An W2K Pro laptop that has an up to date NAV running. Double-checked with Trends Sysclean and okay.

The default home page is being switched with "about:blank" in the addressbar and something is causing a crash on a critical business web page (perhaps a page with an ActiveX control).

Spybot, Ad-aware, and CSshreder all found items to remove. Double-checked on Hijack This afterwards and could not find any entries that were not legite. Used Hijack This to reset the default pages.

System worked fine for a couple of hours, then problem resurfaced. The new Hijack This log reveals a new O18 entry that I cannot find in any Google searches:

O18 - Filter: text/html - {5769DEE5-E0FA-4CB2-9849-D54149EEF3FD} - C:\WINNT\system32\dbcb.dll
O18 - Filter: text/plain - {5769DEE5-E0FA-4CB2-9849-D54149EEF3FD} - C:\WINNT\system32\dbcb.dll

Have I found something new and if so, how do I "report it"?

Please do the following:

Download the program FindNFix from the following location:


Once it is downloaded, double-click on the file to run it. Follow the prompts to install the program. Once it is installed a window will open up showing the installation directory and a bunch of files in the right section of the window.

On the right portion of the window look for the file called !LOG!.bat and double-click on it. It will scan through your computer for a while, so be patient. When it is completed it will automatically open a notepad window called Log.txt.

Copy the contents of that file into a reply to this post.

Thanks for offering to help, but after making the post, I did some research on the "about:blank" aspect of the malware and came across this explaination and instructions:


Since the system looks like it's cleaned up, I'll have to try your advice next time.

You may want to post your log any way to make sure. There was stuff in there that this procedure will not fix.
