Hi

You are running HijackThis from a temp folder. You will need to move hijackthis.exe to a permanent folder, such as c:\hjt . This has to be done as HijackThis creates backups when you fix items. These backups could easily get deleted in a temporary folder.

First create a new folder:
A. Click My Computer icon on your desktop
B. Click C: drive
C. Click the File menu --> New --> Folder, a folder "New folder" will be created.
D. Rename it HJT

Unzip hijackthis.exe to the c:\HJT folder.



Download KillBox here: KillBox. Unzip it to your desktop.

Double-click on KillBox.exe to launch the program.

Highlight the files in bold below and press the Ctrl key and the C key at the same time to copy them to the clipboard:

C:\WINDOWS\system32\shdocvn.dll
C:\WINDOWS\system32\svcnt32.exe



In Killbox click on the File menu and then the Paste from Clipboard item
In the Full Path of File to Delete field drop down the arrow and make sure that all of the files are listed
Click the option Replace on Reboot
Now click on the red button with a white 'X' in the middle to delete the files
Click Yes when it says all files will be deleted on the next reboot
Click Yes when it asks if you want to reboot now
If you get a "PendingFileRenameOperations Registry Data has been Removed by External Process!" message then just reboot manually.

Your system will reboot now.


Run HijackThis!, press Scan, and put a checkmark next to all these:

O21 - SSODL: OLE Module - {0656A137-B161-CADD-9777-E37A75727E78} - (no file)


Close all other windows and browsers, and press the Fix Checked button.


Perform a full scan here: Trendmicro, check AutoClean and let him remove anything he finds.


Perform a full scan here: Panda Online, follow the instructions on the screed, make sure these are checked:
- Disinfect automatically
- Scan compressed files
- Scan e-mail files
- Neutralize Trojans
and let him remove anything he finds.

REBOOT and post a new log please.
Everyday is virus day. Do you know where your recovery CDs are ?
Did you create them yet ?

I went ahead and replaced the 2 files you had mentioned using Killbox. I reran HijackThis and saved a log for you to look at. You had given me instructions on several items to fix. However, looking at the new scan I made, I couldn't find them. Please look at the log and recommend the next step(s). Thanks!
