Re: HELP!!! - Please help to remove Trojan.Win32.Delf.bon

Hi,

We need to manually remove the file 'C:\Program Files\ Internet Explorer\svchost.exe' and it's associated registry entries. Can you download Hijackthis, run it and post the log file here.

Re: HELP!!! - Please help to remove Trojan.Win32.Delf.bon

On a second thought, you can give a quick try to manually remove this virus. Please follow the below instructions:

1. Reboot your computer, Keep pressing F8 to enter safe mode.

2. Login as any Admin user and delete the file:

Quote:
'C:\Program Files\Internet Explorer\svchost.exe'
3. No Start and type in 'regedit' in search box to open registry editor. Now find and select the following entries.

Quote:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
Svchost
C:\Program Files\Internet Explorer\svchost.exe

HKLM\Software\Microsoft\Windows\CurrentVersion\Run Once
Svchost
C:\Program Files\Internet Explorer\svchost.exe

HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Svchost
C:\Program Files\Internet Explorer\svchost.exe

HKCU\Software\Microsoft\Windows\CurrentVersion\Run Once
Svchost
C:\Program Files\Internet Explorer\svchost.exe
HKLM : HKEY_LOCAL_MACHINE
HKCU : HKEY_CURRENT_USER


4. Reboot in normal mode.

I still doubt the file is present. It may be hidden. Is your 'show hidden files' and 'system file' options enabled?

You can try the following command to remove the hidden and system attributes of the file. Check it in safe mode.

Quote:
attrib -h -s "C:\Program Files\Internet Explorer\svchost.exe"
If it's showing file not found then we can confirm it's not the issue.

In addition to this download Spybot - Search & Destroy and do a scan.

http://www.safer-networking.org/en/download/index.html

I also recommend installing a Firewall like ZoneAlarm free, in Interactive mode, to keep track of the programs using your internet connection.

hmm... atm... ive downloaded spybot and scanned it first.... it comes up with 3 problems...

they all are registry changes and all of them are HKEY-USERSS and Spybot mentions that they are all to do with Microsoft Internet Explorer...

EDIT: also on spybot it says that the three problems are adware...

Company: -
Product: ShowBehind
Threat: Adware

by the way.... wont the zone alarm firewall conflict with my kaspersky firewall or my windows vista firewall im currently using the kaspersky firewall

OKAY!! this is getting out of hand.... it seems Spybot found the THREE trojans... all in the same place... it fixed the problems or so i thought... until Kaspersky popped up saying that the location of ShowBehind was password protected... so the three threats are showing on kaspersky still and again on Spybot....

man this is stuffed bad

Hey strider... ive tried all those methods including the safe mode one... the file can be found however im still getting the problem from kaspersky saying

Trojan Program:
Trojan.Win32.Delf.bon

Running module:
C:\Program Files\Internet Explorer\svchost.exe

Re: Help to remove Trojan.Win32.Delf.bon -C:\Program Files\Internet Explorer\svchost.exe

Download KillBox. browse and select that file, and choose to Delete on reboot.

then perform a reboot.

or you can open services.msc, find the service Window Net Dns (MyDNS) and set it to disabled. then stop the service and delete the file. Note down the service name, open command prompt and type :
sc delete <service name>

And DISABLE system restore and run a scan. And yes, having more firewalls will conflict. Disable the Vista firewall if you use the one from Kaspersky or ZoneAlarm.

Did you disable System restore and run the scan ?

Also run a full system scan on all the partitions.
