Unidentified malware on Admin user account

Hi.

Before we proceed any further please post the contents of the ComboFix log. It can be located here:-

C:\ComboFix

[helpintoledo]

There is no log file present at the root or elsewhere. Interestingly, there is a file, of file type "File" named ComboFix at C:\Combofix. However, in windows it merely acts as a UNIX style Symlink back to C:\ and cause therefore a recursive loop when doing a search for ComboFix in the windows search utility. At a command prompt however, if I cd C:\Combofix and dir, I get what appears to be a listing of the combofix inner workings. But no log. Attached is a picture of the Windows search output.

fyi, dir command in "C:\" lists "\ComboFix\" as [DIR] file type

Hi.

Nothing is easy with this particular machine!

OK levity aside, do you have the Vista DVD? As we may very well need this.

Backup the Registry:

Modifying the Registry can create unforeseen problems, so it always wise to create a backup before doing so.

Please navigate to Start >> All Programs >> ERUNT >> Right-click on ERUNT and select Run as Administrator.

• Click on OK within the pop-up menu.
• In the next menu under C:\WINDOWS\ERDNT\DD-MM-YYYY under Backup options make sure both the following are selected:
• System registry
• Current user registry
• Next click on OK
• When the Question pop-up appears click on Yes
• After a short duration the Registry backup is complete! popup will appear
• Now click on OK. A backup has been created.

Note: If you have uninstalled ERUNT since we last used it, please inform myself before proceeding any further.

Reset Vista SP2 Firewall:

Click on Start(Vista Orb) >> Run...(or the Windows key and R together) to bring up the Run box and cut/paste in the following and click on OK

Code: Select all

firewall.cpl

Or Start(Vista Orb) >> Control Panel >> Windows Firewall

Click on the Change Settings >> Advanced >> Restore Defaults >> At the prompt click on Yes >> OK

Now click back on Change Settings again >> General >> and select On(recommended) >> Apply >> OK.

Dakeyras, I would like to thank you for all your help in this matter. Unfortunately, the owner of the pc has taken it back, for better or worse (for what it's worth his wife reports it is working just fine, however long that may last). I really would have liked to have seen this through to a proper completion, but he decided he needed access to his computer for a couple reasons. I really dislike not being able to defeat something like this, but please know I am fully aware that you gave all the help that you could, especially considering my schedule. Please feel free to close this thread. Thanks again and take care.

OK, you're welcome and thank you for the courtesy of informing myself. Not a ideal situation and it would have been far better if your friend had exhibited some patience and let us see the malware removal process through.............However I will respect the decision as the machine in question is their property after all.
