Ways to scan presence of antivirus software

May I know if it is any software (commercial, shareware, opensource) out
there to scan remote machines whether antivirus software such as Symantec
Antivirus or Mcafee's VirusScan has been installed. This would work in the
safe way in a network just like those Windows patch scanning tool for say
DCOM/RPC.

Thank you.

Have not come across any [ but there are bound to be some around ] This can
be done with a script, or simple program. It depends if you want to detect a
specific product or just all and any virus scanners. On a windows machine,
one could look in the registry for given keys, and then preceed from there
to see if the executable pointed to by the registry exists; if it did
conculde it is installed ( and probably working ). This method would be
about 5 lines of C program, and a similar size in windows script host.
