Macro.Excel97.Riots

Description Macro.Excel97.Riots

Excel macro virus, related to "Macro.Excel.Laroux". It infects Excel worksheets. It contains two macros in one module Riots: Auto_Open, Auto_Close, Fuck.
On opening an infected table Excel executes auto-macro auto_open which installs the virus into the system: copies the virus code to newly created file RIOTS.XLM in the Excel Startup directory. The virus then defines the "Fuck" macro as sheet activation handler, so the virus intercepts sheets opening procedure and infects them.
On file closing on 13th of any month the virus removes current sheet and displays the Balloon:
XM97.Riots!

Macro.Excel97.Sugar.a

Description Macro.Excel97.Sugar.a

These are stealth Excel97 macro-viruses. They hook windows/sheets activation and deactivations events and infect corresponding files. While infecting, the viruses save their code as "class" macros (see also "Macro.Word97.Class").
Sugar.a
It creates the infected BOOK1 file in the Excel start-up directory. It disables the Macro Virus Protection by direct access to the system registry.
Depending on the current minute, day and month, the virus inserts into the current sheet up to 200 cells with a text inside "-(Dr. Diet Mountain Dew)-", changes their size and color, and then inserts the message "The -[Sugar.Poppy]- by VicodinES" to the very first cell of the sheet.
The virus also contains the following comments:
'=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-'
'The Sugar.Poppy Excel Class Object Virus'
' written by VicodinES '
'=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-'
' Can I have a bottle of '
' WARM DIET MOUNTAIN DEW '
'=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-'

Sugar.b
This virus is very similar to the previous version. It also disables the Macro Virus Protection in the system registry, but does it with the help of MS Word: the virus transfers, to Word's global macros area, the AutoExec macro that by VisualBasic instructions disables VirusWarning when Word is executed.
This virus contains the following comments:
'-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-'
'Sugar.Poppy.II Excel Class Object Virus'
