Irc Chat Program, safe if used probly (When receiving files from unknown people, they could contain viruses or trojans)
Mirc is a chat program for irc (internet relay chat) Beware of some scripts that contain trojans etc. Scan with antivirus BEFORE installing!!
Is supposed to be a chat program but I've not installed it but was infected with it. Hard to remove it, sick trojan.
I am aware that mirc is some other program but in my case it came as a undetectable virus/ trojan witch disabled me from using task manager and regedit. To remove it I copied taskmgr to My documents and renamed it then I was able to use it and close the Mirc process
it is safe if u get from
It is malware and needs to be from your pc immediately. The people who "support" it are most likely people who intend you participate in malicious practices. REMOVE mIRC ASAP!

I donĀ“t install MiRC, but after reboot it running and I see it in the Process Tree... :o

Best practices for resolving mIRC issues

A clean and tidy computer is the key requirement for avoiding problems with mIRC. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
