When I try to delete dllhost.exe on XP it won't allow me. It allowed to delete Ms_BLAST.exe but not the other one. Any idea how to get rid of it. My anti-virus detects it's a virus but won't clean and when I try to manually, it won't let me. When I try to go the registry, the window comes up for 5 seconds and goes away. Same thing with the processes tab. THe computer is no longer shutting down bc I deleted MS_Blast.exe but it is still not 100% clean. HELP!

Find what DLLHOST.exe is, on this web page: http://www.answersthatwork.com/Tasklist_pages/tasklist_d.htm It is a Microsoft file.

The system dllhosts file resides in system32, ur'll find the infected one is in C:\WINDOWS\system32\wins folder !! If u open task manager, u will find it running, but u wont be able to shut it down !! Just re-start in safe mode and u can safely delete it. Hope this helps

seems like you catched the Welchia virus, refer to http://www.bitdefender.com/html/virusinfo.php?menu_id=1&v_id=151 or http://www.pchell.com/virus/welchia.shtml if you are fond with windows you can follow the instructions and remove it manually, otherwise get the appropriate remover (check the links). i wouldn't just delete the file but it probably does the job as well, yet not very properly. make sure however you install the patch

This is a worm called w32.welchia.worm. I found this proggy trying to connect to the internet when zonealarm alerted me about it on my client's Win2kProf. I seemed to try and connect to every address in the range 192.168.y.z. Couldnt kill it with task manager so i searched the registry and found that it was loading up as a service called "Wins Client". I stopped the service using service manager, disabled it, used the NT Resource kit to un-install the service and everything seemed to work fine after rebooting. Note that i am still able to use the internet and browse all the other machines on the lan with this system, so I dont think it was a valid windows program.

I run into the same problem with Win2000. when I tried to remove dllhost.exe and csvhost.exe svchost.exe from the c:\windows\system32\wins directory. But I was able to rename them to different file name (arbitrary). Then restart the computer. After the computer is restarted, I was able to remove the renamed virus file.

I came across this board because I was searching for some info on "dllhost.exe" the reason is because recently my computer has been infected with a lot of weird files so I have to check the Task Manager regularly and this time I saw 2 "dllhost.exe", 1 is SYSTEM and the other is IWAM_[mycomputer'sname], it looks really suspicious cuz I've never seen this before in Task Manager... I've read some threads saying that the infected files is in /System32/Wins/ but when I go there, there's no file in that folder, the only 1 "dllhost.exe" I found after doing a search is in the system32 folder and its size is 5kb and the name is lowercase, oh and 2 other .pf files in the windows/prefetch folder... So I'm wondering if my computer is infected with this virus that's been talked about or what? Thanks a lot for your attention!!!
