I just want to thank everyone for the help with my question regarding how to uninstall Mirc.
Everyone was right, I was hacked and had a GTbot virus, as well as an IRC trojan virus.
I was told how to get rid of these viruses and did it last night.
It was some kind of a "mimic" Mirc. The hacker used a program called "Network Crack Wizard 99." I did find a file which contained the name of the hacker and everything they did to my computer.
Thank you again.
