Ok I have ran Sophos, Norton, Mcafee with all current updates and they do not find any virus. I do a online scan from housecall and it finds the following item Dos_AGOBOT.HM and the locations is
C:\WINNT\SYSTEM32\DRIVERS\ETC\HOSTS and it can not clean it so I have it delete the file..

Then I boot in safe mode and delete the file again. I have ran Adaware, spybot,Hijackthis. Hijackthis did find Netsnake on this system and had it fix that

Have delete trash, IE cookies and files

Still have this piece of crap any help by the pro's

Thanks

DOS_AGOBOT is a byproduct of the actual virus WORM_AGOBOT.HM. You get this virus by a vulnerability found in Windows. So make sure you immediately update your windows by going to

http://www.windowsupdate.com

This worm is what is creating that hosts file.

You can find removal instructions here:

Agobot.HM Removal Steps

Follow these instructions. Reboot, download HijackThis from here:

HijackThis

Save it into its own directory. Make sure all Internet Explorer windows are closed and run the program. Click on Scan and have it save a log. A notepad window will open with the contents of the log. Paste those contents to a reply to this post.

These three entries look strange. Looks like it could be a trojan/worm that was added as supposedly a Audio Device Loader, but they mispelled audio. I could be wrong though.

Also are you running an excel sheet on purpose on startup? If not you should fix the Startup: personal.xls.

You can fix these:

O4 - HKLM\..\Run: [Audoi Device Loader] smssv.exe
O4 - HKLM\..\RunServices: [Audoi Device Loader] smssv.exe

Only fix if you are not supposed to be opening an Excel spreadsheet
O4 - Startup: PERSONAL.xls

Reboot and move these files to another directory until they are examined and to determine they do not cause any problems with not being loaded:

c:\windows\smssv.exe
or
c:\windows\smssv.exe

If you can email this file to [email protected] so I can take a look at it.
