X97M/Barisada.B
Analysis
- This virus is exactly like X97M/Barisada.A except
the name of the workbook created in the XLStart folder
is of a different name
- Virus hooks Excel event handler which prevents
the opening of infected files in order to run its
code
- Virus exists in the class code module, normally
named "ThisWorkbook"
- Virus verifies if it has infected the Excel environment
by searching for the file "rmc.xls" in the
XLStart folder - if the file does not exist, a new
workbook is created, infected and then saved as "rmc.xls"
in the XLStart folder
- On April 24th at 2PM, when working with infected
files, this virus may display a query message box
asking a YES/NO question -
"Summoning Xavier is the Ultimate Magic. Right?"
-
If the user chooses "NO", the virus may clear all cells from all sheets and from all open workbooks
