Mirc 6.16 is the latest. All earlier version had exploits. I've used them and Avast is NOT reporting a false positive about them nor is Avast stopping mirc from working. And if I may say so myself. I know this for sure. I am a official helper in #windows95 (voiced), #nohack (voiced) #Avast (op), #windows98 (voiced). In most of the channels already several years. Did you people bought mirc or are you using a crack. MIRC is a trial version and the trial periods of the versions you mention are over.
