If you care about MP3 quality, go in the registry where Jas101 mentionned and there should be a setting like SetBitrateLimit=1 or similar. Set it to 0 to enable searching for 160+ kbps quality songs. It's pretty elementary, but it's a good way to get better-sounding songs easily...
Seriously, mirc is much more safe than any other program if you are not a newbie. I still remember the old 1995 virus called "script.ini", many people will just accept that file and then open it with mirc.
You need to be certain of what you asked and who's sending, also looking at the file extension (which is never hidden in mirc) is good to avoid accepting trojans and stuff like that.
You mean you shouldn't just accept whatever anyone tries to send you?
Shit, maybe that's what my problem was.
Seriously though, by looking at my firewall logs, I have had probably 90% of the attacks I have had while signed into mirc, especially Dalnet. And I've gotten the majority of my crap files from Dalnet as well. (They say they are one thing when they are really another.)
ohhh yeah, the port attack, that's common, there are people there that just want to screw you, i've never experienced any hacking, except the usual nuke (connection reset by peer).
I dunno about DULLnet, but Zerolimit masks your hostname and IP address.
For example, instead of showing me as fury@12-222-140-###.client.insightBB.com, it shows me as [email protected] where xxxxx is a set of random numbers, and if my hostname doesn't resolve, instead of showing me as [email protected].### it shows me as [email protected]
