Good!
Sorry my english, I’m russian. Used to love handles to catch viruses. Wish. In Your antivirus, you can embed an automatic function to determine site-the distribution of viruses via whois to his hoster (and his e-mail) and automatically sent to him (the hoster) a letter of costamesa he is the distributor of viruses with the host wish to do hostdime as undermining the reputation of the hoster. I think it will raise Your reputation as fighters against a virus, among users, there are also many who understand and support the idea to insert the piston to virusaction. This feature will be beneficial to distinguish Your antivirus from others. Good luck in the fight against viruses.
P. S. If not difficult for you, so this letter got to Your programmers.
