News of another Word Macro virus called the "July Killer".

According to CNN:

==========================================================

A computer virus dubbed July Killer is expected to strike July 1 Active only during July, it will infect Microsoft Corp.'s Word 97 documents via a Visual Basic macro, according to anti-virus specialists

"The virus was discovered only recently and has a destructive payload," said Michael Lai, a system engineer at Trend Micro Inc in Hong Kong "It can wipe out the hard disk's contents."

"It is fierce because when an infected document is opened, it will first infect the global template, normal.dot, and thus opening other documents would lead to infection as well," Lai said

During July, users who open an infected Word document will see a dialog box entitled "A wake up call for the generation." If the user clicks the OK button, a message will appear that says, "You are wise, please choose this again later Congratulations."

If the user chooses the "cancel" button three times, another message appears: "Stop it! You are so incurable to lose three chances! Now, god will punish you."

The virus will then open the autoexec.bat file and add the command line "deltree/y c:\" to the file The next time the user boots the machine, all files in the hard disk will be deleted, according to Lai

He noted that users who have updated their systems recently will likely have the current fix for July Killer and should be safe

"Users who don't renew their antivirus software regularly are vulnerable," Lai warned

===========================================================

generates the above messages If you see these messages appear after opening an attached Word file, close the program and get an update to your current anti-virus program
