When you attempt to send an e-mail message with an attachment, you may receive one of the following error messages:
When you start Outlook 98, you may receive the following error message:
When you try to perform various operations, you may receive the following message:
MAPI32 caused an invalid page fault in module Kernel32.dll
When you try to start your computer, you may be unable to do so.
This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.
This behavior can occur if you have run the Happy99.exe virus program on your computer. When you do so, your computer becomes infected with this virus program.
To resolve this issue:
Happy99.exe is a 32-bit Windows-based Trojan Horse virus. When you run this program, it displays fireworks on the screen. It also creates two files named Ska.exe and Ska.dll, copies your original Wsock32.dll file to Wsock32.ska, and modifies the Wsock32.dll file.
The Wsock32.dll file cannot be modified if it is in use. If the Wsock32.dll file is in use when you run the Happy99.exe program, it adds an entry to the registry that runs Ska.exe the next time the computer is started, and then modifies the Wsock32.dll file. The modified Wsock32.dll file detects when e-mail messages and newsgroup postings are sent, and sends a copy of the Ska.exe file, named Happy99.exe, in those messages. All e-mail addresses that are sent a copy of the file are recorded in the Liste.ska file in the Windows\System folder. The Liste.ska file is a text file, and you can view it by using any text editor (such as Notepad).
