IDG.net: New 'Thursday' [Word macro] virus set to detonate Dec. 13Sep 02, 1999, 21:01 (0 Talkback[s])
(Other stories by James Niccolai)
"The Thursday virus carries a 'trigger' date of Dec. 13. When an infected document is opened on that date, it will attempt to delete all the files on a user's 'c:' drive, including subdirectories..."
"Unlike the infamous Melissa virus, which spread by automatically e-mailing itself across networks, the Thursday virus is spread when users share documents. However, because it appears to be spreading quickly, and because of its potentially destructive and costly payload, AVERT has given it a 'high-risk' assessment."
"...the virus turns off the Macro Warning feature in Word 97. If a user has a document that contains a macro, and the Macro Warning feature doesn't activate, that's a sign that their system may be infected, AVERT said."
"The virus, which also goes by the aliases 'W97M/Thursday,' and 'Thus.A,' contains a module called ThisDocument. After turning the macro warning feature off, the module proceeds to infect any Word documents opened or created on the computer from that point on."
