correct, then type your password again. Letters in your passwords must be typed using the correct case". NOTE: I have tried Safe Mode and the same message pops up. Just to be clear, I am not able to get into Windows (I'm stressing this b/c I've come across some suggestions that require you to be in Windows, which doesn't help in my case). Thanks for your assistance. -Stranded in Toronto

• Recovering data from a corrupted disk

  - by r_honey

  I use an external harddisk to backup my data (it had 3 partitions). Last week when I plugged it in, the OS (Win 7) hung up and I had to force re-boot the machine. When I turned it back on, the system just did not detect the hard-disk. It was last Sunday and I had to give up after sometime. Now I return back next Sunday (today) and when I plug it back-in to the machine, the OS detects the disk as well as all the 3 partitions on it. But it says all 3 are unformatted and I cant access any of them. Is there any way to recover data from the 3 partitions (I tried PC File Recovery and Recuva from PiriForm but neither detected these partitions).

• What's a worthwhile test for a new HD?

  - by Michael Kohne

  I work for a company that uses standard 2.5" SATA HD's in our product. We presently test them by running the Linux 'badblocks -w' command on them when we get them - but they are 160 gig drives, so that takes like 5 hours (we boot parted magic onto a PC to do the scan). We don't actually build that many systems at a time, so this doable, but seriously annoying. Is there any research or anecdotal evidence on what a good incoming test for a hard drive should be? I'm thinking that we should just wipe them with all zeros, write out our image, and do a full drive read back. That would end up being only about 1 hour 45 minutes total. Given that drives do block remapping on their own, would what I've proposed show up any infant mortality just as well as running badblocks?

• Why can't my FreeBSD 6.1 (vmware player client under Win7) do DNS in Bridged mode.

  - by Walter Stickle

  I have a 64-bit FreeBSD 6.1 client, running under Windows 7 (64-bit) via VMWare player 3.0, with networking set to bridge mode. DHCP goes fine on boot... I get correct adress/gateway/nameserver info... I have good connectivity to the world in that I can ping any host I can name by IP addr, (including both of the nameservers in resolv.conf,) ...but I can't resolve any names. Inside the Windows box, the network interface has VMWare Bridge Protocol enabled, and the windows side of things has full connectivity. dig replies with: ;; connection timed out; no servers could be reached ...even if I use "dig @server_ip_addr" to point it at a pingable, working nameserver If I set VM networking to NAT mode, I can get outbound connectivity (with happy DNS) but, of course, can't do INBOUND connectivity, which I need. Thoughts?

• Remotely enter encryption key?

  - by Jason Swett

  This might be a really dumb question but here goes, anyway. I just bought a couple servers. I already installed Ubuntu with encrypted LVM on one and I'm planning on doing the same with the other. This means that every time I boot up each of these machines, I have to enter the passphrase. And I'll have to do this every morning because I'll power each machine off each night for security reasons. Here's the problem: I don't have monitors or keyboards for these servers. It seems to me I have two options: Somehow enter the passphrase remotely Buy a KVM switch I doubt #1 is an option but I want to make sure it's not before I buy a KVM. Is it possible to enter the passphrase remotely? AND is it a good idea?

• Question about getting information off an old HD...

  - by user37983

  Ok so my old cpu was a sony vaio. its kinda old and had xp on it. My gf thrashed it - the cd drive went and she tried fixing it by messing with the configurations bios etc. the actual laptop is really fried the keyboard doesnt work, etc. However the harddrive is still intact. I tried putting the HD in my new cpu (toshiba runnig win7) and it looks like its gonna boot up it goes to the screen with the logo and the status bar starts to load. then it flashes a blue screen for a split second, and goes to the black screen where it says windows did not shut down properly and gives options to (start windows normally, safe mode, safe mode with networking, safe mode with prompts) ive tried every option but it always goes back to this screen. I need to get into the hd cuz i have very important files. is there anyway?

• Readyboost on Windows 7 x64

  - by RobLaw84

  I'm thinking of bying 1 or more flash drives or an SD card to use with the readyboost function on by 64bit Windows 7 machine. I have a few questions regarding it before i put my hand in my pocket and buy anything. If i go ahead I would be using the fastest available flash/SD. I have 6GB of RAM current installed so will readyboost make any difference to boot / program load times? Will 2 x 2GB flash drives be quicker than 1 x 4GB or is the limitation on the motherboard? Would an SD card better than USB flash drive? thanks

• compiling the linux kernel

  - by user482819

  Just for learning, I have recompiled the linux kernel with different options, installed and boot from it. It was both instructive and straight forward. However, I was overwhelmed by the big number of options available. My questions are: 1.- Does it make sense to spend time trying to optimize the linux kernel for my particular laptop? Will it make a significant improvement? 2.- Is there any tool that can read the configuration of my computer and suggest a config? Thanks, H

• Windows 7 network share issues w/XP & SBS 2K3

  - by Kevin K

  Hi, my Windows 7 Ultimate 64 bit computer has issues when accessing SBS 2K3 or XP shares. 1) It will not automagically reconnect upon boot. I have a batch file that will do this that utilizes net use (yes I have /persist:yes, but it does not help) to re-map them. 2) After trying to use it for a few minutes, it will not work. Any attempt to access the drive letter that was mapped causes windows Explorer, or other apps. to lock up. These shares work fine from XP & Vista computers. When this happens the internet works fine, just the mapped drives do not work correctly.

• ASUS N550 laptop not charging on ubuntu after updating kernel

  - by OBY Trance

  I'm using Ubuntu 13.10 on a pretty new ASUS N550jv laptop. When I was using kernel linux-image-3.11.0-11 everything was quite well (kinda..), however, when I updated the kernel using the automatic update, the kernels which were released afterwards (12+) were faulty on my machine, and caused the battery not to be charged and only stay at their current charging level (even when the machine was off!) The only fix I had was to roll-back to the '..11' version (on boot screen - advanced options), and hard-reboot (AC cord disconnected and reconnected) but now version 14 was released and "pushed away" the good old version 11. How can I fix that?? Please help me...

• Cloned Windows 7 to new HDD and want to change the drive letter to C

  - by Hoppe

  I used Clonezilla to clone my existing hard drive to a new one I bought. I then changed the BIOS to set the new drive as the first in the boot sequence. I'm pretty sure that I'm still running Windows 7 on the old drive. My old drive is marked as C. Now that I don't have a disk drive any more, how I do I swap the drive letter from J: to C:? I tried to change it in the disk management section of "Manage", but it reports: "the parameter is incorrect".

• I want to "image" 40+ laptops quickly...i welcome suggestions on reliable software

  - by Joldfield101

  I often have batches of laptops/PC's to re-image and have tried various methods, but each of them has been problematic and often take more time to troubleshoot than it would have been to image them individually! For example, i have tried to use ghost - i installed ghostcast server on my laptop but the clients never seem to boot to LAN successfully, or it takes an hour to get everything sorted (drivers, LAN, DHCP etc etc). I want a reliable tool that makes imaging quick and easy - and i don't mind paying for it if it's going to work (but obviously free = always good!)

• permission for "users" directory for a mounted vmdk file

  - by rajmalhotraml

  I mounted one vmdk file in my windows 8 machine and I am able to access all the folders and files except those in "users\ directory. When I try to open, it says I dont have permission. I am not able to give the permission even. Any one can tell me how to open the users directory? I have very important files in the desktop folder which can be acessed through \users\\desktop. What is the alternate way of accessing the folder? I lost the password to boot up the vm image.

• Removing BIOS Post Messages

  - by Steve

  I am working on a project where a standard x86 desktop system will boot and run a single program until it is shut down. I would like to remove all the bios post messages so that it looks a little more "finished" and cleaner when it starts up. I was hoping that there might by a standard implementation/terms to know about so I can avoid having to dig through every manual to see if there are options, or get some advice on a standard set of tools I should be using. I was thinking about getting a board that has an image that covers up the post messages until you press a key and trying to customize it to all black, but it's not clear if this is a good direction. I started looking for OEM motherboards but my searches were filled with standard commercial stuff, or seemed to be way to big for my toy project. What is the best way to go about removing all the bios post messages and just having a blank screen or "loading" message until OS loads?

• Ubuntu Wired network(ethernet does not work)

  - by badnaam

  It was working just fine, until the other day I yanked it out. The wireless works just fine on the same router. If I login to a windows 7 instance on this dual boot laptop then the ehternet works just fine. So it's not a hardware, cable or router issue. The card even gets an ip, but I can't connect to the internet. Here are the details from route, iptables, ifconfig, ping etc. Any ideas? I have been struggling with this for day, none seems to have an answer. http://pastie.org/954816

• How to get the finer resolution for asus eee pc 1000hd after installing windows7?

  - by vij

  Hi i have installed windows 7 on my 2 year old ASUS EEE PC 1000HD. The default Operating system it came with was windows xp. Now the system is working fine but there are some display problems which i am going to state now: Firstly, during booting windows 7 logo is missing. There are no options for resolution changes. The only option possible is 800x600. The boot time is quite long when compared to xp. The graphics driver used in this system is STANDARD VGA GRAPHICS ADAPTER. The processor is intel celeron with 1GB RAM. I think with these requirements it is possible to get windows 7 with finer resolution. But why these problems are occurring?I even tried to install graphics driver provided by intel for this system. But i ve got the error message "this system doesn't meet the necessary requirements". So how to overcome this problem??

• Run command on init and restart on errors

  - by chersanya

  I have internet access on my PC through proxy through SSH, so every time I need to execute ssh -L PORT:SERVER:PORT LOGIN@SERVER and then type a password. After each network failure or reconnect this command has to be executed again. I've got bored of it and look for a way to do this automatically: first run this after boot (it doesn't seem to be a problem - put this command in some init file and that's all) and then rerun it (if possible, then type password) on each network failure. Is it possible, and how? OS Linux (Debian)

• DIagnosing another Windows 7 Lockup

  - by MSEoris

  Im running windows 7 on a fairly modern machine (8gb ram, amd fx-6100, gtx 560ti) and I notice that periodically my windows seems to just hang for a little while. Frequently this occurs after a cold boot and i start up five or six small to medium sized programs, but also occasionally it occurs during normal usage. Basically what occurs is the screen locks up, there is no keyboard responsiveness for a period of 30 seconds to a full minute - after a bit of patience, control is returned, but I'm interested in figuring out what is causing such lockups. I checked the event log and dont see any issues, and all i can see in task manager is a spike in cpu and memory usage right after this occurs. Any tips on how to even begin to diagnose this? Thanks.

• enable tcp_syncookies even after reboot

  - by Tim

  I'm running Scientific Linux 6.1 and would like to set net.ipv4.tcp_syncookies=1. I've set that in /etc/sysctl.conf and, if I do a sysctl -p then sysctl -q net.ipv4.tcp_syncookies it shows it's properly set. Sadly, if I reboot the machine, and sysctl -q again, it goes back to 0. I've tried to grep around and see if something else is resetting it to 0 during the boot process but haven't turned up anything. I've googled and everything points to sysctl.conf. The only thing I can think of is maybe networking isn't up by the time that file gets read but, honestly, I'm a developer and well beyond my natural skills here:) I'm tempted to just set it directly in /etc/init.d/network but then that feels hackish and so, I thought better of it and I'm here in search of the "right" way to do it. Any pointers?

• Debian Based Server not booting, soon after GRUB screen it restarts?

  - by Krauser

  I have tried running memtest, it start get about half way then abruptly restarts. I assume this is not a problem with the OS itself but rather a hardware issue, I have checked various logs when after about 10 reboots it starts ok, /var/log/kern.log /var/log/syslog /var/log/dmesg All I get is: EXT4-fs(sdc1): re-mounted. Opts: errors=remount-ro restart So I ran fcsk on the drive, to check if the fs was failing and it was fine. Really don't know how to find why the server is continuosly restarting andif I get lucky it will boot up.

• Vista Startup - Cannot Find the File Specified

  - by Redmastif

  Yesterday I restarted my laptop because my Wi-Fi catcher wasn't working correctly, and when the computer reached the login screen, instead of showing my user account it said "Cannot find the file specified". I rebooted and ran the Startup Repair and Memory Diagnostics but nothing showed up. I also took the battery out for a minute and tried again but still no luck. The weird thing is that I cannot even boot into safe mode, it still shows the same error. I don't remember downloading or opening anything suspicious recently, and I have 3 different cleaners/anti-malware programs as well that I usually run about once a week. I did go into the registry recently but I didn't modify or delete anything as I was only checking to see if I had a certain key in it. I have a Dell laptop running Vista Home Basic SP2. If I have to I can reinstall the OS with the CD or even take it to Best Buy but I'd rather try and fix it first. Thanks.

• Timing startup processes?

  - by acidzombie24

  My Windows 7 use to boot up fast and now its getting rather slow. I suspect one program is eating up all the time yet i cant tell what it is since task manager shows <40% of the cpu being used. What can i use to track how long each process takes when my computer boots/starts up? Note: Except for launchy which i used before my comp became slow, all my startup and services are all signed and known (broadcom, VMWare, Google Inc, Intel, etc) Note2: I am mostly considering the time it takes after i login but i suspect the time before that is slightly slower (i dont think very much though)

• How do I justify to my management that we need a bandwidth upgrade?

  - by Sandeep

  I work in an office with a 8mbps line and about a 100 people. Our internet has slowed to crawl over the past few months, as we added headcount. However, using speedtest.net or other sites, still shows bandwidth as 8mbps. Now, how do I justify to management that we indeed need to upgrade our bandwidth ? Please note that I dont have access to our main routers or any network equipment. I can only use my system (windows+linux dual boot) to make a case for a reasonable justification. help!
