How can i make a vb.net application able to know if the user opening this vb.net application has an anti-virus or if the anti-virus is enabled.this will help me to improve my anti-virus
p.s i know that there are other anti-viruses which are good

You can check it by checking a registry key.

I belive they register it by adding it under this.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SecurityCenter.

I wouldn't even bother. You should specify in any documentation and during the install that multiple anti-virus packages should never be run simultaneously but, if a user is stupid enough to do it anyway, they are probably beyond your help.
