Am writing from another computer than the one infected. Am afraid to do much with the infected one until this problem is solved. Looked at initial help in START HERE and did/verified the following:

1) ran SPYBOT S & D which is already installed, but was afraid to update via the internet due to existing infection

2) ran AVG scan with most recent updates imported from this computer

3) it seems that SP2 is NOT installed, but the update file is huge and this is Romania -- we only have slow dial-up -- and I'm afraid of getting another infection during the time it is connected...what should I do?

4) rebooted

message continues to appear from AVG every few minutes regarding the following file being infected with the collected.5.l trojan horse:

c:\documents and settings\[user name]\msdirectx.sys

keep deleting it and after a minute or so it comes back

Thanks in advance for your help.

Thank you so far. Did all that you instructed, but hit a snag in the KILLBOX step.

1) After answering REBOOT on the second file, it waited a little while, then gave the message: "PendingFileRenameOperation Registry Data has been removed by External Process!"

2) I clicked OK and went ahead and REBOOTED manually into SAFE MODE and performed the remaining instructions as given in your last message.

3) After the final REBOOT, the problem seemed to go away, but after starting an AVG scan again it found the same file infected as before: c:\documents and settings\[user name]\msdirectx.sys

4) A new version of HJT is below. I'm not sure what to do next.

You did good sofar :tazz:

Please disable SpybotSD’s protection, as it may hinder the removal of the infection. You can enable it after you're clean.

Open Spybot and click on Mode and check Advanced Mode
Check yes to next window.
Click on Tools in bottom left hand corner.
Click on Resident icon.
Uncheck Teatimer box and/or Uncheck Resident.
Click Allow Change box.

***

Double-click Killbox.exe to run it.

Select "Delete on Reboot".
Place the following line (complete path) in bold in the "Full Path of File to Delete" box in Killbox:
C:\WINDOWS\System32\xpjava.exe
Put a mark next to "Delete on Reboot"
Click the red-and-white "Delete File" button. Click "Yes" at the Delete on Reboot prompt. Click "No" at the Pending Operations prompt.
If your computer does not restart automatically, please restart it manually.

***

Please rerun unlegacy.reg

Reboot and tell me how things are now.

THANK YOU!!!!

Looks like it worked. AVG looks clean so far, but it takes about 45 minutes to do the complete scan -- however, it is past the system folders already.

At any rate, there are several questions that remain:

1) It appears that someone else was using the system on the internet and said OK to something coming in that KERIO had stopped. If we are more careful in the future, will the KERIO FIREWALL protect against such problems?

2) Is the answer to number 1 dependent on whether we update to XP SP2 or not?

3) How does the donation process work? I have PayPal and would like to make a donation but cannot do so via any automated link since I am in Romania. Is there an e-mail address I can send something to directly?

Thanks again! I will tell my friends about this service.

Kerio is protecting you already. As you said, that someone choose to overwrite kerio's protection.
You will definitly be better protected once you applied all the updates for Microsoft.
I will also post you some tips for the future.

Let's wait till AVG is done scanning. If you tell me it's clean, I will post you the tips and close the topic.

AVG scan finished clean and ran about twice as fast. Trying a number of programs we use often, but staying away from the internet until we check it out thoroughly. Thanks again. Look forward to your tips...

please follow these simple steps in order to keep your computer clean and secure:
  • Disable and Enable System Restore. - If you are using Windows ME or XP then you should disable and reenable system restore to make sure there are no infected files found in a restore point.

    You can find instructions on how to enable and reenable system restore here:

    Managing Windows Millenium System Restore

    or

    Windows XP System Restore Guide

    Renable system restore with instructions from tutorial above

  • Make your Internet Explorer more secure - This can be done by following these simple instructions:
    • From within Internet Explorer click on the Tools menu and then click on Options.
    • Click once on the Security tab
    • Click once on the Internet icon so it becomes highlighted.
    • Click once on the Custom Level button.
      • Change the Download signed ActiveX controls to Prompt
      • Change the Download unsigned ActiveX controls to Disable
      • Change the Initialize and script ActiveX controls not marked as safe to Disable
      • Change the Installation of desktop items to Prompt
      • Change the Launching programs and files in an IFRAME to Prompt
      • Change the Navigate sub-frames across different domains to Prompt
      • When all these settings have been made, click on the OK button.
      • If it prompts you as to whether or not you want to save the settings, press the Yes button.
    • Next press the Apply button and then the OK to exit the Internet Properties page.
  • Use an AntiVirus Software - It is very important that your computer has an anti-virus software running on your machine. This alone can save you a lot of trouble with malware in the future.

    See this link for a listing of some online & their stand-alone antivirus programs:

    Virus, Spyware, and Malware Protection and Removal Resources

  • Update your AntiVirus Software - It is imperitive that you update your Antivirus software at least once a week (Even more if you wish). If you do not update your antivirus software then it will not be able to catch any of the new variants that may come out.

  • Use a Firewall - I can not stress how important it is that you use a Firewall on your computer. Without a firewall your computer is succeptible to being hacked and taken over. I am very serious about this and see it happen almost every day with my clients. Simply using a Firewall in its default configuration can lower your risk greatly.

    For a tutorial on Firewalls and a listing of some available ones see the link below:

    Understanding and Using Firewalls

  • Visit Microsoft's Windows Update Site Frequently - It is important that you visit http://www.windowsupdate.com regularly. This will ensure your computer has always the latest security updates available installed on your computer. If there are new updates to install, install them immediately, reboot your computer, and revisit the site until there are no more critical updates.

  • Install Spybot - Search and Destroy - Install and download Spybot - Search and Destroy with its TeaTimer option. This will provide realtime spyware & hijacker protection on your computer alongside your virus protection. You should also scan your computer with program on a regular basis just as you would an antivirus software.

    A tutorial on installing & using this product can be found here:

    Using Spybot - Search & Destroy to remove Spyware , Malware, and Hijackers

  • Install Ad-Aware - Install and download Ad-Aware. ou should also scan your computer with program on a regular basis just as you would an antivirus software in conjunction with Spybot.

    A tutorial on installing & using this product can be found here:

    Using Ad-aware to remove Spyware, Malware, & Hijackers from Your Computer

  • Install SpywareBlaster - SpywareBlaster will added a large list of programs and sites into your Internet Explorer settings that will protect you from running and downloading known malicious programs.

    A tutorial on installing & using this product can be found here:

    Using SpywareBlaster to protect your computer from Spyware and Malware

  • Update all these programs regularly - Make sure you update all the programs I have listed regularly. Without regular updates you WILL NOT be protected when new malicious programs are released.
Follow this list and your potential for being infected again will reduce dramatically.

Glad I was able to help.
