Brief Description 

    

Opaserv.Y is a worm without destructive effects that only affects Windows Me/98/95 computers.

Opaserv.Y spreads to other computers by attacking IP addresses, in which it tries to make copies of itself to the existing shared network drives. It attempts to access these shared drives by exploiting the Share Level Password vulnerability.

If you have a Windows Me/98/95 computer, it is highly recommendable to download the security patch from the Microsoft website. Click here to access the web page for downloading the patch.

Visible Symptoms 

    

Opaserv.Y is difficult to recognize, as it does not show any messages or warnings that may indicate that it has reached the system.
