Hi everyone here, first of all thks for such dedicated help that this forums represent.

I'm of need of that help :/

See, my pc got infected when I plugged in an infected hd. The strange thing is that somehow the virus jumped to my hd before the Nod32 would load. I didn't have time to even double click that hd before I would notice that the taskmanager was disabled. In fact, I was able to check that hd with winrar and no autorun was present. I'm clueless about that kind of virus that can run on load time, or something like that.

The symptoms are the usual for the heavy virus, regedit and taskmanager disabled, the virus checks every 3 seconds if changes have made into the system... it even didnt let me turn off the active protection of nod32, as I know it's required to run some specialize tools. I havent checked on mine, but another pc with that infected hd can boot in safe mode, but the virus is still present. I can launch the TuneUp process manager as the autostart utility but I'm unable to identify any strange process. Spybot can't load, it's automatically closed. Same for the message whenever I try to open regedit, the "it has been disabled by the admin" is closed immediately. the gpedit.msc is crippled but I fear that was my doing. The virus also blocks Inet access to the antivirus sites, like kaspersky. HJT also doesn't show significant modifications, so I'm really clueless in how to begin. That's why I'm here. Guess it's a rootkit, but no idea how to deal with those.

My OS is WinXP PRO, and... well, what else my I add?

So, I need some serious help here. I just wanna get rid of the virus, I can format the OS after its gone, so no problem about the state of the OS. What I fear is that it can jump again from an infected and partition that I wont format...

Also, on friday I'll be on vacations, so I won't answer. I'll be 10 days out, hope my topic doesn't get closed for lack of answer.

That... thks in advance!!

Is this a USB hard drive we are talking about? If yes remove it for now and let me do some checking
Run this so we can see what we're dealing with
-------------------------------

The process of cleaning your computer may require temporarily disabliling some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note:
-- If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

No, sorry, it wasn't an usb, it was a HDD. He asked me to backup some of his files so I plugged into my system and puf. And no autorun whatsoever. [Sure enough, that HDD is unplugged now]

I did the quick scan with MBAM and all it found was the regedit and task manager registry problem. Nothing else.

Now I can access both task manager and regedit, but the virus just closes them in 1-3 seconds.

Next step? :S

EDIT: I checked if the system can boot in safe mode but everytime I try so, I get a 0x7B BSOD. Also when trying a full scan with the nod32, it logs: "MBR sector of the 2. physical disk - error opening". I set the nod32 to change setting just with a password, but even so the virus change settings back to default. It's getting really annoying.

I was thinking... can internal sata hdd be hotplugged? I could try to connect the infected hdd to a clean system after the antivirus is loaded...

PS: after the restarts, the virus disabled taskmanager and regedit again

Ok, I got itchy, I installed Win7 on another hdd and then run kaspersky on all the hdds. Mostly all threats were the Sality.aa virus, which had infected... well, like every exe on the hdd. I left it running trough the night and was able to desinfect 99% of them. Yet, I think that's just like fever. you may low the fever but the virus is still there. What I found interesting is that I boot to WinXP again, and it had found "new hardware" being something called "RAM PCI controller", or something like that. I think it's the virus installing itself as a service with a random hardware id...

You're obviously anxious and in a hurry. I suggest you try Kaspersky's rescue disk. I have heard good things about it

More anxious than in a hurry!

Anyway, thks a lot, I ran the tools listed in the page you gave me and it all showed up green results, so I guess I'm ready to go. I'll have to format and reinstall the OS though 'cause the virus rendered much of the software installed into a mess, but that's ok, I prefer to have a clean OS. Again, thks v much for the help!!
