I've installed Mirc on two different computers and I can connect to servers other than undernet. When I try with either computer to connect to undernet I get the message "Auto [1] (Adi65) Infected with a virus or trojan, please clean your system, Cleaner @ http://www.mosoft.com (P8). I've run my anti-virus and even downloaded the trail version of mosoft and both computers check clean. Any suggestions would be appreciated.

Thanks

Use AVG.

Well, i have also facing this problem.

This often happens because someone connected before you with the same IP you have now and they were infected. Unless you can change your IP you'll just have to wait until the "ban" expires I believe.
