Norton AntiVirus Erroneously Reports "Bloodhound" Virus in MathType 3.5

The information in this document applies to:

MathType 3.5 (Win)

Norton AntiVirus (Win)


A few users of Norton AntiVirus who reported that it was erroneously detecting a "Bloodhound" virus on MathType 3.5 installation diskettes.


There are no viruses in MathType 3.5. According to Symantec, "Bloodhound" virus is a catch-all name for anything that Norton AntiVirus suspects may be a virus fragment or a variant of a virus. The MathType macros do not contain viruses. This problem has been corrected in Norton's current virus definitions files.


Symantec has determined that the virus warning is a false-positive and corrected this problem in their virus definitions that came out since the end of January, 1998. In order to receive significant protection from Norton AntiVirus, you must keep your virus definition files current, otherwise your computer will be vulnerable to new viruses.

If you are getting this message, you need to download the latest virus definition files from Symantec's website.
