VIRUS NAME : X97M/Fixen.a

Virus Characteristics

This threat is detected as X97M/Fixen. The virus contains one module v123 which infects Excel97/2000 workbooks. It saves a copy of itself as v123.xls into the Excel Application path. The virus also creates the file v123.vbs which is also found in the Excel Application path. The script file will export the viral code of v123.xls to v123.bas file. This .bas file is not viral.
