Well if you didn't install it then someone or something did (mIRC certainly wouldn't download itself onto your computer and proceed to install itself). The default mIRC wouldn't cause any "lil red box with mIRC written in it" to appear on your screen either. That leaves three options:
- You or another user downloaded it, installed it and is now running a script on it. (possible)
- Something else has installed it on your computer and is running a script on it. (very unlikely)
- Something/someone/you else has [inadvertedly] installed a virus on your computer and the virus is one that pretends to be, or have something to do with mIRC (likely)
1, I suggest you ask anyone else who uses your computer if they have installed it on your computer
2, This is incredibly unlikely, if it did happen and it hasn't asked you about installing it then the overwhelming odds are it is a malicious script.
3, (In my opinion is still the most likely as norton doesn't detect everything, nothing does) it would
still a good idea to try scanning with another scanner.
Whatever this is it isn't default mIRC, it is like I said, either a virus, or a (possibly malicious) script.
You could also try these:
Press ctrl+alt+delete and close every program that is running and you know was never running before you got this problem. If the box dissapears do a search on the internet for the name of the last file you closed, hopefully you will find out what it is and how to safely remove it.
You can also try going to start -> run -> msconfig, clicking the Startup tab and looking for anything called mirc.exe or mirc32.exe and disabling it, but it would still be a good idea to find out what this is.
Another idea would be searching for mirc.ini on your computer, if mirc is installed mirc.ini will be in the same directory as the program.
I also forgot to ask an obvious question: If you double, left or right click it (the box with mIRC written in it) does anything happen?
These are all the idea's I've had, if none of them work I hope someone else can help
