Forums mIRC Help IRC Flood Trojan

I get an IRC Flood trojan whenever I use mIRC. I deleted and reinstalled mIRC using the mIRC website download, and still get the trojan whenever I use mIRC.

My spyware program finds the trojan after every visit to mIRC and removes it each time, but it comes back when I go to mIRC again.

Any idea as to preventing the IRC trojan flood?

Thank you!
