Hi mate. I'm relatively new to all this but I noticed your log has a similar entry to mine. See the thread here. http://forums.spywar...t=0

I'm going through both HJT logs to (hopefully) eliminate safe entries.

I did find that DSB.exe is listed as Adware by Symantec. Removal instructions available here.


I'll keep you posted if I find anything else. Cheers.

Great to hear from someone with a similar problem John, any help is greatly appreciated.

Will have a go at removing DSB.exe as you have suggested.

What i thought was strange was the fact that HJT found the file with the virus C:\WINDOWS\System32\winbjoi.dll but would'nt allow me to remove it. :scratchhead:

Anyway, if you have any success please let me know,

Hope to hear again soon :whistle:

John, I've noticed a similar number of people have the same problem, (do a search for topics mentioning *.dll in the title).

If you go to this thread

you'll find it is a known issue. Freeatlast gives full instructions for the removal of the file.

Good luck,

WOW!! :D

I think it has gone, I followed the procedures to the letter, then when I re-booted a Norton box popped up with a different Trojan found.

However, after trying the same removal process again I couldnt get past the point where i had to find the file in the Windows directory, it simply was not there. I then re-booted the system and no virus box came up. I scanned the hard drive with Norton, it picked up the original 'winbjoi.dll' trojan but this time quarantined and removed it.

After that the system was running fine, no about:blank, pop-ups or viruses found by Norton. The only thing that still didnt work properly was that the other user account (my girlfriends) on my Dell PC crashes upon opening up, to remedy this I have created a third account which she will now have to use instead. Also, Yahoo companion (which always used to bring up the about:blank page when activated) can still not be removed from the programs.

Still, the trojan certainly looks like it has gone for now

Many thanks for your help Johnjb
