How do I clean my system???

To remove the virus without any antivirus software,reboot in the MSDOS mode. Then go to the windows/system directory by typing

c:\windows>cd system

Then,delete ska.exe and ska.dll by typing:

c:\windows\system>del ska*

Then delete wsock32.dll by typing

c:\windows\system>del wsock32.dll

Then rename your original wsock2.dll, which was renamed by the worm to wsock32.ska back to wsock32.dll. To do so type the following at the DOS Prompt:

c:\windows\system>ren wsock32.ska wosck32.dll

Hope you could do this

All the best
