The following info was "cut and pasted" from the SYMANTEC Virus Information Center. It explains how and what to do. Hope all is well. IF you didn't open it, you are probably okay BUT it would not hurt to check.

Happy99.Worm Aliases:Trojan.Happy99, I-Worm.Happy Likelihood: Common Region Reported: World Wide Characteristics: Trojan Horse, Worm Description: This is a worm program, NOT a virus. This program has reportedly been received through email spamming and USENET newsgroup posting. The file is usually named HAPPY99.EXE in the email or article attachment. When being executed, the program also opens a window entitled "Happy New Year 1999 !!" showing a firework display to disguise its other actions. The program copies itself as SKA.EXE and extracts a DLL that it carries as SKA.DLL into WINDOWS\SYSTEM directory. It also modifies WSOCK32.DLL in WINDOWS\SYSTEM directory and copies the original WSOCK32.DLL into WSOCK32.SKA. WSOCK32.DLL handles internet-connectivity in Windows 95 and 98. The modification to WSOCK32.DLL allows the worm routine to be triggered when a connect or send activity is detected. When such online activity occurs, the modified code loads the worm's SKA.DLL. This SKA.DLL creates a new email or a new article with UUENCODED HAPPY99.EXE inserted into the email or article. It then sends this email or posts this article. If WSOCK32.DLL is in use when the worm tries to modify it (i.e. a user is online), the worm adds a registry entry: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\ CurrentVersion\RunOnce=SKA.EXE The registry entry loads the worm the next time Windows start. Removing the Worm Manually 1.delete WINDOWS\SYSTEM\SKA.EXE 2.delete WINDOWS\SYSTEM\SKA.DLL 3.in WINDOWS\SYSTEM\ directory, rename WSOCK32.DLL to WSOCK32.BAK 4.in WINDOWS\SYSTEM\ directory, rename WSOCK32.SKA to WSOCK32.DLL 5.delete the downloaded file, usually named HAPPY99.EXE Windows prevents you to do step #3 and #4 above if the machine is still connected to the Internet. The file "windows\system\wsock32.dll" is used whenever the machine is connected to Internet (i.e. through dial-up or LAN connection). If you are using dial-up connection (i.e. America Online), you need to do the following: 1.terminate internet connection 2.delete WINDOWS\SYSTEM\SKA.EXE 3.delete WINDOWS\SYSTEM\SKA.DLL 4.in WINDOWS\SYSTEM\ directory, rename WSOCK32.DLL to WSOCK32.BAK 5.in WINDOWS\SYSTEM\ directory, rename WSOCK32.SKA to WSOCK32.DLL 6.delete the downloaded file, usually named HAPPY99.EXE If you are connected to Internet through LAN (i.e. in the office or cable modem), you need to do the following: 1.From the Start menu, select shutdown-restart in MS DOS mode 2.type CD \windows\system when DOS prompt (C:\)appears 3.type RENAME WSOCK32.DLL WSOCK32.BAK 4.type RENAME WSOCK32.SKA WSOCK32.DLL 5.type DEL SKA.EXE 6.type DEL SKA.DLL Safe Computing This worm and other trojan-horse type programs demonstrate the need to practice safe computing. One should not execute any executable-file attachment (EXE, SHS, MS Word or MS Excel file) that comes from an email or a newsgroup article from an untrusted source.
