Forums mIRC Help PC cutting out and now have Mirc61 infected Mesge

Have run every spy, antivirus program I can get my hands on.

My PC just freezes or I get a Black screen and pc just stops when downloading.

I am now back on latest Mirc version but also still get an error message Infected with mirc61 from some chanels.

I have removed almost everything from my PC. All I can think of now is formating hard drive and starting a fresh.

But before I do this drastic action, has anyone got any more help for me.

THANKS.
