I assume you mean that you're getting this message when you try to connect.

Get a good virus program (AntiVir, AVG, or go to http://www.pandasoftware.com/products/activescan and let the web site scan your computer) and get rid of the virus. Then download a fresh copy of mIRC from http://www.mirc.co.uk, install it and it should work.
