I agree it could be helpful to include a link to
http://www.mirc.co.uk/help/virus.html in the /help accepting files area of the help file.
However, to have some button to click in mIRC to go to an online scanner i disagree with. You cant rely on any one AV software or online scanner to catch everything, which is why in that link and in the sticky
trojan resources thread we suggest several things. Its always best to use more than one resource, and to close any open applications while running those resources. Many networks have info on their websites for resources and virus help channels as well.
