Looks like the scan came back clean. Do you recall what ESET detected earlier? If not, then maybe try to scan again.

Yeah, too bad your team let him leave for Leverkusen

hi Blade,

the ESET scan definitely confirmed there was an infected object and if I recall referred to it as a variant of the winsystem32 trojan. Unfortunatley, it did not log it. To be sure, I'll arrange a further scan when I get home later

As regard to getting rid of Sami - we need him back desperately

I will revert to you just as soon as further scan is complete

Thanks
Tom

Ok. Shall wait for your report

Hi Blade,

Just running the ESET report. It is reporting 1 infected file. Threat found - probably a variant of Win32/Agent Trojan.

I'll post the log when finished but presume it will be similar to the last occassion

Thanks
Tom

Hi Blade,

There was one infected file. The log didnt save again however, I was able to save my own txt file which is posted below:

C:\Program Files\Sports Interactive\Football Manager 2009\fm91_t1.exe probably a variant of Win32/Agent trojan

Thanks
Tom

Hi,

Is that original copy of Football Manager 2009 you have installed there? If it is, then finding is most likely a false positive.

Hi Blade,

My lad has confirmed he installed it early in the year (its not now used and has been removed)

However, I certainly did not purchase it for him so have quizzed him as to whether it was an original copy. He assures me that it was but suggests that it was borrowed from a friend!! - In light of the apparent infection, I'm not convinced and have a worrying feeling he is not being entirely honest.

Sorry I cannot be more specific Blade - can you confirm the best way forward?

Thanks
Tom

Hi,

If I understood right you removed it so no further action is needed.

I think it's time for the final steps if there're no other problems


THESE STEPS ARE VERY IMPORTANT

Let's reset system restore
Reset and Re-enable your System Restore to remove infected files that have been backed up by Windows. The files in System Restore are protected to prevent any programs changing those files. This is the only way to clean these files: You will lose all previous restore points which are likely to be infected. Please note you need Administrator Access to do clean the restore points.

A To disable the System Restore feature:

1. Click on the Start button.
2. Hover over the Computer option, right click on it and then click Properties.
3. On the left hand side, click Advanced Settings.
4. If asked to permit the action, click on Allow.
5. Click on the System Protection tab.
6. Uncheck any checkboxes listed for your hard drives.
7. Press OK.


B. Reboot.

C Turn ON System Restore.
Follow the steps like you did when disabling system restore but on step 6. check any checkboxes listed for your hard drives.




Now lets uninstall ComboFix:

• Click START then RUN
• Now copy-paste Combofix /u in the runbox and click OK

Please download OTC and save it to desktop.

• Double-click OTC.exe.
• Click the CleanUp! button.
• Select Yes when the
  Begin cleanup Process?
  prompt appears.
• If you are prompted to Reboot during the cleanup, select Yes.
• The tool will delete itself once it finishes, if not delete it by yourself.

Note: If you receive a warning from your firewall or other security programs regarding OTC attempting to contact the internet, please allow it to do so.


UPDATING WINDOWS AND INTERNET EXPLORER

IMPORTANT: You Need to Update Windows and Internet Explorer to protect your computer from the malware that is around on the Internet. Please go to the windows update site to get the critical updates.

If you are running Microsoft Office, or any portion thereof, go to the Microsoft's Office Update site and make sure you have at least all the critical updates installed (Free) Microsoft Office Update.

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.



The following are recommended third party programs that are designed to keep your computer clean. A link as well as a brief description is included with each item.

• hosts file:
  
  • Every version of windows has a hosts file as part of them.
  • In a very basic sense, they are used to locate webpages.
  • We can customize a hosts file so that it blocks certain webpages.
  • However, it can slow down certain computers.
  • This is why using a hosts file is optional!!
  
  Download it here. Make sure you read the instructions on how to install the hosts file. There is a good tutorial here
  If you decide to download the hosts file, the slowdown problems can usually be avoided by following these steps:
  
  2. Click the start button (at the lower left hand corner of your screen)
  3. Click run
  4. In the dialog box, type services.msc
  5. hit enter, then locate dns client
  6. Highlight it, then double-click it.
  7. On the dropdown box, change the setting from automatic to manual.
  8. Click ok

Just a final reminder for you. I am trying to stress these two points.
UPDATE UPDATE UPDATE!!! Make sure you do this about every 1-2 weeks.
Make sure all of your security programs are up to date.
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.


Once again, please post and tell me how things are going with your system... problems etc.

Have a great day,
Blade
