Hi,

I would be grateful for any help regarding a possible rogue instance of svchost.exe.

Windows XP SP3 / IE7 / Firefox

I have a "standalone" instance of SVCHOST.EXE which I am concerned about, as both IE 7 and Firefox are constantly being redirected, and many services - including Windows Firewall - are often stopped without warning or notice.

However, AVG 9.0 Free and Malwarebytes' Anti-Malware both give my computer the all clear, and HijackThis doesn't list anything that I don't recognise.

==================================================

Point 1.

Process Explorer shows the following details (Image tab) about this particular svchost.exe:

"C:\WINDOWS\system32\svchost.exe" (no command options)
Parent: <Non-existent Process>
User: MyComputer\MyUserName
Virtual size 39,272 K

PE verifies this host as "(Verified) Microsoft Windows Component Publisher."

However, with no command line options and no parent and child processes, this host looks very suspect.

(In fact, this svchost.exe is outside the "System Idle Process" tree altogether.)

--------------------

Point 2.

Process Explorer shows the web address (TCP/IP tab) being used by this instance of svchost.exe as:

"Remote Address: srv169.cyberhost.name:http"

Is this a bona fide address for Windows XP to be using as part of its operating system?

--------------------

Point 3.

There are 4 normal instances of svchost.exe, all of which seem valid:

Parent: services.exe
User: NT AUTHORITY\SYSTEM or NT AUTHORITY\NETWORK SERVICE

These 4 instances account for all the 18 services I have running (split 15 + 1 + 1 + 1).

Therefore, the "stand-alone" instance of svchost.exe looks even more suspect as none of the services that are listed as "started" in "services.msc" console are missing.

--------------------

Point 4.

I suspended the svchost.exe in Process Explorer, and everything seems to be working ok.

--------------------

So, is this SVCHOST.EXE rogue??

==================================================

Also, any ideas on the following two issues?

--------------------

Point 5.

Yesterday, two suspicious "Browser Helper Objects" appeared in the IE Manage Add-ons, namely:

{7E853D72-626A-48EC-A868-BA8D5E23E045} and {BDC8AC54-D303-4BF5-8C0E-B4A3A0CE7E53}.

They had no names or information about them, and so I deleted them.

--------------------

Point 6.

I have a locked temporary file being created each boot-up in the "%homepath%\Local Settings\Temp" directory which I cannot delete - an error message "Access is denied" comes up.

It always has the name "in#.tmp", where # is a number (e.g. "in5.tmp").

It is only 3 KB in size.

Although the characters in the file are non-ascii, each file has the string "http://nafnafqchgoogle.com/vodkaspasetmir/gwefeweterfreferger.php?id=e830cddd" in it, as well as some internet related calls e.g. "InternetOpenA InternetConnectA HttpOpenRequestA HttpSendRequestA".

==================================================

Any help would be much appreciated as I have spent too many hours trying to resolve these problems!

Kind regards,
Andy

Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the 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 Malware Removal Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic.
