Hi all,

Yesterday Avast popped up to warn that svchost.exe was some kind of trojan or virus. So I clicked the option to delete the files and moved on.
Later I restarted the pc and my new windows xp prof install was damaged: no avast nor ad aware icons in the sys tray. No network connections: no internet browsing. The network connections list is empty.

So I started the pc with a win vista install on another disk. The avast scan found:
25/07/2009 2:04:57 1964 Sign of "Win32:Bifrose-EGW [Trj]" has been found in "D:\WINDOWS\Installer\af3198.msp" file.

After the cleaning I tried to run Malwarebytes AM on the xp install to see if it would pick up any virus that may have re-activated but now got a Runtime Error 372
"Failed to Load Control 'VbalGrid' from vbalsgrid.ocx. Your version of vbalsgrid.ocx may be outdated. Make sure you are using the version of the control that was provided with your application".

Still no avast nor ad aware icons in the sys tray. No network connections: no internet browsing. The log events in computer mngt don’t pop up on double click.
there's more wrong but decided to surf the net for info and stopped here :thumbup2:
the hjt log hasnt been made yet.


update:
* false positive?? http://forum.avast.com/index.php?PHPSESSID...;topic=47063.30
* hjt logs added
* safe mode with networking works,
* regedit works, but still no network connection


update 2 : sysprot log added

update 3:
help fnc is not working,
props of services in services.msc gives error dependencies not found or marked for deletion,
sys restore rstrui.exe also gives an error, as well in safe mode
the sys restore tool rsdiag produces a list with 30 entries till 24/7, all with a "valid" mark
(so is there a way to force a restore on one of those points?)

Update for 26/07/2009

>Basically I believe what should be done is to let all necessary services -that no longer start up - start up at boot and repair missing dependencies which aren’t solved by the started services. <


Actions performed the last 24 hours:
The Avast and MBAM scans have scanned and cleaned my disks.
In the Avast log I found “win32:rootkit-gen found in svchost.exe”, thus it was deleted as I had confirmed the “delete tread?” of the Avast pop up. After reboot this must have been causing several problems like services that no longer start up at boot and missing dependencies. Indeed there was no longer svchost.exe in \\ windows\system32 , so I copied it back.

Unfortunately this sole action doesn’t make my pc work normally. So I think disabled services like the RPC must get working again.
I tried c:\\windows\system32\svchost –k rpcss, which started svchost and the process appeared in the task manager for 10 seconds, and then it disappeared.

In order the try regain network functionality I registered some dll successfully.
regsvr32 netcfgx.dll
regsvr32 netshell.dll
regsvr32 netman.dll
But network connections list is still empty.

Hello b0gb0g,

We ask that once you have posted your log and are waiting, please DO NOT "bump" your thread or make further replies until it has been responded to by a member of the HJT Team. The reason we ask this or do not respond to your requests is because that would remove you from the active queue that Techs and Staff have access to. The malware staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response, there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

That is why I have made an edit to your last post, instead of a reply. Please do not multiple post here, as that only pushes you further down the queue and causes confusion to the staff.

Please be patient. It may take a while to get a response but your log will be reviewed and answered as soon as possible.

Thank you for understanding.

Regards,

The weatherman
