To completely get rid of the kak virus follow these steps:
--Click start, find, files and folders, type in the named: *.hta (star, dot, hta) and make sure you are looking in the c: drive, find now. Delete any instances you find.
--Once again in find files and folders type in the named: *.kak (star, dot, kak) and look in c: drive, find now. Rename the c:\AE.kak file to c:\autoexec.bat and delete all other instances you find.
And again in the find files and folders type in the named: kak.htm and look in c: drive, find now. Delete any instances you find.
Next, click start, run, type in regedit and click OK. That will bring up the system registry editor. On the left hand side locate HKEY_LOCAL_MACHINE and click the plus sign next to it, then down to SOFTWARE and click the plus sign next to it, then down to Microsoft and click the plus sign, then CurrentVersion click the plus sign next to it, then Run click the folder to open it and display its contents on the right. Remove the line that mentions cAg0u by hiliting it and right clicking it then go to delete. Click 'file', 'save' and close the registry editor. The entire string for that is:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Run\cAg0u
--Reboot the computer, start, shut down, restart the computer.

They also have a patch to fix this problem at: http://www.microsoft.com/security/Bulletins/ms99-0 32.asp
The patch is for the security hole in outlook express so you don't necessarily need it if you aren't running outlook. Good luck and let me know if you need further assistance!
