Hi there,

Every time i connect to the internet, I have svchos1at.exe showing up in Norton as a threat(Trojan horse) but it couldn't access or delete the file. It also have a runtime error 2 at 0040529A showing up.


I can't get rid of the file even with the system restore disabled using adaware in safe mode. I also ran ad-aware and hijackthis.

At the moment it doesn't really affect my computer except the Norton message prompting every so often that there is a virvus.

Can someone help me to get rid of this...i am at a lost as to what to do.

I am running Windows XP with all the latest Norton updates.


The log that came up with Hijack this was as below. Many thanks!

Hello stellarl and welcome to the BC forums. After reviewing your log I see a few items that require our attention. Please print these directions and then proceed with the following steps in order.

Step #1

Download CCleaner and install it but do not run it yet.

Step #2

Start in Safe Mode Using the F8 method:
  • Restart the computer.
  • As soon as the BIOS is loaded begin tapping the F8 key until the boot menu appears.
  • Use the arrow keys to select the Safe Mode menu item.
  • Press the Enter key.
Step #3

Start HijackThis and click the Scan button to perform a scan. Look for the following items and click in the checkbox in front of each item to select it:R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Bar = http://uk.red.clientapps.yahoo.com/customi...fo/bt_side.html
R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = http://uk.red.clientapps.yahoo.com/customi...arch.yahoo.com/
R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Search_URL = http://uk.red.clientapps.yahoo.com/customi...arch.yahoo.com/
R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Search Bar = http://uk.red.clientapps.yahoo.com/customi...fo/bt_side.html
R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Search Page = http://uk.red.clientapps.yahoo.com/customi...arch.yahoo.com/
R1 - HKCU\Software\Microsoft\Internet Explorer\SearchURL,(Default) = http://uk.red.clientapps.yahoo.com/customi...arch.yahoo.com/
O4 - HKLM\..\Run: [HDAudio Driver] C:\WINDOWS\system32\kfcozde.exe
O4 - HKLM\..\Run: [antivirus] C:\WINDOWS\timer.exe /i

Now close ALL open windows except HijackThis and click the Fix Checked button to finish the repair.

Step #4

We need to make sure all hidden files are showing so please:
  • Click Start.
  • Open My Computer.
  • Select the Tools menu and click Folder Options.
  • Select the View tab.
  • Under the Hidden files and folders heading select Show hidden files and folders.
  • Uncheck the Hide file extensions for known types option.
  • Uncheck the Hide protected operating system files (recommended) option.
  • Click Yes to confirm.
  • Click OK.
Find the following files/folders and delete them (don't worry if they are already gone):C:\WINDOWS\system32\kfcozde.exe
C:\WINDOWS\timer.exe

Step #5

Start CCleaner and click on the Run Cleaner button in the lower right-hand corner. When it is finished close CCleaner.

Step #6

Reboot normally and run at least 2 of the following on-line virus scans:Trend Micro Housecall
BitDefender On-Line Virus Scan
Panda ActiveScan
eTrust Antivirus Web Scanner
Make sure that you choose "fix", "clean" or "autoclean". If you have any files that cannot be disinfected or quarantined automatically then you will need to delete them manually.

Step #7

AdAware SE v1.06

Download, install, update, configure and run a scan with Ad-aware SE v1.06:
  • Download and Install AdAware SE Personal, keeping the default options. However, some of the settings will need to be changed before your first scan.
  • Close ALL windows except Ad-Aware SE.
  • Click on the‘world’ icon at the top right of the Ad-Aware SE window and let AdAware SE update the reference list for the adware and malware.
  • Once the update is finished click on the ‘Gear’ icon (second from the left at the top of the window) to access the preferences/settings window:
    • In the ‘General’ window make sure the following are selected in green:
      • Under Safety:
        • Automatically save log-file
      • Automatically quarantine objects prior to removal
      • Safe Mode (always request confirmation)
    • Under Definitions:
      • Prompt to update outdated definitions - set the number of days
  • Click on the ‘Scanning’ button on the left and select in green:
    • Under Driver, Folders & Files:
      • Scan Within Archives
    • Under Select drives & folders to scan:
      • choose all hard drives
    • Under Memory & Registry: all green
      • Scan Active Processes
      • Scan Registry
      • Deep Scan Registry
      • Scan my IE favorites for banned URL’s
      • Scan my Hosts file
  • Click on the ‘Advanced’ button on the left and select in green:
    • Under Shell Integration:
      • Move deleted files to recycle bin
    • Under Logfile Detail Level: all green
      • include addtional object information
      • DESELECT - include negligible objects information
      • include environment information
    • Under Alternate Data Streams:
      • Don't log streams smaller than 0 bytes
      • Don't log ADS with the following names: CA_INOCULATEIT
  • Click the ‘Tweak’ button and select in green:
    • Under ‘Scanning Engine’:
      • Unload recognized processes during scanning
      • Scan registry for all users instead of current user only
    • Under ‘Cleaning Engine’:
      • Let Windows remove files in use at next reboot
    • Under Log Files:
      • Include basic Ad-aware SE settings in logfile
      • Include additional Ad-aware SE settings in logfile
      • Please do not check: Include Module list in logfile
  • Click on ‘Proceed’ to save the settings.
  • Click ‘Start’
  • Choose 'Perform Full System Scan'
  • DESELECT "Search for negligible risk entries", as negligible risk entries (MRU's) are not considered to be a threat.
  • Click ‘Next’ and Ad-Aware SE will scan your hard drive(s) with the options you have selected and clean automatically.
  • If Ad-Aware SE finds bad entries, you will receive a list of what it found in the window
  • Right-click on the list and choose Select All
  • Click the Next button to finish removing the items that were found
  • When finished, REBOOT to complete the removal of what Ad-Aware SE found
Step #8

OK. Reboot your computer normally, start HijackThis and perform a new scan. Use the Add Reply button to post your new log file back here along with details of any problems you encountered performing the above steps and I will review it when it comes in.

OT
I do not respond to PM's requesting help. That's what the forums are here for. Please use them so that others may benefit from your questions and the responses you receive.
