Have you tried scanning using Microsoft Windows defender?
Here. or Add aware from <a href="www.lavasoft.com" target="_blank">Here.</a> ?

Also you may need to try a virus scanner like <a href="www.kaspersky.com" target="_blank">Kaspersky</a> or <a href="www.symantec.com" target="_blank">Norton antivirus</a>.

I assure you that these scanners won’t detect mIRC as a Trojan. I blame Spy ware doctor
