The delete this file:

C:\WINDOWS\SYSTEM\DBDI.DLL



Then delete all yout Temp files, its easyer to use ccleaner for this (free), you can get it from here: http://www.filehippo.com/download_ccleaner.html

Then go to windows update and install all critical updates (www.windowsupdate.com).

Then reboot your machine, redo and repost your hijackthis log so we can confirm your system is clean.

Lee ,I will follow your instructions, Though I have a question, As I have been tracing this down one of the things I did after running avast anti virus The trojan file  wouldn't be sent to virus chest(Access denied can't process) so I followed instructions to copy to the user file in the virus chest. that happened ok. Shoul i have gone back to the original location the virus was discovered and deleted it there? thans again Jim

[lee16]

The trojan file  wouldn't be sent to virus chest(Access denied can't process)

Thats basicly because the malware was still activated, so do as suggested above, then run CWshredder as as said on the other thread, then the problem should be gone, however if its not, then open taskmanager (Alt + Ctrl + del) and kill all processes apart from Explorer and Systray, then try again with avast.

--lee

[DavidR]

I don't think that there are any CoolWebSearch hijacks here, but running CW Shredder (from your other thread) won't hurt.

If you haven't already got these, download, install and run them.

1. Ad-Aware
2. Spybot Search and Destroy
3. Spywareblaster

[lee16]

If you haven't already got these, download, install and run them.

1. Ad-Aware
2. Spybot Search and Destroy
3. Spywareblaster

Don't forget to update them first 

--lee

[jbbigq]

Ok here is what I've done so far
removed items via hijack this as instructed
ran cleensweep ok
deleted windows\system\dbdi.dll  although I had to reboot computer before it would let me because it was using it at the time .
could not update windows ( I keep getting this persistent spyware that pops up during (Funny the popup is telling me I have spyware and  I assume will redirect me if I  click on it) One time while the popup was on my computer I logged off of aol leaving the aol program on then clicked on the ok sign and a website address showed in the address bar at the top of the aol screen. I don't know if that address would be any help in all this. but i copied it to notepad on my desktop and have access to it.
 
After this I will run both spybot search and destroy and ad-aware current updates.
  In the current hijack this file it still shows a reference to 1 of the trojans I noticed earlier(trojan found windows\temp\se.dll)

Thanks for the tip on the anlysis tool @hijack this.   He gave me some things to check.ie  C:\PROGRAM FILES\ALWIL SOFTWARE\AVAST4\ASHMAISV.EXE   
Safe.   running process. (ASHMAISV.EXE)
   
Possibly nasty! According to our database this process runs normally in c:\programme\alwil software\avast4\! Check if you know this process and arrange a viruscheck
. If i find this file in the proper place is it ok to just delete  the one in the program files?

[jbbigq]

Oh And I know i'm running an older version of internet explorer I tried to get the update from windows update but it won't finish loading and installing . Is there some other way to get the update.
Also any suggestions on firewall for this old computer?

Leave it in place this is a bug with the latest version of hijackthis, if you remove this registry key Mail Shield won't run at start-up.

I think you can only update to IE6 SP1 with win98 (IE6 SP2 is XP only), you may find it on a Computer Magazine CD or ask a friend to download it for you.

A search of google returns many options - http://www.google.co.uk/search?q=Microsoft+IE6+SP1+download - http://www.microsoft.com/windows/ie/downloads/critical/ie6sp1/default.mspx this is one of them, you can download it outside of windows update and update off-line.

There are many different threads relating to firewalls a forum search will return many hits. However, Zone Alarm (free) has a more user friendly interface for the novice firewall user.
