Hi! So, I'm not really familiar with stuff like this, so if I blurt out anything stupid, do excuse me.

Before I start panicking, I'd like to ask if my pc is really infected. I was checking out the various running processes that I had when I found an extra svchost.exe process. Usually, my pc only has 4 of this, but yesterday, there was 5 of them, I read some articles about svchosts and found out that this was normal ( that is to have multple svchost.exe running). So what I did next was check out the services which were using them, and there I found these two - RemoteRegistry and Lmhosts. I've tried removing (is this the right word?) RemoteRegistry by using processexplorer but failed, I got some kind of error (I'm really sorry but I couldn't remember what it was).

So are those two really viruses(or maybe trojan), should I really start panicking now? Am I just being too paranoid?

Edit:
By the way,I'm using XP service pack 2

Let me start out by asking a question.

Is this computer connected to a network or domain? ( is this a work computer )?

Remote Registry Service is started by svchost.exe and is used to allow remote registry access ( in controlled circumstances ) to your computer. Allowing for changes to be made to your registry on your computer. There are many different trains of thought on whether or not to disable to keep enabled the Remote Registry Service. I for one leave it on.

LmHosts -

There may be instances when you experience name resolution issues on your TCP/IP-based network and you need to use an LMHOSTS file to resolve NetBIOS names. This article describes how to create an LMHOSTS file to aid in name resolution and domain validation.


The above quote is directly from Microsoft themselves.

Are you being overly paranoid? I don't think so. You are being proactive in learning "what is it" and "what does it do". Are they viruses, the chances are slim but there are ways to check.

If you are on a network with a domain and both of these services are running, it could be that the administrator of your network enabled them specifically.

Hope this sheds a little light,

No, I'm not connected to a network or domain, this my main PC( well, my only pc lol) which is why I'm wondering why that service is running, since I don't remember installing any program which requires both.

You probably did not install anything that needed these services. They are enabled by default when Windows XP is installed to begin with.

Actually, this is the first time I've seen both of these service (I've been monitoring my pc's running processes for a while now, so I'm quite sure of this) which is why I'm pretty freaked out. --;

Well then, let's do a little scanning of your system to be sure things are on the "up and up".

Scan for Spyware/Adware

The process of cleaning your computer may require you to temporarily disable 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 Free version and save it to your desktop.

NOTE: Before saving MBAM please rename it to zztoy.exe....now 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
---------------------------
Be sure to re-enable your AV and malware scan tools if they were disabled

Well, I already have MBAM in my pc, just to be sure, do I still have to rename the exe into zztoy.exe?

Also, this might take some time (maybe even days), hopefully you don't get fed up at waiting. And before I forget, thanks for the instructions.

If you already have MBAM on your machine just make sure you update it before running.

If it takes a few days then that's what it takes.

Just post back here and I'll be sure to look at it.
