wget http://securityresponse.symantec.co...ges/US-N95.html     <- wget, download URL to current directory
for getIt in `awk -F'"' '/=.+\.(zip|exe)\>/ {print $2}' US-N95.html`     <- awk, a powerful editor, it looks through the downloaded file, searches for lines that contain a string that begins with a "=" and ends in either ".exe" or ".zip", and returns the 2nd field in this line; -F sets the field delimiter (' ' by default, '"' in our case; look at the html file with an ASCII editor and you'll know why). The matching lines (6 at the time I downloaded) are handed over to the shells built in list-feature by including the whole awk-thing in "`". Now the shell will run the loop that's defined by do/done for each occurence awk found,
do     <- that is, it will wget six files (their name each time in the variable $getIt); since the strings we found were relative addresses we just prepend them with the symantec website, concatenating the string
  wget http://securityresponse.symantec.com/$getIt
done     <- end of loop
