The current release (r8.1) of this fine anti-virus software for Mac OS X has a problem in one of its startup scripts: it confuses Mac OS X 10.4.10 with Solaris 10, and the console will not open.
The default location for the script is /Library » Application Support » CA » SharedComponents » iTechnology » S99igateway. If you want to get the program working quickly (before the next update), comment out the check for Solaris 10 (lines 29-33). The ambiguous result is here:
SunVersion=`uname -a | awk '{print $3}' | cut -d . -f2`
I changed it to simply SunVersion="0", and the script than ran as expected.
