There was a security vulnerablity for that version and prior versions a year ago so it MAY have been fixed.
You could also scan the file here.
I'm sure you already know that using anything like this is somewhat risky such as an IM program but I know that you are cautious and well protected so you would probably be OK. I have never tried anything like this program myself.
Does anybody know anything, security wise, re: this "talk" program? I downloaded the exe file, it scanned ok with Avast, but an on line scanner suggested it might have "packers" ... has anybody used it and do you people think it would be safe to install (keyloggers, etc). Thanks
