If you reinstall mIRC, you're reinstalling the default scripts.
As mIRC scripts allow for a great many things, custom scripts (i.e. scripts made by you or other users) may be a security issue (...you have to either review the code yourself or trust a source/review). This does not apply to the default scripts (i.e. vanilla mIRC), even if you accidentally removed some part of it, as they don't contain "sensitive" commands.
thank you so much dear Horstl, your reply really helped me to feel better, at least now I know editing default scripts don't cause a security threat, thanks so much once again!
I am sure the script I saw was not made by me (I couldn't write a script even if I wanted to!) neither I have uploaded a script file before to add to my IRC. it was there when I clicked the menu and checked the remote section and after checking half of it, it seemed so complicated to me that closed the window. :-s
and I have a question if you don't mind: when people add custom scripts to their IRC, if they uninstall the mIRC, they will lose the script and later should add that script to their new IRC again?
and is there a log file to show your scripts has been edited?
so sorry that I am troubling you with all these question I know I still have a lot to learn about IRC
