I am running Vista on a Dell Inspiron 1720 IE8

 

This morning AVG detected a Win32/patched virus in 4 locations.  That spread to 8 location fairly quickly.

 

   C;\windows/system32\svchost.exe

   C:\program files\saitek\sd6\software\profileru.exe

   c:\program files\yahoo!\messenger\yahoomessenger.exe

   c:\windows\system32\verclsid.exe

   c:\program files\adobe\reader9.0\reader\reader_st.exe

 

 

Another strange symptom is that I can hear ads running but no indication of where they are coming from, nothing was opened at that time.  

 

AVG says that it cannot delete the files. the AVG code is 0xA001F803

 

What can I do to get rid of this stuff?

 

Thanks,

wgb

Hi,
 
Please download Rkill (courtesy of BleepingComputer.com) to your desktop.
There are 2 different versions. If one of them won't run then download and try to run the other one.
You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.
 
rKill.exehttp://www.bleepingcomputer.com/download/rkill/dl/10/
iExplore.exe (renamed rKill.exe): http://www.bleepingcomputer.com/download/rkill/dl/11/

  • Double-click on the Rkill desktop icon to run the tool.
  • If using Vista or Windows 7 right-click on it and choose  Run As Administrator.
  • black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
  • If not, delete the file, then download and use the one provided in Link 2.
  • Do not reboot until instructed.
  • If the tool does not run from any of the links provided, please let me know.

You should see a text file on your desktop named Rkill.txt, please copy and paste that into your next reply.

Hi,

 

Whoops, we cross-posted.

 

You got hit with the latest version of Zekos. One of your system files (rpcss.dll) has been patched.
You'll need more advanced tools to replace that file.
 
Please follow the instructions in THIS GUIDE starting at Step 6. If you cannot complete a step, skip it and continue.

Once the proper logs are created, then make a NEW TOPIC and post it HERE. Please include a description of your computer issues, what you have done to resolve them, and a link to this topic.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

It would be helpful if you post a note here once you have completed the steps in the guide and have started your topic in malware removal. Good luck and be patient.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/522626/win32patched-virus-infection-on-vista-system/ 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 MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in 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 MRT 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 MRT Team members are EXTREMELY 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 MRT 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 MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.

To avoid confusion, I am closing this topic. Good luck with your log.
